Possibility of a Thermostat, 1st step for me is to make sure that the Radiator Fans are coming on when its overheating. This will all the electrical part of the problem go away and then you can focus on mechanical parts. If the fans work, replace your thermostat. But make sure you do not remove it when the car has been running. Let it cool down or do it in the morning time.

Slow warm up?


If your thermostat is stuck open it will overheat within 40 minutes or so of running, if it is stuck closed it will over heat within 20 minutes. However your spring in the thermostat is weak and opening too often at too low a temp, all you need is an normal new thermostat and you will be good, and yes you can get a thermostat for your car that will open at a different temp. I would go with 190 if you were to go that route. however your temp gauge will read hot too

Hi, my name is Jose and I have a Hyundai Sonata 2006 V6. The problem is overheat but the water and coolant recipient is full. It seems have something to do with the fan, because when the indicator is over...


Jose, the problem you describe could be caused by multiple problems.... and to go into each one of them here would be an excessive undertaking. #1, check the coolant level in the radiator itself, just because the coolant recovery resevior is full, doesn't necessarily mean the radiator is full.
#2. Thermostat could be sticking closed
#3. The engine coolant temperature sensor could be malfunctioning.
#4. The cooling fan might/could be manfunctioning
#5. The cooling fan relay could be defective
#6. The cooling fan relay is controlled by the PCM (Powertrain Control Module) which might be the cause of the overheat problem.
#7. The radiator could be clogged/restricted.
#8. Head gasket leaking combustion chamber hot gasses directly into the water (cooling system) jackets.
... and the list goes on and on.
Best advice is to take the vehicle to an authorized Hyundai Service Center to have it properly diagnosed. This way you'll know EXACTLY what the problem is and what is will cost in parts & labor to fix it.

Hope this helps

My bmw 323i overheats about after 2 hours of driving my heaters work and i dont know why.


check if thermostat is stuck open as too much flow can cause this. start car cold and see how long top radiator hose takes to heat up. shoud stay cold for 3-4 minutes.
if thats ok check thermo fan operation- run can in drive way at idle for 20 + minutes untill fan starts, keep an eye on temp guage.

2001 hyundai sonata 2.4 dohc, cylinder 3 misfire code


tried testing the igniter also i would look into the injector, that will cause a single cylinder misfire and probably is your problem?misfires are not noticeable at higher speeds, which im sure you know but i would go that route, could have a pinched injector or a stuck one. one easy way to test is swap 3rd injector with another and see if that one starts misfiring instead, another rought is to get a cheap auto stethoscope and put it to each injector to hear if its opening and closing, compare with others. good luck.

Bmw 316i overheating


Also check the radiator cap. If the spring in the radiator cap is worn, it is not pressurizing the cooling system properly and therefore it will cause the vehicle to overheat. This is often overlooked and is a cheap repair. Every additional pound above atmospheric pressure that the cooling system is under causes the boiling point of the coolant in the system to raise 3 degrees F if memory serves me correctly. So, if the cap is old it will boil at 212 instead of 230 (for example)-and cause the system to overheat--even though everything else in the system is new/operating perfectly. If this is not your problem you may want to check to see if the cooling system itself is, indeed, holding pressure. You can get a gadget that fits on your radiator from any auto parts store to pressurize the system--after you pressurize it...leave it alone for about 20 minutes and see if it maintains pressure. If it doesnt, you have a leak somewhere. Hooah.
