New head gasket, now it's overheating...
Posted: July 21st, 2007, 5:41 pm
Here's some background...
- Head gasket started leaking, oil in water, etc
- Put on a new gasket as well as a new cylinder head (to avoid warp-age)
- Spent some time cleaning things up, replacing some other gaskets, etc
- Replaced most water hoses as well as the thermostat
- Replaced the injector o-rings (just to be safe)
Today is the first time I've started it with all the new parts in place. It started on the third try and ran great. There was quite a bit of HLA noise, but it went away after awhile. There are no leaks or puddles on the ground, no white smoke at all, and the car is running smoothly, even when I rev it a little.
The problem is, it was fine for awhile after it reached normal operating temp. Then all of a sudden, the needle on the temp guage climbed to a little above half. Then it went back down to half. Then up again, then down again. Finally, it kept going up, so I turned the car off. All of this happened at idle (haven't gotten out of the driveway yet). The fan didn't come on, so I know I need a new fan switch, but the temp went above where it should be, with or without the fan. It started pouring rain here, so I had to stop working on it for now.
It sounds to me like there's air in the cooling system, but if anyone thinks different, I'd like to know. Wouldn't want to warp the new head and all. I guess I'm just looking for a second opinion here.
Thanks in advance!
