[QUOTE="Anybodyhome, post: 455845, member: 19161"] These funnels and stuff.... ugh... they just take money from people. Okay, first things first. 1. With a cold engine, have someone start the Jeep while you wrap your hand around the upper radiator hose. If you immediately feel coolant flow thru the upper hose upon start, your t-stat is stuck open and needs to be replaced. 2. If you do not feel coolant flow, wait until you do feel it and note where the temp gauge is when it begins flowing. 3. After the engine cools, lift the front end 4-6" higher than the rear and remove the radiator cap. Cold start the engine and begin adding coolant a little bit at a time, taking a few minutes between to allow the system to burp the air out the radiator top. 4. Once the air is burped out the coolant level needs to be just below the cap. Put the cap back on and fill the coolant reservoir to the appropriate level. What you should see if this works is a steady temp gauge. [/QUOTE]
