Help!! I am smelling a coolant on my 90 Civic EF sedan like if it were leaking but I can not find were it is leaking. It seems to be coming from were the intake manifold is but when I check my hoses they all seem to be fine... When I get under my car I notice that there are water marks all over my cat converter.... Any advise on what i should check???

 

Hoses at thermostat?

 

No i checked the hose but nothing seems to be torn and when i check them to see if they is any moister on them they are dry

 

The small lines going to the iac.

 

I will have to check those.... Also idk if it matters or not all this started happening after i change my head gasket

 

Maybe the orings on the pipe that connects water pump to thermostat housing or there's some hoses that go to or from intake. Did u use a new intake gasket and a good head gasket?

 

How many miles ago did you change your headgasket? You may be burning residual coolant off of the motor if just changed recently.

 

Yea I used Felpro gaskets from Autozone. And I did the headgasket about a month ago

 

Does it leak when you run the engine at idle?
If so, try wrapping the hoses with paper towel.
Start the engine for a little while and the paper towel will get wet where there are leaks.
Good way to find pin-holes.

 

I will have to try that today that's a good idea
