Question about 1998 Honda CR-V

1 Answer

Coolant guage reading incorrect?

Normal driving,Mac scanner showing about 190 degrees (hooked up to OBD and giving me continuous readings while driving).Guage will read 3/4 up and maybe a tad higher.EVERYTIME I slow down or stop,the guage drops down quickly to around half (more normal) and remains there untill taking off a cruising again where it slowly goes back to 3/4 high.Mac scanner isnt telling me any major differences in temperature no matter if im stopped or not.I do not know if i have a faulty guage,or where the guage specifcally is reading from.Bad ground? Also coolant temp sensor is new.No change in guage performance.

    Coolant temp sensor and thermostat are new. Mac OBD scan tool is plugged in and telling me the engine temp is maintaining around 190 degrees no matter what my guage is reading.

Normal running temperature


I would look else where for the problem unless the thermostat is stuck open. Thermostats work by blocking the water to the radiator until the coolant in the block has reached operating temperature and then they start to open. As soon as they read a cooler water temperature they will start to close and restrict the flow until the operating temperature is maintained . IT would make no difference which thermostat you fitted as the number indicates when it starts to open. I would be checking the temperature sender unit and the gauge and I would be checking the coolant level in the radiator at the cap not the resevoir

2000 daewoo leganza is overheating, leaking anti freeze, and water. what is wrong?


sound like thermostat sticking close.replace thermostat and radiator pressure cap.if already done.you could have faulty water pump.if engine overheating at long slow traffic line or setting at a stand still.the engine cooling fans should be running, check and see if cooling fans running if not,check cooling fans fuses and relays.if all is good,hot wire make sure coolings fans okay.if all is good,code scan vechicle for faulty engine coolant temperature sensor and ecm problems.you need a code scanner where you can check live data check see if coolant temperature sensor reading correctly if engine coolant temperature is 190 degrees the coolant sensor. the scanner suppose to show 190 degrees in temperature if not it reads 80 or 90 degrees the engine coolant temperature sensor is faulty need replacing.if all is good check engine oil if look like milk shake blow head gasket will cause over heating.to be on the safe side i would replace thermostat and radiator pressure cap first.to make sure engine coolant circulating through radiator and engine block.

94 cutlass supreme is overheating,all fluids are fine. I did have someone tell me i need 3 motor mounts replaced. could this be an issue of the car overheating?


Over heating can be caused by a faulty thermostat and or weak water pump and dirty radiator and old antifreeze or the radiator fan now working when at idle but should not over heat when driving. Service the cooling system if it has never been serviced before. Replace the thermostat, buy some radiator flush to clean out the radiator and heater core. Just follow the instruction and replace the antifreeze and make sure it's a 50/50 mix water/antifreeze. If you not sure how to mix it 50/50 you can buy them 50/50 premixed. Water boils at 100'C so you need antifreeze mixed with it but antifreeze does not have the same heat transfer as water so you cannot run 100% antifreeze cause it does not transfer heat fast enough and you over heat. Good luck and hope this helps. Keep me posted, Be glad to help, once you service the cooling system and your still over heating, then we look at the water pump.
