Re-Cored Oil Coolers

Great News for owners and operators of Rotary-Wing Aircraft...

F.A.A. Approved Repair Process by Pacific Oil Cooler Service, Inc. Returns Non-Serviceable Helicopter Oil Coolers to New Condition - For Far Less Than The Cost Of New (And With Twice The Warranty Of A Factory New Oil Cooler).

Replacing your oil cooler's core-matrix with a Factory New part is a dependable and highly cost-effective remedy we offer for aging and / or leaking oil coolers.

Please see the Oil Cooler Re-Core Eligibility List (below) for current applications.

The Industry Standard for repairing old, leaking oil coolers used to be epoxy applied directly to the area of the leak (although at Pacific Oil Cooler Service, Inc., we have never used epoxy to repair a leaking oil cooler - we perform all repairs using only an appropriate Inert-Gas type weld).

Of course, if an oil cooler had too many leaks - the only option was to scrap it and buy a new one. As for the ones repaired with epoxy, their in-service future would always be one of unreliability because the epoxy patch would (in every instance) eventually fail - or a new leak would soon appear elsewhere within the oil cooler.


When we Re-Core your oil cooler we completely disassemble it and install a Factory New core matrix - the 'heart' of the oil cooler. Your cooler is returned to you as an F.A.A. Approved Repaired Component, with Zero-Time (form 8130->3 furnished upon request).


Your Pacific Oil Cooler Service, Inc. Re-Cored oil cooler is covered by a Two-Year / 4,000 Hour Warranty - that's twice the warranty period of a Factory New oil cooler.

Pacific Oil Cooler Service, Inc. has Re-Cored oil coolers in-stock ready for immediate shipment - or we can Re-Core your oil cooler for you. Please see the Re-Core Eligibility List below for applicable helicopter models and part numbers.
