I have a bit of a problem, or so I think. I own a 92 civic h/b and recently after driving for about 10-15 minutes my engine temp. gauge goes almost to the top and then falls again and keeps doing this all the way to my destination. Usually when I drive the needle is almost at half way. I've even tried driving with the heat on and nothing seems to help. Any suggestions of what this might be???? Thanks!

Engine coolent leaking?

have you check your coolant level?

Check coolant level. Is the radiator fan coming on when the temp rises? If not, could be the fan switch. Could also be thermostat stuck in the closed position. Get it fixed asap, driving in the red zone can cause alot more costly problems. I'm surprised the heat on didn't help, thats what I did when my fan switch died.

my sis's accord had the same problem with the temp rising and falling and it was the coolant like they said above

my friend just fixed the same problem last Fri, solution was to add coolant to certain level since he doesn't have any

Thats what my problem was, i just got it fixed yesterday.

temp sensor or themostat.. or coolant level .... if the thermostat is faulty and not opening at the right temperature it'll let the engine get too hot ....

but yes check the easy stuff first and thats coolant...

also if you have to refil the system make sure you do it properly and purge the air out of the system... (there is a bleeder screw for that)

if you need help I'm willing to give you a hand this weekend.

Gatherer: Im not sure on 5th gens that we have bleeder screws? If so where is it located. I asked someone and they mentioned it was self bleeding design?

Buff 'n Stuff

1. Check coolant level
2. Check for coolant leak (internal & external)
3. Have rad cap tested
4. Have coolant temperature rating tested
5. Have cooling system pressure tested
