bnewport Posted August 18, 2007 Share Posted August 18, 2007 Finally got around to fixing it this weekend. I spliced the wires in the harness with 14awg wire which looks the right guage of the heaviest wires in that harness (probably the fan motors or head lights), the others were smaller guage. The belts were easy enough to put on and tension with the 90 degree turn approach. There were around 7 wires cut in the harness, some of which must have been the coil wires hence why it wouldn't start. I'm wondering what I can put around the spliced harness to protect it better. I saw a wire hose with a slit down one side at Radio Shack. It's waterproof and temperature good till 275F. I figured I'd put the harness inside that to cover up where I cut off the factory cover? Any ideas? Recommendations? Quote Link to comment Share on other sites More sharing options...
bnewport Posted August 19, 2007 Author Share Posted August 19, 2007 Spoke too soon. The car overheated after 20 minutes of running in the garage and pushed out .5 gallons of water through the overflow. I waited for it to cool down. I added distilled water to top up the coolant tank. The fans didn't come on so it's something to do with the cooling relays or fans. I tried my relay (the big one at the back of the box, 104-01) in another car and its fans all worked fine. I then went back to my car and checked the fuses for the fans, #10 and #15. Both were blown. This must have happened when the wires were pulled in to the alternator and shorted out so I replaced them with another pair of 25A fuses. I turned the car on and same thing. No fans, car heats up. Next is to check the fans actually work and the wiring and thermistor. More later. Quote Link to comment Share on other sites More sharing options...

bnewport Posted August 20, 2007 Author Share Posted August 20, 2007 Fans work, gave them juice last night and then turn. Just gotta check the wiring next. Any easy way to test the thermistor in the radiator? Quote Link to comment Share on other sites More sharing options...
bnewport Posted August 26, 2007 Author Share Posted August 26, 2007 The problem looks to have been air in the coolant system. I double checked all the wiring today from the relay box to the wires and everything checked out. Still overheated :confused: The fans would come on at around 3/4 on the temp and would lower it briefly before it started rising again towards red. Next, I tried bleeding the coolant system and there must have been a minute and a half of steam come out. I then turned it off and put in 3/4 of a gallon of distilled and then repeated this 3 or 4 times until just water was coming out. The car now runs in the garage perfectly at 1/4 on the temp guage. So, overall, the car took another 1.5 gallons of water which means there was a massive air bubble in it. I bought more 15W50 to change the oil tomorrow and put a new filter on it, figure the engine has had enough heat in it now to warrant a change.
