Take the cap off and drive it.

 

 

Find a good steep hill and face down it and rock the thing.

it bubbles out the top when its trunning though

 

ive read to put some type of t valve in the line coming out of the top of the rad?

I've read that you should remove the temp sending unit in the back of the head, near the intake manifold. As you fill the closed system the air should escape through this hole. Fill until no more air comes out.

 

If you continue to have problems with air getting in, chances are you have a bad overflow bottle or similar air leak.

ive had to fill up mine (way to many times from my past tense cooling problem) and my engine doesnt have a rear temp sender...

 

i usually just fill it up with the bottle, then take off different easy-access hoses and fill them up and re-connect them... then run it with the cap off for a little bit... (it will boil over after a while trust me) then just cap it and check back over a couple days.

These were the directions I've heard others use:

Park the truck with the back end higher than the front. Make sure engine is cold. Loosen temp sender just enough that air can escape. Make sure there is a rag covering the temp sender and that you are wearing good eye protection, just in case the sender pops off. Now have someone start the engine and make sure they are ready to shut it off if anything goes wrong. Let the air escape.

i tried the t thingy, will get some pics to toss up here. it worked pretty good, i ended up putting in about 8L of fluid. i know there is still a lil air in it, but I'm going to run it a little first and try and see if i can work some more of the air out. hopefully i did it correctly as i had NO IDEA what the heck i was doing..lol but it was fun n e way

 

getting my 30's mounted to the turbines tonight and will hopefully have it up on then by tonight. pics as soon as i can get the camera working on my laptop

An '89 should have a temp sender in the left rear corner of the head. If you don't have one -- what are you running for an engine, 'cause if it doesn't have one it's not stock.

97 TJ 4.0 but she's still renix

 

that temp sender has been adapted into the 97 thermostat housing (or is it an 89 housing adapted... idk... but my temp sensor is in the thermostat housing.)
