I have an 94 Integra, I have checked the fuses, the fans kick on, and thermostat is good, but yet when I am sitting at a light or even in Park, the temp gauge starts to move towards overheating, yet when i give it gas, the temp gauge drops, I have checked everything.. If you have any other ideas, please let me know, I am at lost with this one.

 

I assume your coolant level is good or that there's not a leak. Could be a headgasket.

 

yea its probably ur headgasket

 

Have you checked your coolant level?
Are both radiator hoses good?
Have you done a compression test?

 

Check your coolant level. And how did you determine that your thermostat is good?

 

water pump maybe??? Is hit has to rev up a little to stay cool, maybe your waterpump is shot, and it doesn't flow like it should at idle, causing the coolant not to circulate right. Just an idea. I would say new thermostat ($7.00 from advance auto), and check the coolant level.

 

COULD BE COUPLE THINGS BAD RADIATOR,THERMOSTAT, COOLANT VERY OLD OR LOW,HEADGASKET ,LEAKING AND BELIEVE IT OR NOT A RIP IN COOLANT HOSES

 

possibly air in the system also

 

I'm having a similar problem... fans kick on, I have an aluminum radiator which has always worked great, I only have about 500 miles on my freshly rebuilt motor with JE low compression pistons, new water pump, and I just recently put a new thermostat in 2 weeks ago. It jumped up today after 45 minutes of highway driving when i got off the exit ramp and sat at the light for 2 minutes the temp gauge shot waaaaaaaay up... I tap the gas and turn the heat on and it goes right down... I can't figure this **** out

 

I am still confused about this problem, I have changed the thermostat, but i think it's the water pump, so about to change it, also while in there do the timing belt. Hopefully it's not the headgasket.

 

Is your top hose hotter than the lower hose? If it is your thermostat is stuck closed. Replace it and you should be good.

 

try bleeding system first. air in the cooling system will cause coolant not to circulate seeming the water pump is bad. i'm thinking that as you're driving, the incoming air is helping in cooling the coolant. i believe that's why it's not overheating while driving. as you stop there is no incoming air (assuming you have air in the system) entering the radiator. therefore the engine begins to get hot because of the lack of circulation (from air in system). if you had a cooling system pressure tester it would eliminate alot of guess work. it would tell you whether or not the water pump is working, leak in system or a bad rad. cap.

pressure tester:


to bleed cooling system run car with radiator cap off. if you see bubbles coming out of radiator keep running until bubbles are gone. another way is if you have a bleeder valve. it should be located at the top of the upper radiator hose. run the vehicle and crack the valve. if air is present, the vavle should "spit" out coolant in intermittent bursts. keep running until coolant flows out valve. while doing both of these steps, monitor your temp. gauge-don't want to overheat.


if you suspect the headgasket inspect the oil and coolant. when oil mixes with water, it turns into a milky-like goo. if you see this when you check your dipstick or see oil in the coolant-bad headgasket. also if headgasket was bad, your car would run like **** considering compression won't be up to factory spec.

Edit:// just read you already changed the thermo
