big-phil Posted July 19, 2009 Share Posted July 19, 2009 Can I use a trans cooler from Autozone for an oil cooler for my Z? Seems like I should be able to? I want to replace the stock turbo cooler thats on there now. Quote Link to comment Share on other sites More sharing options...
johnc Posted July 19, 2009 Share Posted July 19, 2009 In "most" cases its OK to use a cooler for engine or transmission oil. Some coolers designed for transmissions have internal vanes or fins that create too big a pressure drop for the engine oiling system. This is especially true if a 30W or a 20W-50 engine oil is used.

ckolander Posted July 19, 2009 Share Posted July 19, 2009 How would you know the difference? Seems like this would be a fairly inexpensive solution for all us poor people. Quote Link to comment Share on other sites More sharing options...
blue72 Posted July 19, 2009 Share Posted July 19, 2009 My dad had a stack of good used tranny coolers, and I am using one as an engine oil cooler on my Suburban. I made sure to select a stacked plate cooler with sufficiently large input and output holes. I'm running 1/2" flexible cooler line into appropriately sized barb adapters because I didn't want the cooler itself to be a restriction and possibly raise the oil pressure or put more strain on the oil pump to push it through a smaller orifice. At least that's my hypothetical thinking on the subject. Quote Link to comment Share on other sites More sharing options...

I'll see if I can tell if it has internal vanes. I use only Royal Purple 15w40 Quote Link to comment Share on other sites More sharing options...
