If the car go over 120km/h the heat gage rises. I've replaced the fan blade, waterpump, radiator and thermostat. what else could be the problem?
SOURCE: overheating, after 4 or5 miles engine gage is in
Please solve this problem, my car COROLLA 1988 automatic 1.6 has the same problem!!!!!
SOURCE: my car is overheating
Hello, You did not indicate what vehicle this is. But in general, most cars have 2 water sensors. One makes the dash gauge work and the other makes the Electric radiator fan work. Check with a good Autoparts store like Autozone, Oreilys, or Advance for parts application. These stores will also scan your vehicle for free.
When you have an Electric cooling fan there are usually 2 speeds on them. When the engine is really hot(Overheating) and when the A/C is switched on, most will run on High speed. You can sometimes have only low speed and the car will be Okay until you get in slow traffic or use the A/C. There are Relays for the fan which turn on when the water sensor(remember there are usually two)activates them.
These are things to test. If the water temp sensor is working, if the relay for the cooling fan is working, or if the cooling fan motor is bad. Check the fuse panel for a blown fuse, but that only means there really is a problem that has to be fixed. It is the reason the fuse failed.
There is another type of cooling fan that has a "clutch" on it. It may be used in combination with an Electric cooling fan. The clutch is fluid filled and responds to air temperature. It is suppose to work really good in hot weather and coast(free-wheel) in cold weather.
Finally, clogged Catalytic converters can cause your problem. Your engine can build up heat because of them, but usually some kind of "Check" light will activate telling you something is wrong.
When you post a problem, remember to give the type of car you have.
Are you bleeding the air out of the cooling system, you must do that or it will get air pockets and overheat.

There are still a number of things that can cause this. Without knowing anything about the vehicle it's difficult to tell. Is this a vehicle that is easily capable of achieving these speeds or is it being pushed hard to get to over 120kmph?I'd try to look for some form of airlock within the system. If you've changed a few components already its possible there is air in the system. Does the vehicle lose water or just get too warm?
This vehicle is easily capable of achieving these speeds. Before the problem started we
AThis vehicle is easily capable of achieving these speeds. Before the problem started we installed a new nudgebar, but it is a modified nudgebar. We knew that the waterpump leaked water, that's why we replaced it. But now we think it's the nudgebar that is blocking the airflow to the radiator.
it does'nt loose water anymore it just get warm.... the heat gage inside the car just rises above the normal level.
