Well I got a little update. Yesterday I went to the steel yard to get some material for a back bumper and the jeep must not have liked that idea, because I started over heating. I limped it to the steel yard after letting it cool off for a while, got my metal, then parked in a big parking lot down the street and called AAA. Once I got it back to my place I changed the thermostat but I flushed the cool and system first. I've never done anything with a tstat or flushing the system so I figured I'd take some pictures and do a little mini write up for those other guys like me.
First thing I did was pull the old thermostat out and then put the housing back. I took the one out because it was stuck closed, so flushing wouldn't have worked too well with it not circulating
The thermostat is located at the front of the engine, just below the valve cover. You unplug the coolant temp sensor, and then unhook your hoses (be ready for some coolant to spill out. Mind had already boiled enough out that those hoses were pretty much dry.) and then it's just two bolts that hold on that housing.
So I took the only thermostat out and replaced the housing. Then I cut the upper heater hose and inserted a T coupling to allow a point to attach the hose to.
I thought I got a picture of that, but I guess not.
You take off your radiator cap, and in the flush kit comes this little extension that is supposed to direct the flow of water out of the engine bay. But I used my old upper radiator hose to help it clear everything.
Next you wanted to turn the hose on and check to make sure you don't have any major leaks. If you're all good, keep the hose on and then turn on your engine. Let it run until the water coming out is clear. DONT TURN ON YOUR ENGINE WITHOUT THE HOSE RUNNING! Unless you want to do more work
When I started out it was chocolate milk coming out as you can see above.
When it cleared out I turn the water off and needed to drain the radiator so that I could put the new tstat in and then fill it up again. Well I didn't wanna play around with the pitock valve, so I decided it was easier to get to the lower radiator hose.
To take that off if the radiator I just removed the air filter box. There are two bolts and one nut at the bottom of the box, pretty easy to take off but I took pics anyway
With that out of the way I was able to disconnect the hose and let it drain.
I put in the new tstat and cleaned up the
Surface of the housing and the front of the head before putting the new gasket and housing on.
Then buttoned it all up and put a gallon of antifreeze in, and then filled the rest up with water. Went for a test drive and let it get up to temp, and she's good to go!
