Re: Leaky heater core? '90 Celica



Does the car run OK? I think the car runs quite well. I get excellent
gas mileage, it seems to run smoothly, doesn't overheat (though the
temperature gauge remains at cold when I'm driving then when idling,
the gauge will slowly rise).

The car sat for about three years and is just now being driven again.
When I first got the vehicle I would see an oil smelling smoke coming
from the exhaust manifold. The smoke seemed to stop after I drove it
for several hundred miles. I would constantly smell burning oil but the
smell seems to have gone away. There are days when I think there could
be blue smoke coming from the muffler but most of the time the exhaust
just seems to be "rather stinky."

The location of the hose...? It is almost in the center of the
passenger side of the vehicle and sits about a few inches from where
the hood would rest. As far as a picture, I can't seem to find my
camera. If I do locate it, I will post a link to a picture.

I also suspected that the heater core may be leaking because I read
posts on this group about windows fogging up when using the defrost. It
seems that when it rains, my windshield quickly get fogged and when I
use the heated defrost, it takes several minutes to clear the
windshield. However, if I use the A/C (on cold) to defrost my
windshield, it seems to not even take a minute. From what I gathered
from the posts I read, this is caused from a leaky heater core (though
I do not smell any antifreeze).

Tomorrow I will check the hose. What should I be looking for when I am
checking it? How should I go about checking it? If I purchased a clamp,
could I try to tighten the hose as a quick "test" solution?

THANKS AGAIN. This is rather helpful. Hopefully I won't need to shell
out $800 for a heater core repair (and if it is the heater core, I'll
be sure to find somewhere that won't charge me $800).

OK? Why did you put it up on the rack? As the other posters state, it
could be something else beside the heater core. If it is the heater
core and you are not ready to replace it. You may be able to clamp off
the coolant hoses going to the core or bypass it.
