Is Hardin the exclusive dealer for R&D Enterprises T-stat controlled oil coolers?
I did hear from an unreliable source that Sterling gets them from R&D Enterprises but can not confirm.

cp has them KE has them and I think Fred at Trick if my mind serves me right

I just bought some from Fred at Trick Marine. They look great.

I called Trick Marine yesterday and Heath said they didn't carry them, hence my post.

Not "marine" but you can save some money here:

Might try Billet Marine.

I don't think they list all thier products online, so you might want to give them a call.

Just by chance I was looking for a billet mount for my oil filter today in EMI's catalog and saw and oil regulator type piece that bypasses the cooler until your oil reaches 215 deg.. I just looked at their web site and I can't find it but I have a little bit older catalog and it's in there. I would call them and see if they still offer it. It's funny because I was reading about it wondering how it would actually work..........

Insptech,
Are you running those Permacool thermostats from Summit?
If you are how are they working and are you happy with them.

I Have A $39 Permacool And It Works Fine, Oil Temp Stays Around 180 Without A Water Thermostat. Just Not As Nice As The $400 One. Start Adding Russel Fittings And Braided Hose The $39 Goes To $300 Quick.

The Permacools work well, just buy the larger size opening
