When I did the scenic rim trip with the boys from the patrol 4x4 forum my xj was bubbling and overheating with about 2-3 hours of low range offroad hardcore rock crawling work.

The green machine was working hard with those lockers and centipede 31's.

Jason on here (who came out with us for the day) put me onto a tip of folding the wings
back and down from the vents under the bonnet, I did this mod and found it did slightly lower the temps running around at home.

I did not do this on the day.

However I did pop the bonnet on the day and left it on the safety latch for the rest of the day to get the hot air out under his advice.

So what I have done for mine now is left the main guts of the thermostat in and raised the back of the bonnet up with longer bolts and washers to let it get the hot air out at a 25mm raise and it sits on 70 now no matter how hard I push it.

And I do work the green machine. The bonnet raise gets the heat out.

I am also putting twin GU scoops on the bonnet at the front for more flow.




Worked a treat and dropped it from around 110 back to 90.
