What demists your car windscreen quicker on a cold and wet day - warm air from the heater or cold air from the aircon?
You have to heat the windscreen in order to make the water dissolve into the air again.
When the screen gets too cold, the air directly around it inside the car will also be cooled. The maximum degree of humidity of air depends on its temperature, and the cooler it gets, the less water it is able to contain. Therefore water that can not dissolve in the air will condensate - on your screen. Heat it up and it will dissolve again.
More than likely the heater core is leaking coolant. Replacement of heater core is all you can do with that.
Is it possible to replace a heater matrix without taking the dashboard out on a daewoo matiz year 2000?
No, there'no other way. If your car has no aircon the job is does not take to long and isn't too difficult - wth aircon that's another story... Alternatively you can bypass the heater element in the engine room, tricky because theres little space but possible
You remove the heater core by removing the entire dash assembly. Remove, glove box, centre console, top dash pad, dash facia, headunit sorround, all aircon controls etc etc, then remove the HVAC unit which has the heater core inside it, HVAC can be removed once 5 bolts are removed from the engone bay holding it in place and heater hoses disconnected from the heater core, note - coolant must be flushed first, and aircon gas… Read More
The coolant valve to the heater sits above the heater matrix on the inlet pipes. It can be accessed from under the bonnet near the bulkhead below the windscreen.
under bonnet behind windscreen washer bottle inside the black heater motor box you need to take wind screen bottle and arm atture to get at it
depending on the year, mines 2007,its in the dashboard on the drivers side, little flap, 7th fuse down 10amp.
You might have a small leak in your heater core, had that problem with my 96 Jetta. Had to replace it.
It would greatly depend on the ambient temperature and the humidity of the atmosphere you are driving though.
Because there is much in the house that runs on electricity. Lights, fridge/freezer, the kitchen range. water heater. TV, wi-fi, aircon etc etc
A block heater for a Honda Accord helps to quickly raise the temperature of the car to the proper heat level. This allows for a quicker engine start-ups.
You will need to disconnect the aircon hoses first.Then the fan unit. I don`t know if you have to take the dashdoard off. Maybe the heater core comes out the bottom after you remove the fan. Just looking at my Starlet. Looks tricky. Maybe someone else can be more specific about the cores removal.
yes fish can be in a/c room just run aquarium heater in tank and watch your thermometer freshwater shouldn't go below 68degreesF saltwater shouldn't go below 74 degrees F
easy way is to find where the water is go through the fire wall into the car, take them off and flush with a garden hose, but if badly blocked, you may end u taking the hole dash out. if you have aircon the heater matrix is behind the radio the air con matrix is behind the glovebox long job.
If it is a electric water heater, then one of the heating elements are burned out.
When Ice on a car windscreen will disappear as you drive along even without the heater on explain why this happen?
the ice is removed by the friction in the air , small fragments are automatically removed the solid due to highpressuregets evaporated
If the temp fluctuates There is a blockage in your heater radiator. ( water runs through it always) Shows up more going up hill or when the aircon is on. Bypass the heater to check. The main radiator could do with a flush. With the heater bypassed there is no burping needed or airlocks in the system. I put a head gasket fixer through the system in case the overheat caused any problems. No problems… Read More
The block heater cord on a 2010 Ford Escape is located along the side of the engine near the oil dipstick. It is held in place with mounting bolts and warms the engine quicker in cold weather.
easy! disconnect the battery for 15-20 mins *. Darren Nunez * this does not 'disarm' the alarm, to do this, remove the service fuse #12. be warned that you will loose the computer and the aircon/heater if you do this but it stops the alarm going off! - nbc
There are two ways 1). Bypass the heater in the engine room (unless of cause you life in a colder climate) This will require very long arms and very small hands, and not to forget: a lot of cursing!! 2). You have to remove the entire dashboard, including steering weel, centre console, airbacks, instruments, aircon and vann assembly - a real pain!!
Ford fiesta 1.3 ohv 1998 heater not working. only blowing out cold air have replaced thermostate but still not getting hot air?
THIS IS A COMMON FAULT ON FIESTA'S THERE IS A HEATER CONTROL VALVE INSIDE THE ENGINE BAY JUST BELOW THE CENTRE OF THE WINDSCREEN WHICH HAS THE COOLANT PIPES CONECTED TO IT. IT IS A CHEAP PART TO REPLACE AND IS EASY TO FIT.
If you set pool heat pump at temperature above the temperature you want will the pool heat up quicker For example setting it at 100 when you want pool at 80 quick?
It works this way. Even if you could set the thermostat at 200 it will not heat the water any quicker. It sounds as if you have an undersized heater. A larger heater will heat the water faster if your system can upgrade to the larger size heater. Your house will not heat up any faster if you set the thermostat to maximum. It is the output capacity of the heater that determines how fast… Read More
When i have a few people in my car (when i say few i mean more than me) i cant see anyting out of my windscreen or my side windows... Even if i put my blowers on the windscreen and on full whack i can only see in about the bottom 4 inches of the windscreen which means i have to drive like an old granny any ideas on what i can do or how… Read More
400 k BTU - But it depends on the gas line size feeding the heater; how long that run is etc. The larger heater will heat the water quicker thus cost for heating will be less ( than if you used a 250K BTU)
Mercedes clk yesterday heater fan wont blow checked the fuse seems ok when switch on you can hear click noise under the bonnet?
I have a clicking as you describe on my CLK. I have also noticed the windscreen demister not so good. I have taken it to an independent mechanic who says this is a recognised fault and is due to a cog slipping on something in the heater. He tells me it is a main dealer job and is likely to be over £1000 !
possibly you've got a stuck up water valve that's why the hot water continously flows to the heater coil, for the meantime to cut it off open the car hood and look for two rubber hose that is being connected to the engine side and the other end is connected to a aluminum or steel tube that is coming out of the dust board front in the hood. it is the water supply going to… Read More
I've been trying to find this out too (for a mark III Golf). The smell's more noticeable in heavy traffic, I sometimes see smoke coming out of the air vents when the air's not switched on, and find condensation on the windscreen. It seems to be a problem with the cooling system. The coolant leaks onto the engine where it's burnt off. Maybe the heater core?
A braided 3/4" stainless steel hose can be installed on cold and hot water line for a quicker disconnect.
The engine would heat up quicker without the heater on but ever so slightly, so it probably doesn't matter.
Does the car have air con? If so there could be a build up of bacteria in your heater system that needs to be treated. take to local dealer to have the system sprayed. If no air con, are you losing coolant from header tank? Could be an indication of heater core leaking. Check to see if carpets are wet! If no coolant loss then it could be a leaking windscreen, roof, etc. Hope this… Read More
the hot water from the engine does not enter the heater coil placed under the dust board of the car because the water valve controlling it is not being activated. Possible cause no supply of 12 volts or the coil of the valve is already burnt out. Have it check by a professional car aircon technician. But first look up for the fuse of said control possibly you've got only a blown fuse. Try to… Read More
Grip the central fan control knob and pull to remove it. (Make a mental note of whatever setting you currently have the fan at - you will need to replace the knob in the same position). In the cavity behind you will see a single bulb, which illuminates all of the the heater, fan and aircon switches & dials. To replace it is quite tricky, due to the confined space. I would recommend using some… Read More
Two reasons that I can think of. 1) Engines like to have a certain operating temperature. Especially computerized vehicles. The thermostat in the closed position will keep the coolant contained within the block itself to not only speed up the warming process, it will also maintain that operating temperature by opening, and closing as needed. The onboard computer in today's cars depend on the engine temp. to regulate other systems such as fuel (air/fuel ratio)… Read More
The simplest solution is to purchase an electric dipstick from almost any auto parts store. It will heat up the oil for faster starts and quicker warm up.
The simplest answer might be that it is just low on coolant. It may not overheat, but there is not enough to get up to the heater. Thermostat may be stuck open, Heater core may be plugged. One of these may be the answer if it is a new problem, if it does it every year, it may not have a hot enough thermostat. Water level first thing, then thermostat. You can try covering 1/2… Read More
Not a very easy job. I had to do this because I broke the heater changing the chassis/body rubbers. I did this a few months ago so detail is a bit rusty. Note this was anAustralian right hand drive car. In summary: Not sure if necessary but I disconnected the Battery because I would be playing with the steering. Didn't want the airbag to go bang. In the engine bay, disconnect the heater hoses from… Read More
A short somewhere in the system. Most likely the top heating element shorted out and caused the breaker to trip. The top element seems to go bad quicker for some reason. At least that has been my experience.
I had the same problem on my '96 lwb t4 caravelle VR6, I found a 10A blown fuse (whilst looking for windscreen wiper fuse which was also blown as I hadn't freed the wipers from the snow/ice on the screen before activating them) and when replaced the problem was cured. I think the reason why this worked, is that particular fuse supplys the mixer valve that adjusts the heater water temperature and when there is… Read More
It won't do you much good. In fact, it won't do you any good at all. You'll only get it to blow hot air (which is what the heater is for), and, eventually, you'll destroy your AC compressor, causing it to have to be replaced, along with your accumulator (if you have a fixed orifice tube system) or your receiver-drier (if you have a Thermal Expansion Valve system). The refrigerant carries the compressor oil through… Read More
Well, you've got a leak somewhere. It can be a bad heater core, a bad windscreen seal, something wrong with the intake plenum for the passenger compartment fan or some other leak. A heater core leak should show up as dropping coolant levels, so unless you've got that it has to come from outside. My suggestion is - once it's dry, get in the can and have a friend hose it down with you in… Read More
under the scuttle which is the plastic trim at the bottom of the windscreen where the wiper arms are , Take the trim off on the right hand side (drivers side English vehicle) you can now see the heater blower motor box ,the resistor fits to this box and will probably be mounted round the back of it where you cannot see, it should have a 7 or 8mm headed screw holding it in place… Read More
It depends on a large number of factors. Amongst them are: the fuel efficiency of your car, condition of the car - whether or not the engine is well tuned, tyre pressure etc your driving style - lots of acceleration + braking or driving at a steadier speed number of passengers, other load whether or not aircon or heater are in use (sound/lights normally make little difference) road conditions including climbs and descents
If the heater does not work, check: -heater fuses and/or any heater relays -heater control head -heater blower motor resistor
I had the following problem with the heater on my '99 Passat (B5). The damper blade in the heat/aircon mixing plenum is fabricated from a piece of sheetmetal with large holes punched in it. The holes are covered with self-adhesive polyethylene foam about .5mm thick. After some years the foam becomes brittle and blows away. Really first rate automotive engineering.......I don't think so! Maybe VAG were so proud of this piece of junk that they… Read More
Doing this right now, very difficult,following manual instructions. Basically Dash to be removed to gain access to heater box nuts. Requires removal of centre consoul, Glove box,Steering column and Air bags which i have done. I stopped at the suggestion of degassing the Aircon, and successfully removed the old cables after raising the heater box slightly, removed the insulation between the heater box and firewall stuggled for an hour loosening the bridging plate and pulled… Read More
What heater? heater in your house? heater in your water bowl? There is probably salt and/or other minerals on the heater that he is licking off.
There are a few causes here. First of all check you have enough coolant, if it has run out there will be no heat transfer from coolant to heater radiator. This is dangerous to the engine. If it has coolant, then try back flushing the cooling system, especially the heater matrix to remove any foreign object that could be causing a blockage. When refilling, fit the antifreeze first then start the engine. Make sure you… Read More
Firstly get the A/C system de-gassed and the springlock fittings undone. then remove heater hoses in the engine compartment at the firewall.(do not drain coolantyou only loose about 500 ml) remove :5 X 11mm nuts from the firewall one is located beside the battery :disconnect battery :unplug vaccuum hose above the heater pipes go inside remove the following :the cup holder in front half of the console remove gear shift boot to access screws remove… Read More
This switch turns on an electric element inside the heater box so that you can warm your toes and defog the windscreen while the coolant temperature is rising in the engine. The idle speed does increase while the coolant is cold to compensate for the 25 amps or so that the element draws from the battery. As the coolant temp increases the element will switch off and the idle speed will go back to normal.
The heater coil and a heater core is the same thing. Hot water circulates from the engine and through the heater core then back to engine generating heat for your heater system.
This is called resistance heating. Your standard incandescant light bulb is a great example of a small electric heater. The tungsten filament presents a resistance to the flow of electricity thereby heating up the filament. Because of the properties of the filament the heating also produces light. The resistance of the heater element is such that most of the energy consumed is in the form of heat and not light although ultraviolet light is emitted… Read More
