First post!
So, I've just recently picked up a decomissioned P71 that was an old detective\\'s drive-home. The guy I bought it from picked it up at auction around 97k, drove it for about 6k, until it overheated one day. He limped it to a shop and they told him it was the heater core causing it (quoted $1200). Limped it back home, popped the hood, and his coolant reservoir cap cracked under pressure, causing coolant to spew under the hood.
So, he parked it and cranked it once a week over the last 4 months, until I came across it. Had a neighbor of his walk over and take a look at it. We tried to see if the thermostat would open up after running it and it wouldn\\'t, so we pulled the thermostat and ran it to try and get the blower fan to cycle, which it wouldn\\'t. We wired the motor to the battery to see if the blower motor itself works, and it does.
The previous owner said the thermostat that we pulled out was a replacement, but it would never open up and let coolant through. At this point, I\\'m kind of stumped. Everything else about the car is fantastic. The detective that used it last kept up with repairs and general maintenance, which really surprises me. It seems like whatever\\'s causing this has to have a relatively simple solution.
Any thoughts? |

Welcome and a couple thoughts...
First, you can place the thermostat in question in a pan of water on the stove with a thermometer to see if and when it works.
Second, I believe there should be a thermostatic switch that would tell the fan to come on when the coolant gets hot enough. Look for that and test it. Pull it out, heat it with a heat gun and see if it opens and closes using a multimeter.
Good luck,
Dave |
