I feel your pain Lol I have so much $#!t to do to this heep!! Catalytic converter, muffler, rear man seal, oil filter adaptor oring (again) this thing is killin me lol
i have been chasing cooling issues for a while... surging temperatures... ect
So tonight I replaced the radiator, fan clutch, thermostat, cap, upper hose, lower hose, coolant resevoir, serpentine belt, water pump and inlet tube. Flushed the head/block, flushed the heater core again..
FINALLY!!! I have a steady 200 degree temperature at idle and heading down the highway... and my heat will cook you out of the jeep even at below 30 degree temperatures outside..

First thing i did was ditch my heater control valve that was plumbed into the heater hoses... I capped the vacuum line that ran to the heater control valve.. I bought about 5 foot of 3/4 and 5/8 heater hose... I plugged them straight into the heater core...
Then i got my water hose with a spray nozzle that would press up into the heater hoses... It kind of bevels into a point
Pressed it up to the 3/4 (outlet hose) and back flushed it with the 5/8 hanging over the fender... Then put the 3/4 over the fender and blew through the 5/8 (inlet side)
I did that back and forth untill i had clean water and a good flow...
Then ran the hoses over to the thermostat housing and water pump inlet tube... Measured.. Cut... Install... Clamp
