Thread: Radiators, intercoolers and exhaust wrapping

I wouldn't pull the radiator out just yet.
When you are changing the intercooler, allow some time to clean the rad fully, as you will then have good access with it still in the car.

Sorry for the OT. Allan, could you better describe the fuel pressure problem, even in PM if you prefer, thanks.

Howdy - thought I'd jump onto this one as I seem to be having a similar problem. A little while ago after very muddy trip out with the boys I experienced loss of power and then overheating. After returning home I gave everything a good clean but failed to get a decent chunk of mud on the back of the radiator which Land Rover Geelong subsequently found for me and cleaned out. Today however I got the same symptoms; air-con started blowing hot air, loss of power, and then temp gauge heading north. After pulling off the side of the road for a bit I resumed my journey (at 90kmh) and managed to get home. No engine warning lights or anything. Any thoughts on what may be the cause if the radiator has already been cleaned out?

By the way it's a 2009 DCPU Puma with about 65,000kms on the clock.

G'day Jono,

If memory serves me correctly, my air con was still working - but I shut it off as soon as the engine went into limp mode (when the temp needle ascended)....so we may have different problems.

I'm going to get in and give mine a serious clean out when I have the intercooler out and will see if that helps. I guess I won't know until then.

I shall start using the seed net and wading cover too - I need to be far more disciplined with that.

Mine had about 55,000km on it when the symptoms started - I'm still wondering if it is a thermostat problem as my radiator was clean on the outside. Aircon worked great ( 48 degrees outside) - in fact the temp rise was more with the a/c off, the fan must have added more air to the cooling than the hot air given off.

At the 50,000km service, they changed all the fluids including the coolant, never had a problem before that.

Hmmmm..... on both occasions where it was particularly bad it was close to 40deg outside and I had a full tank of fuel. Not sure if the full tank had anything to do with it - probably more the heat I'm thinking as I did the same journey today (high 20's) and no problem. Oh well - its in for a service soon so hopefully they can sort it out once and for all!

Has anybody had the insulation wrap on their engine pipe for a few years now?

I was speaking to an exhaust shop owner today, and he warned about wrapping mild steel exhaust pipe, saying it can fatigue and fail, in as quickly as 1 year!! I bought the wrap to do mine, but not sure now. He said ceramic coating is a better option.

I'd like to hear anyone 's comments here please?
