When I first rebuilt my daughter's 02 KJ 3.7L V6 engine, I reinstalled the replacement fan that she had bought for it because here e-fan was shot before the rebuild.
I also replaced the CTS after the build. At that time, the e-fan was kicking on and operating perfectly.
I recently replaced the failing PCM and am now struggling with other parts. But that's all besides the point of this thread.
When her KJ is running, it runs for about a half hour at normal temp, I THINK.
Normal operating temp., I believe, is indicated by the dash temp. gauge reading with the needle at 12 O'clock. Is this true or is normal operating temp above the needle's center position. Here's why I ask...
After a half hour of driving, the temp. will climb to the next line between 12 O'clock and the red line. It doesn't ever get hotter than that mark. I'm gonna call that mark "3/4 hot".
It will get that warm, then cool down to "5/8 warm", then warm back up to 3/4, then cool back down to 5/8. Is there a concern here or is this normal for an '02 KJ 3.7L V6?
At this time, I can't get the bleeder screw to turn. At all. I see coolant seeping from it, so I'm assuming air is bled from the system. No matter how much torque I put on that alan-head plug, I CANNOT get it to tighten.
Here are my questions:
1.) Why's my bleeder stuck and how do I unstick it?
2.) Why's the e-fan not kicking on now? Relay?
3.) What is the normal behavior of the temp. gauge needle during normal operation?
Thanks for any help again. I'm not sorry for the long post because I want to thoroughly explain what's going on. I hang out ALOT on the WJ forum somewhere else and can't help folks that don't explain the situation....
