Turbo cooling issues

Howdy, I'm having some issues with my cooling after a price of debris pierced my rad and I blew a hose from the after effects, I've replaced the rad and hoses, but the over heating is still accruing only when driving or in boost. When I'm say at idle it doesn't fluctuate it stays constantly in the "green" I've had the turbo out and can't see any obvious signs of cracking or damaged connectors. My other question is with a big overheat is this enough to destroy the turbo?

Cheers guys

Re: Turbo cooling issues

how far did you drive it with the rad issue ?
after refitting the new rad etc did you bleed the system of airlocks?

Re: Turbo cooling issues

Due to M4 road works I couldn't pull over for about 4 mile :s rads been bled and there's no bubbles or obvious head gasket symptoms. But the oil got fried pretty bad which was fun to swap out.

Re: Turbo cooling issues

if its got hot enough to fry your oil id guess you have cooked the engine so id be getting the head gasket checked.

Re: Turbo cooling issues

Hi guys stupid ? but did you check if your fans are working ? and the fan connectors are properly in on both sides? if this is ok get a sniff test don or a down leak test. you will know if the head gasket is poped all so are you getting any hot air?

Re: Turbo cooling issues

i sugest gettign it to a specialist on the back of a low loader to get fully checked out.

cooked oil is a very bad sign as said and if temps keep rising then need further investigation for definate.

Re: Turbo cooling issues

Cheers T. I've got the engine apart at the moment. So I'm going to do the heads and cam with a shiny new garrett to throw in if it still keeps heating then I won't have any hair left for head scratching! I'm trying avoid taking it to a garage through the stubboness of being a mechanic

Re: Turbo cooling issues

Oh and the fan connectors are fine, the previous owner I think was a bit of a cow boy as every time I work on it I seem to find another unplugged lead. Hopefully tomorrow will be judgement day as I'm going to try and get it all fitted. Of its still overheating then I might have to send it to the yard :s but if anyone's in the Camberley area and wants to point a finger when I'm re plumbing it all that would be much appreciated with beers!

Re: Turbo cooling issues

its always best to diagnose the problem before you start stripping it as your a mechanic you should know that.

you should have don a sniff test or at least a down leak test to see where the air is bleeding out of if bubles are coming out of the header tanks or the rad you would know its the head gaskets

but i suppose its a bit late for that. but do get the heads pressure tested to see if there's any cracks in the heads and may be skimmed in case there warped.

some time it can end up more expensive stripping it down again. Hope it goes well

Re: Turbo cooling issues

even after your rebuild you could have issues..i see you've ordered a new Garret..have you accounted for the remap,when it's fitted??..also if your motor is pre 99 an aftermaket ECU will be needed...

Re: Turbo cooling issues

Cs your defiantly right, If the heads are warped I can skim them myself, motors got a fair few miles on her! So I think peace of mind at least if that isn't the main problem then like I said its time for a RA
