Markiec - that'll be great mate! I'll PM you my address just now.....

MarksDTM.... Yep, that would be great. I'll swap it for a spare 3.0 one I have here if you like?

Other guys. helicoil is good. It can get you out of toruble. BUT, it is a sort of permemnat fix. When you have something like a plenum which comes off for every service, you want the threads all OK really. hence the change.

Anyone got any other ideas on this overheating? Or just keep flushing away?

[Timbuk]

Its not going to hurt it to keep flushing it Ronnie, especially if Mark reckons its had a recent oil cooler change, you know how much of a pig it is to shift all that crud!!

[nixoro]

Would using more degreaser help in any way?

[CaptainZok]

As an off the wall suggestion, could it be an inefficient water pump, working adequately at high rpm but less so at lower revs? Tis just a guess but may point you in another direction.

[Markie]

job done ronnie re t55 - and i`d flush 2/3 times first - easiest option first....

Hi Mr McB, i would suggest that you pressure wash from the engine side towards outside the radiator fins which should clear the crap off the fins from the condenser and rad. If necessary remove all the fans and do it properly as all the dead bugs dust and crap will restrict airflow. Also the fins get insulated with dirt and therefore you loose the heat transfer capability of the rad. What is the state of the STat?

[RonaldMcBurger]

Stat? Is it supposed to have one?
Stat is Ok as far as I know. I am in agreement with the water pump theory. It will be replaced by default anyway when I do the cambelt at the weekend. In fact, that's 2 cambelts this weeken as I am helping Laidback do one as also.

As the condensor is knackered it can come off completely until I find a useable one. That will ensure airflow!!!! This rad is almost new, so I have no doubt the rad is good and free. I did pressure wash one once. It took most of the fins off!

Problem with the thermostat is getting at it! I mean, the housing is no problem, but the poxy pipe that goes off to the hose is a nightmare as the two halves always weld themselves together.

Anyway, a few flsuhes first.

Theory 2: No names mentioned (Laidback66) Ooooops, that slipeed out...... Anyway, someone suggested the air con compressor may be partially siezed thus holding back the aux belt, which would explain the heavyish power steering and lack of cooling? Mmmmm. If he's right I agree entirely. If he's wrong, what a NUMPTY!

There. A win-win situation.

just a shot in the dark now but how accurate is the temp gauge?

I guess the recommended is to use an aux belt from a v6 without ac although you probably already know this for testing.

[RonaldMcBurger]

Mr Des, good idea and I did wonder myself, but when it gets up to 100+ you can 'smell' it is getting very hot. So I think the guage is correct. It just moves too much, normally they sit solid, this one is up and down from 95 to 100 like a dogs back leg.

Nixoro, You can also use a standard 2.0 belt as that is the same length. I will be popping the belt off anyway and seeing if I can turn the compressor or water pumps by hand.

Didn't know that RonaldMcBurger, learn something new everyday it seems

Certainly sounds like not all the gunge out yet...

Lol.....you would hear that....the screaching of the aux belt would be quite a give away!
