Charge Cooler Update

[FD3UK]

Some of you will know I have done a charge cooler install with the charge cooler rad in the engine bay. I had an AAV fitted on top of the Charge cooler, but it was always weeping.
 
I have now mounted a small expansion tank with bottom feed going to the bottom hose of the rad and a breather running form the top of charge cooler to the top of tank. I have a zero pressure cap on the tank and have left enough head to allow heat expansion.

First impressions are very good, no chance of any air locks now.  Still might have to go for the more traditional method of mounting charge cooler rad in front of main rad though, still get heat soak in still traffic

That is truly a wonderful sight

yup, just the job

Was the expansion tank off the shelf or a custom job? Hope to see it on Saturday (and steal it)

looks really good

whats goin on with the servo hose?looks a bit flat.probly my eyes

What valve have you used to plumb into the PWR cooler to bleed of the air. Or is it just an open one.?? :wave
How did you work out the position of it so that no damage was done to the internal rad.
More pics please of that problem solving bit.  :wave

Hi Rob, yes I just bought one of the shelf got it from HERE I could not make it for that money....   I was very impressed with the quallity. I will have to keep my eye on it on sat. though


Worthog, There is no valve, just a line from the charge cooler tank to top of expansion tank. I orginally had a small AAV there but it was always weeping.

There is a gap between the outside skin and internal air pipes, I drilled a small hole to start with then opened out and tapped 1/8BSPT.

I now have system running on zero pressure as I found before that there was plenty of flow with the cap off but it stalled out with heat expansion pressure build up.

Yes, ref the pressure build up. Thats why I changed to the same powerful EWP that I have for my water pump on the engine. It seems to have worked fine and I am only seeing a minor amount of air in the system due to water cavitation. I just want to sort out a simple bleed system.

Kev looking good .
good to meet you at the Japshow .
what sort of temps are you getting on normal drives ?

[FD3UK]

Sy, thank you, good talking to you as well. On average temps are between 30-40C, but will rise to 60c sat in traffic for a long time I.E. waiting to get out of Santa Pod
