Thread: Finally bought an XJ! Cooling issues already hahaha!

I took the thermostat out on friday. It now runs a lot cooler, especially with beach/dune work. Just have to let it warm up good on a cold start

However when u get into traffic for a bit or put it under a bit of load its not long before its back at 100, and climbing slowly till almost the red...

Thanks Taz, Planning to have my radiator checked this coming Tuesday, probably will replace it with Adrad (see pic below, obviously above the normal temp right?). That will be the first step then maybe replace the stock clutch fan...actually interested in installing a thermal fan (should i go with reverse rotation??), quote from this website: http://www.cherokeeforum.com/f2/fan-...p-grade-10269/ "Non-thermal fan clutches engage the...

Where abouts in rocky did you get the adrad? I really need to buy one for mine and swap to dual thermos at the same time.

I put an Adrad in mine, best thing I have done. Keeps it nice and cool.

What make thermo fans do you run junglejuice???? Ive got a 16inch one from Supercheap and it doesnt move as much air as the standard small one on the drivers side.

neddle sitting on 100 is normal. make sure you have a 50 50 mix of coolant and water. the viscus fan is not easy to check, i replaced mine at about 130,000 km. the adrad will help quiet a bit. if you are working it hard in the sand an additional oil cooler on the auto will help as this is where a lot of heat comes from.

First of all congratulations on a great choice of 4x4, you cant beat an XJ and the 95 is best of breed IMO You have done the right thing with the Anrad, it will fix most of your problems, If you want you can run a colder thermostat , if you go too low the computer goes into “Warm Up Mode” and reduces the power from the motor and stops the gear box dropping gears. This defiantly occurs with a 160oF, the standards is 195oF I run a 180oF the...
