Ya'all please shut your caps lock off...

I have been battling the same issue for a year. I narrowed it down to my ignition timing. I have a 87 also.

[cartpusher16]

your right just a newbie with some trouble.anyway the gauge is fine.because it gets hot right away in like 3 minutes,hoses are hot and try to open radiator cap it blows all over.what could cause it to get this hot so quick?

[edudley]

thermostat in backwards = no flow
wrong water pump, CW or CCW
Just somethings tocheck

Good Luck

thanks for the pitcure its great how you can get this infomation i could not find anything like this ! yes i do have it installed correct.but jeep still overheats quick like in 3 minutes.looked in radiator fluid moving but some white foam on top.no water on oil dip stick.any other ideas?

[DrLewall]

maybe new water pump is junk? Try it without the thrmostat and see if it runs cooler, if so then thermostat is JUNK..

[Goofatyerservice]

You sure you have ENOUGH fluid in there?

Ya might be the wrong or messed up water pump.... or maybe you don't have the belt on it right...

If it's an 87 they are really prone to being small. So maybe a 6" coil conversion and some 36"s would fix the problem? If not I'm sure an Atlas II would cool it down.

Go here (http://images.google.com/imghp?tab=wi) and type in "jeep thermostat" & hit "enter". Viola! At least that's how I did it..... :D

White foam? Maybe your water pump is turning the wrong direction, as edudley previously mentioned? I've seen that before....

[cartpusher16]

ok will take water pump off and check it or get another one.they are cheap enough.and yes the water level is full.but why would it heat up so fast?

[cartpusher16]

and yes a lift and larger tires will be done.this has been a project jeep.started it from junk trying to get it back in running shape.if i knew how to post pitcures i would.thanks for the help.

Many modern engines that use "serpentine" style belts are versions of older engines that used "V-belts" in their original design.

Pumps that are designed for "V-belts" may turn the opposite direction as the pumps designed for "serpentine" belts in some applications. The vanes of the impeller of one type of pump are angled in the opposite direction of the vanes on the other type.

Running the pump in a "backwards" direction would cavitate the coolant, possibly causing the "foam" that you are seeing.

If there is any question, I would remove the pump, and consult an experienced parts counter person. They could pull 1 of each pump out & compare them to the one you have.

good idea.when i get pump off i will take it in and compare the two.
