You should be fine as long as you bleed it properly.

Speaking of heater cores... My ZJ and another client's 1500 sounds like water rushing through the core (probably cause it is). Any ideas why? I haven't even looked it up but I just saw this and thought I'd ask.

No you wont have any problems bypassing the core. Make sure you try to get the coolant out of your core if you can so it doesnt try to slosh around and leak on the starter or run down into your floorboard.

If it only does it when you first start it then it might be low on antifreeze or its stopped up.

Only at startup for me... yes I have a coolant leak. BUT, for the Ram the cooling system is definitely full and properly bled because I use one of those Airlift systems that sucks down the cooling system and then uses that vacuum to fill it with coolant. It does it whenever accelerating though on this one. Happened after a heater hose replacement.

Airlift or similar is the best... but realistically fill the system, keep the cap off and let it idle till it gets rid of the air bubbles.

Airlift is the best way to bleed it but if you dont have one then pull the front up on ramps fill the system up and let it run til the bubbles are gone.


As for the ram it sounds like its getting stopped up or theres air in the system after the hose replacement

Yup you want the radiator cap to be the highest point in the system.

I bet it's getting plugged then. I just did the timing chain on it (new set of chain and gears was only $58!) So this was after the heater hose replacement...

OH! I know what it is! I saw traces of stop leak on the radiator cap. Ah... nice.

Stop leak will definately do it. Get some white vinegar and pour it in and run it for a few minutes with the heat on high then drain the system then take the heater hose loose from the tee for flushing the system and flush it from the radiator through the system until you get clean water coming out of the heater core. Then take the other heater hose off and flush the core from the tee side to the pump side for backflushing. Put everything back together and you should be good to go.

I actually did a new filter a while ago. Just seen a much more built zj today looked like 37s under it maybe 35s. Either way made me feel that way. If the maintenance slows down just a tad I'd be able to get my lift complete. But the ol' girl just won't let that happen.

The air filter that came with mine was solid and black. Looked like it had 70K miles on it. It was horrible.

Bypassing the core is safe. If you have a 4.0, just make sure you don't plug the lines (connect them together instead) as the heater circuit is the only coolant bypass when the t-stat is closed.
