overheating EA82

well no wonder it was overheating, the old radiator had more blocked cores than open ones. New radiator in and bloody perfect. Oh well had to try all other options before going the big bucks.

But a question about the 4wd. Is it Bad to run it on the tarmac in the dry? At full lock even in wet,slippery oily conditions it makes weird noises. Would hate to think what would happen in the dry!! 2wd makes none of these terrible noises.

Yes, yes it is bad unless you have AWD.
It should only be used on dirt or something else really slippery or you get something called Binding up happening and this is what you are hearing.

cool, will leave it in 2wd then. is there a thread on here explaining the differences between AWD and the 4wd system on earlier models?

Good to hear mate! Its not a bad idea to try all other avenues that don't cost alot - it also means that part of your cooling system is up to scratch.

The 4wd on bitumen is a no no but can be used in the wet, just watch out as a wheel un-binds the system on the tram lines

I did this just before I put the welded rear diff in and was glad I did - some dickhead hit the anchors in front of me for no reason, if I wasn't in 4wd i would have been in his back seat.

Also, avoid U turns in low range, best to do a 3 (or 50) point turn as a U turn puts a lot of strain on the gearing somewhere and eventually something snaps...

both AWD and 4wd have drive to all 4 wheels,or more correctly to both front and rear diffs, as you may guess.
AWD appears to now be a term associated when a 4wd system has another "DIFF" the centre diff between the drive of the front and rear diff.
This centre diff allows different torque between front and back, thus allowing front and back travel at different speeds.
So the 4wd can be engaged allways.
Oh you may just now be thinking, oh that might not be so good on loose surface, and your correct, a real 4wd with AWD would have a centre diff that can be locked.

well after a big long trip to test it, just as i arrived home i smelt coolant. SHIT. the hoses running around the inlet manifold that i "fixed" before. One has burst and was pumping coolant out like a mofo. Couldn't be arsed pulling the inlet manifold off to get to them so took it to the radiator bloke and he did it. Hopefully it all sorted now! otherwise i'll be broke.

I think there are a few here who get sick of saying get the radiator cleaned properly, not just a flush. It is a common cause with cars in general that get warmer than wanted.

These 4WD boxes in L series do not like turning much at all in 4WD. If on dirt and need to reverse and turn I shove back into FWD to avoid diff binding. Then back in 4WD for more straight driving

Yeah already got a new radiator because the old one was even beyond coring. Just these little hoses decided to cark it, i guess just because they could.

I have seen these original hoses last twenty years, that ain't bad. Always expected to see them give trouble at about 13 years. Hang on to your car for next ten years and see if these newies leak before then.Money well spent

Keep an eye on the rest of the cooling system - you may find there are other weak links ready to let go...

Good to hear you've got it sorted again.

well i think theres only the top and bottom radiator hoses left! At least those are easy to get to:)

Now for some driving!
