On my 2002 Suburban 4wd 5.3, the aux cooler that sits in front of the radiator is leaking. Rust finally got to it. I did a thorough clean of it and the lines. The lines seem fine. Problem is that they are an all in one set up. I haven't contacted GM and I can't find anything on line. What are the thoughts here about fixing this problem. FWIW, its just seeping now. TIA!

 

Well, its not the oil cooler. Its the PS cooler??? WTF? New one on me.

 

You can cut the lines and connect an external cooler with hoses and hose clamps.

 

Ordered one from Autozone today. $20. Vs the 100 the dealer wants.
