Hello all,
Some of you may remember I had a fault with my EAS-basically after driving for around an hour it would go into fault mode-( when code read it was to do with the pressure switch attached to the driver unit-pressure switch reading issues).
Before I went away at Whitsun I drilled quite a few holes in the EAS cover to aid airflow and cooling over the driver unit.
I had no problems at Whitsun.

Just come back from a fortnight away towing the tin-tent and again no issues whatsoever (what a superb towing vehicle).

So it appears that the extra cooling has worked (must still be a problem with the driver _ MOSFETs getting very hot-but the extra cooling seems to have worked).

All the best

Steve

It seems to have worked on mine too, there are 3 transistors, 2 MOSFET's some diodes and a diferential amp for each solenoid, could be any of those becoming temperature sensitive:)
 
This could be a nice tweak to do as a precaution for others as well. Simple question any pictures on where did you drill these holes? (Patterns on the cover)
 
I guess you drilled on the sides of the eas casing??
If not , why not just remove the lid/cover??
I´m about to get my eas working again so I´m trying to soak up as much info. as possible to get things right :)
 
There you go.

Datatek, did you drill any holes in the main box or just the lid? Just i'm going to be replacing my valve block next week so was thinking of copying your drilling and if you have drilled lower down then whilst the block isn't in I can drill lower down.
What do you think?

No need to drill lower down, if you look there are 2 large slots on the side nearest the wing.:)
 
Morning all,
Should extend the life of the compressor as well as its sucking in cooler air and denser air.

If u fit some fine pattern net on the inside of where u drilled, then it would prevent bugs and small seeds and other rubbish to get into the box .
 
hmm, there should be some suitable net around , but I´ll do "your" drill pattern asap. and try to solve the intermittent jam of the fan under the glovedept. and this and that and ......

But The p38 still is a classy ride :)

What about installing a fan in the lid, wiring it from a live in the EAS block?

I was just thinking something like that
So it comes on automaticaly when the pump is running
Could even go the hole hog and run some ducting from the air box (post filter) so it runs in clean air too!
Or is that just been silly lol

The part that I find gets hot is the cylinder of the compressor and thats lower down and the holes in the side dont seem large enough for sufficient airflow to cool it especially if running in temperatures of 35 c + so i will drill one hole in the front of the box to get airflow past the compressor cylinder when i get a chance.
 
I drilled quite a few holes in the cover directly in front of the compressor as well.
As long as the compressor filter is changed regularly there should not be a problem.
There must be a tremendous amount of heat build up in the EAS box-the only standard ventilation are the couple of slots in the box.
I'm hoping that the compressor will run cooler and thus extend it's life as well.

My compressor was always too hot to touch I changed the EAS driver module and drilled the holes/fitted the fan at the same time. Since then I've checked the compressor after a long run a couple of times and it's never more than warm to the touch.
