Cooling system doing my head in

Bob696:
Thanks for the input guys. Not thought of a baffle (yes got the allisports intercooler) so will give that a go. I have a water pump to fit as well as a leccy fan. I was hopeing to solve the problem before my hols but I will probably give myself more time after the hols and do most of it in one go rather than fafing around.

Vinnie, was it on the tresure hunt you saw me or as I went through kiddy on the way home on sunday?

drmike:
Have you fitted a thermostat yet?

I had the self same problem and fitting the correct thermostat solved it. There was no stat at all there but you do need to get the right one.

Cheap too.

That sounds exactly like my problem :P
Do you have a picture of your baffle :?:

Can't get a good picture at the moment. But it is just a bit of alli riveted to the fan cover and then has a rubber seal strip along the edge sealing it against the rad. The edges of the alli are then silicone to the fan cover to seal that.

Try speaking to Jeremy Fearn Tel: 01629 732546 I believe his intercoolers come with this modification.

Ollie:
Bob,
I had a chat with a chap from Allisport at Billing yesterday. He see's this type of problem all the time, and assures me it's a blockage in the rad :!:
He suggested flushing it out/using a rad clean to try and shift it.

Looks like the reduced air flow shows up rad issues that have always been there, but didn't matter until you/I fitted the intercooler :shock:

Cheers
Ollie

KevinStorr:
Here are some pics of the baffle as good as I can do with out taking a part.



The highlighted area is the mod which blokes the hole which your small landrover intercooler once occupied.

Flushing the rad can help if it is blocked. but if you have a gaping hole the the fan to suck air in from which is an easier route rather than through the intercooler and rad then thats what will happen.

As the guy from Allisport said the intercooler reduces your air flow so you need to get the best from the air flow you have.

As I said before J Fearn is well respected in the performance upgrade department on landrovers and his intercoolers come with a baffle to fit for the reason above.
