Overheating 95 XJ

Post by Jeff in WA »

Hi

Have a 95 XJ, put a new radiator and thermo in it, and it now boils as easy as pie. The block was flushed. Even with the thermo removed it still boils. What did I do wrong?

Hope someone out there as ideas.

We took the thermo out, still the same problem. The viscous fan is okay, the thermo fan is okay. Headgasket has been checked.

Might just sell it. Pity it's economical, drives nicely, does everything right, bar the overheating.

The Jeep guy who fitted the radiator supposedly has done this, but ...... perhaps we need to get it done by someone else to make sure.

Gauge gets to half ....... but the overflow bottle flips it's lid and water gushes everywhere. We get the full gurgle noise, steam, top radiator hose sucks in ......... then we sit and have a cuppa.

Sounds like the cap is falty

The radiator cap hold a certian pressure in the cooling system (its writen on the cap) the higher this pressure the higher the boiling point of the water.

May be u are boiling over at 100c instead of 120c, so may be its not really over heating its just boiling over.

But its not your problem to sort out take it back for them to fix.

Radiator caps - we have bought two different ones and it still overheats. We took it back to the garage who fitted the new radiator - they want $240 to reflush the block!! I'm thinking we should just get rid of it!! We had to buy another 4WD to go bush in.

Flush the block yourself just drop both hoses and take the thermostat housing of take the thermostat out and hose it out its only 2 bolts for the thermostat housing just get a new gasket lots cheaper than what there quoting to flush the block man thats a rip off

Take your time & make sure you purge all the air out of the head. You must have a air pocket & trust me have had the sme prob your having now when I did my motor swap. Darn thing would boil up FAST! Get the air out & have it back on the road.

Check the water pump is ok.
Check the belt is correctly routed (not kidding).

Yep definatley check that belt, it goes all over the place (did mine today) and one mistake and you'll have the water pump spinning backwards and doing nothing at all, it would certainly cause it to verheat big time.

Cheers
