Thanks bruv, you too Cane. I flushed the system a few months ago and replaced the sending unit. I should have replaced the thermostat too.
So this needs to be dealership item only?
Just ordered one with a gasket from the dealership. It's $20something and the gasket is $6something. Ac/delcos are fewer than $10.

I recently found an 88 XJ 5spd 4.0 with about 200k on it that I can get for super cheap, $450. It's got a 231, clean body and interior, and has a factory tire carrier also, two problems
1. It's a two door which I'm not particularly fond of but with the rest of its stats I don't care
2. This is the big problem, the guy states that he cannot keep it running and has replaced the module 5 times because it keeps burning them up (I guess he was hoping he bought 4 bad ones?). What could be causing this and is it fairly easy to fix?

"The Module"?
And dude... You've got Cruiser's Renix Tips in your signature. You're complaining about random electrical issues with a new-to-you Renix... lol

That's what I was thinking when he said module. As for cruisers tips I wasn't sure if they would apply here. I suppose might as well get it preform the necessary refreshing etc. and see if that works.

My temp gauge shows this after it should be warm:
What could be causing this?
My first thought was a faulty sensor, but then I thought stuck thermostat.
I call on the powers of the Jeep community.
Edit: heat was working. But I couldn't tell if it was as hot as should be.

It still "heats up" to about 130, and there she sits. The only time it's gone higher is once when I left the cap off by mistake after changing the coolant, and it overheated when it all leaked out.
