check out fan relay,ac risistor assy.,radiator pressure cap,head temp sensor,water pump and clog radiator or thermostat bad or bleed off air in close loop systems.that should do it.
Your thermostat is sticking in the closed position,it is usually located where the top radiator hose connects to the engine. Very inexpensive item
Follow the top radiator hose from the Radiator to the engine. The thermostat is locataed under the housing that bolts onto the engine
In the top radiator hose fitting opposite the radiator, on the engine.
hi i have a ford focus 1.6 2000 and it keeps overheating I've removed the thermostat but the problem continues the expansion bottle bubbles and the top radiator hose were the thermostat is attached gets really hot but the bottom hose were the water pump is connected to is cold' i don't know if the water pump is working or not as there is no rattles or noises coming from it can anybody help please thanx
Yes, but just below the thermostat.
Check the thermostat first. I had an intermittent overheating problem on my 02 for almost a year, changed the thermostat and it never happened again. If that doesn't work, secondly I would check the water pump.
On the opposite end of the top radiator hose, away from the radiator, in the inlet fitting.
your radiator needs to be replaced
Normally the thermostat is located at the point where the upper radiator hoses connects to the engine.
Replacing the thermostat in a 2000 Ford Focus SE wagon is very easy to do. First the radiator hose will need to be disconnected from the thermostat. After the hose is drained and disconnected, the thermostat can be removed by taking the two bolts off.
Probably in the housing at the engine end of the upper radiator hose
Lok at the engine end of the upper radiator hose no its not its at the lower end of the radiator hose end
It is located at the point where the upper radiator hose connects to the engine.
Follow the top radiator hose to where it meets the housing that goes into the driver's side of the engine, the thermostat is in that housing.
Should be located in a removable housing at the engine end of the upper radiator hose
Did you ever find an answer to this question? My 2002 Focus is doing the same thing. The water pump and thermostat have been replaced, but the temperature gauge still show that it gets hot if I drive the car for about 30 minutes in stop and go traffic. If I slow down or stop, I will see the needle move. Once I get going, it will come back down to normal or will do so once the fans kick in.
Unanswerable - not enough detail - the engine has to be at temperature for a while before the thermostat opens and so allow circulation, until then, one hose will be cool and one hot.
Unless I have drained the block and radiator, I have filled the radiator from my expansion tank in every vehicle I ever had. If you have drained your radiator and it is cold, take off the cap and fill it that way. If you have drained the engine block and have not change your thermostat, you will need to keep filling your expansion tank until everything is filled back up. I recommend changing your thermostat.
Or, if everything else is operating properly, it could be the thermostat or a blocked radiator, but I'd focus on the thermostat first. Be certain that the engine is at normal operating temperature when looking to see if coolant is circulating. A properly operating thermostat will prevent the circulation of coolant while engine temperatures are below operating temperature.
To replace a lower radiator hose on a Ford Focus, use a bucket to catch any antifreeze that might leak. Loosen the clamp from both ends on the hose that needs to be replaced. Put the clamps on the new hose and reposition the hose on the radiator and the other end where it needs to go. Tighten the clamps. Refill the radiator with antifreeze.
The cost of a radiator in a Ford Focus will depend on the year of the car. A 2007 Ford Focus radiator will cost an estimated $63.66 at the website, CarParts.
A water pump? In all vehicles that I've had and know of. Your radiator has an intake and an outtake, Your intake goes from the radiator, to the thermostat, the thermostat connects usually directly to the water pump or only has a few inch distance from that.. It circulates the coolant around / in the block. and feeds it out of the block usually on the opposite side, it registers on your vehicles thermometer (the thing that tells you your engine temp) and back in to the radiator.
So far you've done all the right things. Have you considered also having the radiator flushed? Have you replaced the hoses? As the hoses age, they get soft and can collapse when under suction by a properly operating water pump.
I had this exact same problem.........if it is only overheating while in traffic at an idle and the fans do cycle while the heatac is on then i have good news for you. Between the two fans in the engine compartment, there is a plug that is identical to the ones holding the wire to the fans. Remove this and check to see if it is burnt.. If it is you need a new blower resistor and a new pigtail connector for it.....both are cheap and very easy to replace. peace
