I have a leaky radiator (crazy for a 28 year old CJ7, I know!). I plan to replace it Friday. It looks pretty straightforward- a few bolts and change out a few hoses (though let me know if I'm missing something!)
In reading the forums, everyone says I should go ahead and change the thermostat while I'm at it. I'm a newbie, so I'm having trouble figuring out where that part is (anyone have pictures?) and how hard is it to install correctly. I'm confident the PO did almost no work under the hood for 12 years, so I'm not confident any of the hoses/wires are connected properly at this point (recently found out he just took out the PCV valve out of the valve cover in the back years ago, so there was oil just spashing onto the wires and hoses near the firewall at that open hole).
Also- I'm reading the thermostat may possibly be the reason why my heater doesn't work? It blows air, just not warm/hot air. Not 100% sure how they interact.
Any tips and/or photos for a thermostat change would be great! Thanks!
Another question: Is the thermostat in any way related to the Engine Temp gauge on the speedo? I ask because both the Engine Temp and Fuel Level needles don't work and I have no idea how to fix the temp one (I assume dropping the gas tank and getting a new sending unit is likely the culprit for the gas gauge). If the thermostat is not what controls the gauge on the speedo, any tips on what I should check/fix?
