My guess is that the engine was having an overheating problem and one way to deal with that is to remove the thermostat to gain some extra cooling.  The over heating could be caused by a clogged radiator or leaking head gasket which can allow exhaust to enter the cooling system and cause it to bubble and overflow.  Also, oil can get into the coolant.

Solution: get a compression test on all the cylinders.  Expect to need a head gasket replacement.

Ok so my 2001 kia rio ran fine on my trip from nor cal to phoenix, az and ran fine for 3 weeks after. I noticed the oil level was very low when I checked it a few days ago and it started to overheat. I put...


Your engine does not overheat because the oil is low. Do you get heat out of the vents? Check the fluid level in the radiator not the reservoir. Due this with the engine cold. If the radiator is low than you have a leak somewhere. Add coolant to the radiator and see if you can see any abvious leaks. You may need to have the cooling system pressure checked in order to find the leak. If the coolant level is full in the radiator than you may have a bad thermostat. If you get heat out the vents than we can assume the coolant level is full and the water pump is working. When the temp gauge is hot feel the upper and lower hoses. If one is hot and one is cold than the t-stat may be the problem. If there is no heat out the vents and the coolant level is full than you may have a bad water pump. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Info on oil gage


The oil gage and the fuel gage both use the same power and voltage control. so if the fuel gage is working the oil gage will work too. The sending unit is mounted on the motor and it gets hot and cold and has to put up with the acids that build up in the oil. this uit with a wire connected to it screws into the engine near the oil filter. The units that work the gage are quite expensive and many peaple just go on without one. I have a trooper and the gage does'nt work on it either and they cost alot and most stores don't have them.

1993 voyager New themastat, new water valve, have heat sitting still, in motion cold air, can stop and rev. up motor get heat again. Suspect autozone (made in china) waterpump.


the problem might be the water pump but unlikely unless your engine temperture gage spikes, the problem might be your heatercore. it is a small radiator in your car to heat up the air, they become clogged but dribre in your antifreeze, you should try cleaning it out first before replaceing anything

1998 Tercel Cold heat to the windshield. Lukewarm out front vent.


Hey,

I just replaced my thermostat in my car due to the same problem. Except mine was a 92. I figured I'd start with the thermostat and antifreeze. Then the heating core. Now I have heat.

But yet I still have no heat on the windshield.

95 toyota camery smells like overheating or oil burning even when engine is cold


Check radiator fluid level. Electric temp gages do not read temp unless there is water present, no water no hot temp reading.

What is the check gauges light


CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

No Heat in 99 Taurus


Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.
