If the coolant is below a certain level, the temperature sensor will not read anything and the temp gauge will not rise. Replace the cap, and check that you have enough coolant in the system. If this does not solve the problem, you will need to test/troubleshoot the coolant temperature sensor.

I have Hyundai Elantra GT Manual transmission, the Temperature gage keeps going all the way to high yet the engine is not over heated, and once I change gear the temperature Gage drops to normal and t


Changing gears and the temp gauge have nothing in common. First, check the coolant level. If gets low an air pocket in the engine will cause the gauge to go high, then back to normal. Next would be to check the wiring. could be the gauge/sensor wire is shorting to ground.

Pushing anti-freeze out the resevoir. Changed water pump, thermostat. Temp. gauge does not indicate overheating. Fans seem to be working OK.


Try replacing the radiator cap. A weak cap will allow coolant to leave the radiator and go thru the overflow tube to the reservoir.

I am not getting any heat in my car and it was warmed up. The tempature gage is rising high. What fluid is low? I also, have a leak of something on the passenger's side coming out of engine, it is clear...


Sounds like it's low on coolant. Check radiator. If low on coolant, heater may not get hot & temp gauge will read hot. The leak could possibly be a coolant leak..? Anti-freeze has a distinct odor when leaking from a hot engine. If that's the case, find the leak and have it repaired.

Heater blows cold, temp gauge rises 1997 Camaro Z28, 50,000 miles...Florida, freezing in NJ Car just started blowing cold air today...always smeeled anitfreeze...always has water level light on as long as...


heater core is probably what was changed,..a little radiator under the dash that the hot water runs through and a fan behind it to blow at it thus giving you heat,...pretty much thats it in a nutshell,...sounds like something still leaking under there, (anti-freeze smell),... fill it back up with anti-freeze (non-toxic type so you don't polute) and drive to where you gotta go,....go to your mechanic to find that leak,.good luck, and do a hole shot for me! thanks, cracklin joe
