Over heating
I have a 1994 2.5 wrangler. I am overheating and boiling over in a matter of 5-10 min of driving. I have replaced the radiator cap ( because its easy and cheap). My hoses appear to look fine. I am planning to look at my thermostat next and then my water pump. I would appreciate any opinions and suggestions. Thank you

welcome:wavey: both possible culprits,leaning more thermostat. when waterpump goes usually blows lower radiator hose. if u have some cash do both at once since they are similar jobs in the same area.also a good time to change gooseneck for therm. mind torque spec. the castiron therm.housing likes to snap if overtightened...

one thing to check is what does the radiator look like inside? does it look gummy under the radiator cap? i had a jeep the kept getting hot and had a good thermostat and water pump and i put a new radiator on and it fixed the problem.

Honestly I found a piece of the fans plastic funnel inside and it was pretty dirty inside.

Flush it all to include the heater core by disconnecting the two hoses and go straight to it with the garden hose. Once everything is cleaned up and looks good to the eye try it with straight water.

That sounds simple enough. Do I need to use distilled water when I run it again?

No distilled water required. Just use the house hose and fill it up if everything is good drain the radiator and add the anit-freeze.

It sounds like your thermostat isn't opening. I would replace it.

This is all good advise. My first day off I will replace my thermostat and flush my radiator. I will let you know how it turns out!

I changed the thermostat and flushed my radiator and it worked, I'm not over heating anymore. Thanks for all the help!
