PAS cooler question...


Mike B

Recommended Posts

Hi All,

 

My car has a (now leaking) aftermarket oil cooler for the PAS system.

It's a louvred system - 30x30cm and it has breached..

 

Would I be correct in thinking that it has breached because the PAS system uses a lot more pressure than a standard oil cooler? (which I think this is)

 

Do you have any recommendations as to a a cooler that would do the job, any that you have used so far?

 

or will a standard oils cooler do the job?

 

:-)

They are under very little pressure and to be honest, if your car is not getting put on a track regularly just take it out and put it in the bin. I'm currently running a 10 row cooler but it's just turned out to be just clutter to me stopping air going to the rad as far as I'm concerned. I'm removing it in a week or do and won't be running one at all.

It gets tracked very rarely, if ever these days, and the pas cooler sat right in front of the mocal oil cooler, so I may try and find a workaround as suggested..

The existing unit is leaking somewhere inside the cooler, hard to see where from..

Thanks for you input as always..

The cooler *SHOULD* be in the return line, and I am sure it is as near 1000PSI would have totalled it straight away, otherwise. Usually two reasons for cooler failure. Junk cooler, or rigidly mounted and hoses or vibration stressing the unit. By *FAR* the beat way on a manual is buy an auto rad and use the cooler integrated into the bottom tank of the rad for the PAS. Track days on tight tracks like that little place in south Wales NEED a PAS cooler as the constant wheel twirling at slow speeds imparts a lot of load on the system and the fluid can boil or the seals in the pump or rack can be made to go hard and fail.

Thanks Chris.. I did not know that auto rads had an inbuilt cooler.. :-O

I have an aftermarket fluidine radiator in her at the mo - so keen to keep it. Sounds like I should get another small cooler to save me replacing the rack further down the line..

I will mount it away from potential stress.. good point.

and I'll check to make sure it is in the return line (pretty sure it is)
