Alright. I own a 95 GP with a 3100. I have the familiar temperature rising issues that many have after reading through these threads here on the w-body forum. I live in the desert so it is something I'm on before the desert starts reaching boiling points and my engine melts down. Here's a break down of where I'm at.
A)PRESSURE RELEASE VALVES
The rising temperature is due to hot air circulating in the cooling system. Opening pressure valves releases air. Ok got that down to a science. Just wish I had one of those air compressors everytime I have to let it out.
Yep. It's sticking. Had it happen to me the other day. Need a replacement. Currently found low temp thermostats that are rated 160 degrees that are made with larger reinforced inlets. Most are for 3800's and other vehicles. What do you think? $15? I'm not going to replace this thermostat and everything is going to be ok. I have replaced the thermostat a few times already. In fact when all this began I opened it up and someone had clipped the thermostat housing out of the ring and left the thermostat ring in the car. I hope that made sense.
C) COOLING FANS
My air conditioning is dismantled and only the compressor is attached to run the belt. The electrical connector is disconnected from the compressor. Would this alter the cooling fans from turning on? Currently the fans do not turn on even at higher temperatures. Even overheated temps. I did a power check on the battery to both fans. They are functional. This is the one of the dead reasons of why my temperature has been rising near overheating. I would love to get a FlexALite 210 but not with this happening. I'm not entirely sure of how important it is to have the AC system hooked up and running. How intergrated is the AC system? I know one fan on the drivers side is for the temp sensor and the passengers side is for the AC system. Which to me is stupid because I would just love to power them up directly and have them constantly on.
Both relays are new and functional.
E) TEMPERATURE SENSORS
This is where I'm at trying to resolve the problem with the fans not turning on. That and I'm not sure how rational it is to have the AC system up and running. Both of my temperature sensors are new. However I would like to check them with an ohm meter if possible. Does anyone know how to do this? The one in the manifold block has one green wire. The other one by the thermostat has a few wires that run through the fuel injection harness. The one in the block with the green wire has a cracked connector clip that holds it together. I had taped it as tight as it gets. I'm doubting at this time that it is an issue. Yet I would like to know if these sensors are even functioning so I can have the blasted joy of working on connectors and wiring. Still don't have a code scanner.
F) WIRE HARNESS
This is the last thing I wish to avoid at the moment. That and connectors.
