Coolant leak... any ideas?

astras · January 31st, 2009, 09:36 PM

So I just got a "new" '91 LX hatch... the car runs great. I put damn near 100 miles on it today and went to dinner. When I left the restaurant, the temperature went up to around 220*. When I drive it though, the temp goes down. At stop lights, it goes back up.

When I got home I popped the hood, with the engine off, and heard a hissing sound coming from behind the intake manifold, on the throttle body side. I can't see where it is coming from, but I don't feel any water coming out of the head on that side.

Any ideas?

Just a side note, I just checked the oil and coolant... There is no oil in the coolant and no coolant in the oil.

how low on coolant?
does it has the clutch fan? look for oil on the clutch....never let it get that high I hope you turned the heater on

Like I said, as soon as I started moving, it went back to normal operating temperature... the hiss was definitely water coming out though. There was a small puddle under the car. I am pulling the intake tomorrow and replacing the gaskets. I will inspect further then.

you don't need to replace any gaskets at this point....check the TB coolants lines..
clutch is bad in fan

check the weep hole on your water pump.

did you check the lines that go to the heater core? they seem to blow on every car that I have had in the passed 10 years.
