Default 94 civic overheating saga...continues

Still overheating. They replaced radiator saying it was clogged. Still no
joy.

Now saying head gasket.

Any guesses on what I'm looking at for a head gasket replacement?

===========================

Is the radiator and reservoir maintaining their levels of coolant?

Are the radiator fans ever coming on.

If your head gasket is shot, there could be coolant in the oil, white
clouds of smoke / steam coming out the tailpipe, and /or oil in the
coolant.

Above all, make sure your son keeps the cooling system topped up
correctly.

Also, please tell us the symptoms of 'overheating'.

It climbs to the RED, the coolant catch tank is bubbling coolant over. It
doesn't seem to pull the coolant from the catch tank.

Fan only comes on when it's amlost in the red. Okay, probably touching the
red. We keep topping it off. It keeps spitting it out. Fan pulls the temp
back down, but doesn't kick on again until red.

No exhaust smoke or strangeness in the oil as far as what is on the
dipstick.

The coolant in the catch tank seems clean.

Both hoses top/bottom are hot.

I have a similar problem with my 87 Prelude! The dealer said to replace the
timing belt and the water pump. It is not time to replace the timing belt.
The water pump has never been replaced but it seems to work fine!!! Mine
goes to about 80% but never to the red. It usually happens when idling in
traffic. The fan used to come up at 50% and turn on after I shut down the
engine. But now it come on at 80%. I have one eye on traffic another on
the gages!!! I replaced the fan switch but that did not help!!!!!

You said you replaced the fan switch. You mean the thermal switch that is
in with the thermostat? That would be what is controlling the temp that it
comes on at. It's a cheap item, I'd start there. I'm still going to
replace my thermal switch even if it needs a head gasket as I want it to
come on before the RED.

========================

I think we're finally getting somewhere... Your system isn't building
pressure, so you may just need a new rad cap. That's probably why it's
not pulling the coolant back in either.

A presurized system boils at a much higher temp, and having steam inside
your system throws off the fan switch and the thermostat (both must be
emmersed to work, just like an emmersion thermometer) Even your temp
gauge won't read correctly if your coolant is boiling. . .

With the engine coolant cool, open radiator cap and look at the
coolant, is it green or gray? Oil in the coolant turns the coolant to
gray. Run the engine and look for air bubbles...a cracked block or
blown head gasket can blow air into the coolant....I am talking about
below boiling temperature. Is there an air vent valve to bleed the air
out of the coolant on the high point of the engine? If so bleed the
air out of the coolant.

Replaced cap (sorry, left that out).

Coolant is a nice green.

Will check the air blowing in the radiator today.

I think the fan switch is located under the radiator. I do not know where
the thermostat is located in 87 prelude SI but that is my next step.

Check EVERYTHING else before you do the head gasket. This was
happening to my car and I spent $900 for head gasket/thermostat and
that didn't fix the problem. Obviously, it's something cheaper.
