hey, i'm wondering, if you can help? my 89 jeep cherokee has a vacume leak and recently it started overheating. i don't see any fluid leaking but when it overheats, the engine smokes and i can smell rad fluid. could these be related? any suggestions about where to start first?

thanks for helping me everybody!

I think, I fixed the overheating but now it wont start at all. I'm pretty sure its the vacume leak. there seems to be no air in the engine. where do i start?

Is it turning over but not starting? If you got a vaccume leak it should still start, but rev irratically, it could be a number of things, loose ground strap, fucked up relay,

yeah, it starts but it runs rough, then. engine stops like it's getting no air.:dontknow:

Check the little plastic vacuum hose that goes from the throttle body to the map sensor bolted to the firewall above the back of the valve cover

The expansion tanks tend to be an issue with these things. The caps always leak or strip, or dont tighten up properly, just putting a hoseclamp on the cap, (not too tight) will help keep it on and keep it from peeing

This will help with cooling woes as long as the rest of the system is up to par: http://www.madxj.com/MADXJ/technical/technicalfiles/JTopenSystemSwitch/OpenSystemSwitch.htm

Get rid of that little pesky green turtle of an expansion tank. For my overflow I just used a washer bottle, nothing fancy. Lordco can get the Moroso inline filler.

I found the problems. I had a broken Fuel Pump, Fuel Filter and Fuel Lines. So I replaced them all and now my truck is working fine. So thanks everybody for helping me try different ways to find the problem. My truck is fine now. Thanks![36]
