My car overheats even after you drive only 5 kilos. What could be the problem


two liquids regulate temperature i the car - oil and coolant. you need to check both, as you did not bother to think and provide us with manufacturer,model, fuel type and year, only general info can be provided.

oil - check level and change/top up as required, if change required - change oil filter as well while you are at it. change for type of oil required for your vehicle, oil and filters should be changed every 5000km (3500miles) to 10000km (7000miles), this depend on the condition, driving and age of the engine.

coolant - check level, top up f required.

if oil level is correct, and no loss in coolant either, you need to check coolant flow, start investigation if pump belt is not too lose and tension it if required, cannot do that if pump is driven directly from the shaft. check for thermostat problem and change if required, lastly - check radiator flow and reverse flush if required.

if you are flushing radiator - best is to flush block and heating system as well at same time, drain liquid and re-fill with new coolant.

hope this will help you at least a bit - do not forget to vote... :-)

93 GMC Safari overheating. This happened spontaneously. Runs hot very quickly when I drive it. There is antifreeze in both radiator and overflow res, overflow res fills up more after driving a bit. ...


It would appear your thermostat is stuck in the closed position , find where it is on your engine, drain coolant and remove thermostat housing and stat, replace housing(liquid gasket OK) and coolant. now run engine, turn heater controls to hot leaving filler cap off, top up any water to max and replace cap now warm up to temp until fan comes on. if all ok replace thermostat with a new one and new gasket, you could also flush the sytem out at the same time with a hose pipe by loosening one of coolent pipes and flush radiator.

I have a 96 sl saturn. takes half an hour for my car to reach running temp. When i start driving the engine cools down so far, to the point i have no hot air for my heater. I replaced the thermastat, i...


replace the thermostant again this time get a hotter temp thermostant and buy it from the dealer, the other thing is that these cars are known for the temp sensors being bad this would give you the false reading on the gauge but would not affect the heat, if its taaking a long time then i would replace the stant and this time or before replacing the stant i want you to flush out the heater core, remove the hoses from the heatercore and use a water hose to flush water through the heater core, a plugged core will not throw heat or will start to allow water to flow when it gets good and hot to flow through the retricted core due to rust and crud, try the flush first and then try a new temp sensor if the flush helps the heat, hope this is helpful good luck.

Yes it is normal just no hot air


1. When setting the temperature to MAX, blower level to FULL and outside air Vent CLOSED, no hot air comes out after 2-5 minutes?
If YES, when did you last flushed your radiator and is it full?
2. if more than 5 years ago, flush radiator system, instructions are usually in Owners manual. Use a bottle of Radiator cleaner, run egine hot for about 10-15 minutes, carefully open petcock in bottom of radiator to flush out radiator, WARNING, careful as flushed coolant would be boiling hot. As sson petcock is open and water start to flow out, carefully open radiator cap to enhance flushing flow. Use garden hose to fill radiator while flushing until water coming out from petcock is cold and clear.
Once clear, start engine, turn heter full and blower full blast and keep hose in radiator flowing full, leave petcock open until clear water flows out again. Once clear waters comes out, turn off engine,turn off garden hose and let water drain empty radiator. Once it stops flowing out, close petcock snug and put radiator cap on, pull off radiator coolant catch bottle, clean bottle for any debris and dirt. Drain any water, leave bottle empty and put it back onto its place.
3. Fill radiator with 1 gallon (4L) of concentrated coolant, top up radiator until full, fill catch bottle with concentrated coolant, start engine and keep it overflowing until no bubbles comes out and the radiator is fully hot. Once it is flowing good, close and connect everything. Drive with it and keep catch bottle filled as necessarry.
Good luck. Give as vote and good comment if this advise solve youor problem. Thank you.

My subaru 97 impreza overheated on the freeway. I


If the water is flowing into the overflow tank then it is probably running a little hot. It is normal for a little bit to flow into if as the water heats and expands but there shouldn't be enough to overflow the tank. Have you tried changing the thermostat? If the thermostat isn't opening properly this will have all the effect in the world on how hot your engine runs.

Smell the coolant. Is there any hint of gas smell? Also look at oil, any coffee coloring indicates problems.
