Why is my 86 Mazda rx7 coolant over flow fills up to the point that it over flows and over heats new radiator new rad cars and new thermostat?
The impellers on the water pump could be rusted out and you're not getting coolant flow. The head gasket could have blown out if the engine overheated. Overheating the engine, especially many of the more "flimsey" foreign engines, will cause the head to warp resulting in head gasket failure. You can get a test strip that will sense carbon monoxide in the coolant. If you find carbon monoxide in the coolant, the head gasket is leaking. nope rotarys dont have head gaskets !!!!!!!!!!!!!!!!!!!!!!!!!! or pistons either!!!!!!!!!!!!!!!!!! check for air in system. radiator has bleed valve on the side of inlet pipping (top hose) undo valve and fill coolant until it comes out of bleed valve, close bleed valve and top coolant off, to better insure that air is out of system, due to angle of that means raise front end of vehicle make shure that rad cap is off and heater is on at full blast hot, start engine and let it run until air is out of system and thermostat is fully opened, can determined by bubbles coming up in radiator fill housing (where the rad cap goes) once coolant all goes down and is at constant flow then thermostat is fully opened, shut off engine top off and cap it up.
What else can I help you with?
How do you bleed the radiator to get air out on a 1987 Mercedes 300E?
In order to "purge" the cooling system, you need to detach the top hose that goes from the thermostat housing to the radiator (detach the end that connects to the radiator). Pour coolant into the hose until it fills halfway and reattach.
1988 f250 7.3 diesel very high pressure when removing radiator cap even when cold when shut off coolant reservoir over fills runs hot?
May be a defective thermostat - not opening May be a blockage in system
Where is radiator filler cap on a Skoda fabia?
Has none. Fills from bottle.
Will blown head gasket cause car to not start?
It can if the cylinder fills with coolant.
Refill a radiator on a vehicle with no cap?
You use the coolent reservoir bottle to fill the radiator. It should fill the rad before it fills the bottle.
Why would 1989 Sundance When you drive it 3 or4 miles pressure builds in the radiator and pressure pushes the fluids into auxiliary holding tank This fills where the fluid is lost through the overflow?
Sounds like either the thermostat is not opening and needs replacement or head gasket is bad
To change thermostat in vw 1982 rabbit?
Put the car front end up wheel ramps, or if you do not have ramps but do have some 2x6 lumber lay the lumber down on the ground and stagger the second board over top of the first. This gives you a basic ramp for one tire and you raise the car 3 inches off the ground. Because this is work you got to do underneath the car. Get a clean 1 gallon pail so you can collect the coolant. Open the hood and remove the black cap that holds the coolant so air can get in. . Get into your dirty clothes and have a 10mm socket on a 5 " extension and on a ratchet 3/8" drive is good enough. . Crawl under about where the passenger sits. Follow the big bottom rad hose and that connects to the thermostat housing that is held in place with 2 black 10mm bolts. No imperial measure or inch socket will work here. 10mm or nothing. Loosen the bolts rotating counter clockwise. Have the bucket nearby and loosen one bolt but do not remove it, then loosen the other some and then use your hand and pull down on the big hose right near the thermostat housing and it will wiggle loose and start Peeing out coolant in a thin stream. Now, I am not in a rush so let it come out at a controlled speed so you collect it all. You can reuse it later. At this point I go have a coffee...rather than lay under the car. When the dribbling stops, remove the bolts and CAREFULLY REMOVE THE IGLOO THERMOSTAT HOUSING. A reusable rubber "O" ring will come out as well. There is no paper gasket. Now if you look straight up where the housing was you will see the thermostat up inside. If this is the case, then use your fingers to pull on it and hopefully you still have the bucket there because another 2 quarts will run down your arm and into the arm pit. Surprise ! Now you have removed the thermostat. Putting it in is the reverse of removing it. NOTE If your problem was no heat or overheating then it is not the thermostat you should be looking at. It most likely works dandy. To fill a VW radiator, you remove the upper rad hose and fill the rad hose up with coolant...this fills the back half of the engine that submerges the thermostat in coolant, submerges the temperature sensor in coolant so the rad fan clicks on to cool the motor when hot AND fills the heater core with coolant so it gets hot. . Then you put the upper rad hose back onto the radiator and tighten the clamp. Then fill the upper coolant tank with coolant as full as you can fill it(no air space) and put the black lid on. . Then on the passenger side inner fender there is another coolant tank which you HALF FILL UP WITH COOLANT. The lid on that tank is loose and is suppose to be loose. It just pops off when you push up with your thumbs,(and snaps down) It is meant to be loose because as the coolant heats up it expands and pushed the air out. > when the coolant cools down say overnight it sucks in air. You engine expands and contracts like your lungs idea. Then drive car and check the coolant level in the overflow tank (which is the tank on the passenger fender) the next morning when it is cold. You never want to be at MIN. because then you are sucking air. It is a quick "Eyeball check to see if you have enough coolant" It helps when the coolant is colored as it is easier to see the level.
Should steam radiator valves always be open?
Steam radiator valves should always be fully open, or fully closed. Steam enters the radiator from the boiler, and fills the radiator. The air vent shuts, having sensed moisture inside the radiator. The steam then cools, condenses to water, and drains from the radiator. If you leave a valve partially open, then the steam enters easily, because of the pressure. But, the water has a difficult time draining, so the radiator can collect it, and steals it from the furnace, which needs it for resupply.

How much water fills the radiator hold for Chevy Astro Van?
the water is very important to the wworld so in order to make it radiator it needs some love and care, thats wht makes the world go round and the chevy astro van is in the world so it alll makes sence(:
How do you make a 1995 Subaru legacy stop overheating?
Make sure cooling fan is workingAnswerThere are three common problems for over heating. The thermostat is stuck in closed position and not circulating the coolant flow once the engine is warmed up. The water pump is not working properly and needs to be replaced. and lastly the radiator need a good flushing and coolant change. Try flushing the system and replacing the thermostat. Then see how the system runs after that. Hope this helps you. Brad. AnswerA fourth problem common in Subaru engines is a leaking head gasket where pressurized exhaust gasses enter the cooling system. A service center can test the coolant for traces of exhaust residue. As the engine heats and cools, the system "breathes" through the radiator cap, typically holding the pressure in the engine to a max of ~15 pounds. The expanding water flows through the radiator cap into the reservoir when the engine heats up, and is sucked back in as the water cools. If exhaust gas is forced into the system, it gradually fills with air (sometimes only under a heavy load), causing more coolant and some air to vent into the reservoir. When enough coolant is expelled the reservoir overflows onto the ground. Eventually enough coolant leaks out (possibly over several trips) to cause a boil-over.A common symptom may be a reservoir that seems to be constantly emptying itself with no sign of leaks (because the water leaks out mostly when you're driving). If it's really bad, you may see bubbles surfacing in the reservoir. Good Luck!AnswerAnother thing to look into is whether or not both cooling fans are running when it starts to get warm. i personally have a 95 Legacy doing the same thing. i noticed one fan was not running when the car was getting warm. when i ran power and ground directly to the fan it came on. this leaves the possibility of a bad relay, bad cooling temp sensor, or even a problem with the cars ECU. not as common of an issues as the others but still something simple to look into.
When you warm up your car in the driveway cold air enters the cab then as you start to drive down the road warm air enters cab?
hi,most likely you have low coolant level in radiator,at idle you have an air space in heater core,causing poor heat,when you move and engine speed increases, water fills heater core,you get heat,.another possible cause is a clogged heater core,but check fluids first.
