ok i recently bought a new coolant over flow resavore and new cap for my 89' wagoneer. to make this story short it ends up over flowing over the top whyle the cap is still on and i end up loosing all of my anti-freeze out of the resavore. im getting the cap tight, but i dont remember it theres a gasget on the bottom of the cap or what but its starting to happen every 4-5 days now so yeah. kinda need help any advise is appriciated.

 

There are some bad caps/bottles that are in circulation right now. The only ones (OEM style) that have been getting a good rap are those being sold by Gerroffroad. He has a page in our vendors section. Good luck, I personally did away with the plastic bottle and went the aluminum route HERE

 

just out of curiosity are you overheating at all.

 

Have you bled the air out of your system. Closed coolant systems usually need a burp every now and then. Other wise you may have a stuck thermostat. Your cap will only take about 16 PSI before it blows the seal on it. Should be a rubber type o-ring gasket in the cap. HTH.

And I personally love the Waggie, nice choice on the new jeep, I know a few 89's had the D44 rear axle was yours one of the lucky ones?

 

Dude that's so cool. It may be harder to tell the level of fluid in there but still would look sweet. I hate plastic stuff on jeeps

 

I think I have two of the bottle/caps oem in my barn. I switched to an open system...so they are just sitting on the shelf.

 

sadly no i plan on finding one though

 

no

 

Let us know what you decide to do.

 

i think im just gonna invest my money in a aluminum one it sounds like a better way to go

 

any overheating? was the coolant boiling when it happens (im assuming yes). if it is, check the system for leaks. they can lower the boiling point of the coolant and thus causing the resevoir to **** out coolant.

 

Sounds like you got more going on here than meets the eye. Why did you put the new tank on? Was it cracked? I would suggest fully warming up your engine, shutting it off and checking for cold spots on your radiator. Might be time to swap over to the newer style open cooling system.

 

when i bought it from my grandpa it dident leave his drive way for 3 years and when i started driving it abunch we reaplaced the hoses and that kind thing. but when we pulled the hoses off the tank there was a crack on it so i ended up getting the one thats on it now

and i will check my radiator for cold spots thanks

 

One other hose related issue. The lower radiator hose has a spring inside to keep it from collapsing when the pump wants to suck too much fluid from it too fast. That hose needs that spring. If you didn't put it back then there is part of your problem.

 

One more question, how do you guage the level?
