I'd say go buy or borrow a cheap infared thermometer (I think I paid less than $20) and see if it's REALLY overheating. It's very common for the electrical system to get screwy. When the guage on mine was pegged on the hot, it was actually only 180 degrees. I have replaced everything but the guage on mine, and I still get erratic temp readings, but it stays around 170 max.
Sounds like you'll need to find the procedure for testing/replacing the thermofan switch on Clarks Garage. If you decide to replace the switch and the thermostat, you can order them from a VW Rabbit if you want a lower temp system. Mine both work together at 160 degrees instead of 180+ stock. If your fans aren't kicking on, turn them on with the AC control like you did before and monitor the temp. If it really is getting hot, you can try bleeding the air bubbles first, then test or change the thermostat before going into the waterpump route.

First off welcome
 Sounds to me like the h2o pump is probably shot and the coolant seaped out and the car was parked. To confirm this fill with coolant and bleed the cooling sysem per www.clarks-garage.com Bleeding the system is important. After this you should be able to figure out where the coolant is going. Good luck! keep us posted

Welcome to the board!
If you determine it is indeed the pump, I have a couple in inventory, I could pass one along for well below list  If you plan on doing the belts yourself and need to borrow the factory tensioning tool, drop me a line, I frequently loan mine out.Good luck with her!! -Nick

400 dollars for a 944 reminds me of SolReavers' sig:
There may be nothing quite as expensive as a cheap Porsche. That said, you've got a heck of a deal if the body is relatively rust free. I'd be willing to bet this thing hasn't had a proper timing belt change in...a long time. If clarks-garage doesn't give you a ping of death when you try to load pages from them, look there to find out all the goodies you are about to get to pay for. Belts, rollers, and water pump--with an honest mechanic--will probably drop you $1600 or more depending on where you live. Which may prove a significant investment on an engine that may be shot (for $400, there must be something teribad wrong.). But you still have to buy that calibration tool if you don't have access to one already. Other than overheating, how does she run? Have you checked the plugs yet? Any of them look like they've been steam cleaned? Any of them blacker than crude? How does the gas smell; is it gone bad/water in the tank etc? I'm sure you know enough about cars to know that blue smoke=bad but a little more info on how she purrs--or if she coughs like a Vegas slotjockey chainsmoker--would be good.

Well the body is 100% rust free. CA car since new...Timing belt was done about 15k ago but who knows what kind of guy did it.
I plan on doing all the work myself...I would like to check the thermostat but that friggen snap ring is like impossible to get out without the pump off the car...I was recently laid off so I have no money for parts/specialty tools but my new job starts tomorrow so I'll be getting money soon... Her engine actually sounds good and theres no smoke of any color blue, black or white. Haven't checked the plugs yet...stilll....ack. I had lent my spark plug socket to my friend and i just got it back tonight. And I've been running her now and then and now the bad gas has been used up. Gonna fill her with fresh 91 chevron and some techron fuel system cleanie stuff... I filled up the coolant resevoir with regular water and since she's been running, it hasn't disappeared... I ran her for awhile and then pulled the lower radiator hose off...the water in the bottom hose was still cold and i wiggled the thermostat a bit and the water in the block was scorching hot, i think its actually stuck closed. I hope. lol. I just can't get the damn thing out, and yeah I definitely need to bleed the system, though I can't seem to find any phosphate free kind, is it really that bad to put regular coolant in? it would be better for me to just do all the belts and the pump, but i want to at least drive to a mc donald's or SOMETHING haha. oh well....gotta wait for $$ |
