Title: Please Help!!!
Post by: mka306 on 07 June 2015, 12:15:25
I have just started changing filters and checking levels under the bonnet when I found this in my coolant tank...

Oil cooler failed.

Not a straightforward job, as its in the v of the engine under the plenum, and inlet, but most certainly repairable. :)

Thanks for the quick response, I assume this is an expensive part or is it just a pain to fix?

Er, both. Genuine cooler is, I think, in the region of £200??But others will know more about that I haven't done the job for ages.

Might be worth a trip to Stoke to see Daz/Darth loo knee on here. Although it's best not to drive it if possible as it will ump sludge round the cooling system and into the heater matrix, plus oil isn't good for the rubber hoses etc. he might visit?

Worth pm'ing him.

Has the coolant been serviced regular? It can turn acidic of left too long and eat the cooler and cover plate etc. ....or it's just failed.

Thanks gixer, jamesv6cdx sent me a pm when I first joined offering his services and he will come to me, I've pm'd him so hopefully he will be able to do the job.

Thank you very much for the advice it's refreshing to see such a quick response to a worrying problem :y

Totally agree, all I want is the miggy running how it should, luckily the car is off the road until I have completed all the necessary work and some not so necessary, but this is something that needs doing sharpish as I can't risk turning over the engine in it's present state. Now it will need a coolant flush, engine flush, oil and coolant change and of course the cooler unit, must say I didn't see that coming :o

They changed it to stainless steel, but that doesn't alter the fact that the coolant should be changed at regular intervals.

I'm not sure the chaps at Ellesmere Port (many of whom were laid off when 54degree V6 production ceased) would be particularly impressed with you calling them muppets.....
Title: Re: Please Help!!!
Post by: powerslinky on 07 June 2015, 17:34:23
The answer is probably gonna be "never"  . . . but . . . can you fit a used  stainless oil cooler if it looks in good condition ?  :-\

Just asking as the oil cooler was "supposidly" changed less than 2 years ago by the owner of my 3.2 breaker  :-\

I'm preparing for a barrage of flack on this question  . . . but just asking  ;D ;D ;D ;D

Title: Re: Please Help!!!
Post by: VXL V6 on 07 June 2015, 17:45:02
Problem with a used one is that the threads often strip when you try to tighten the two big bolts down for a second time. You wouldn't, of course, lose anything by trying  :)

Short runs also cause the mayo to accumulate in the header tank ;)

Could just need a coolant flush, then run it for a while and keep checking the header tank...

Not always a oil cooler failure that causes mayo in the header tank, could sometimes be one of the HG's is on its way out also.. or in my case - as I recently found out - both HG's had failed LOL

Short runs will cause mayo to accumulate under the oil filler cap but never in the header tank. Only cause of mayo in the header tank is failed oil cooler.
I have changed 2 leaking coolers on late model V6,s so Im dubious about this alleged improvement on the later ones.
I have used a second hand cooler as a replacement, but as said, you need to take care with the thread on the cooler when installing it. Its not hard to cross thread the nuts and strip the threads on the cooler.

Were not the  2.5's from your manufacturing year prone to HG failure though ?  HG failure is a rare occurance as far I am aware  :-\ :-\   

 Looks like a def oil cooler failure from the OP's pics in my book

I find that placing the nut over the threads loose, then fitting the banjo bolt in the cooler to pull the cooler up in place BEFORE screwing the nut onto the cooler, greatly helps the thread life. The cooler can sit a fraction low otherwise, giving a risk of not catching the thread correctly with the nut.

Apologies if teaching egg sucking, but better safe. :)

I will buy a new one and get the coolant flushed out so hopefully all is well. If HG,s need doing then so be it but I'll start with the oil cooler and go from there.

Thanks to you all for the help it has made a big difference to how worried I was earlier today :y

And probably too late in the production run to make much odds to all but the 2003 v6s. As older ones fail, the replacement part should be the latest ones... Which incidentally are now plastic :-X

Nope, very early ones metal. Doubt any cars still have them. Changed to stainless very early in production run.
