Hey all. Searched this one up on the site and found nothing to current. I am a big believer in oil coolers. All the trucks I have use them and they work well as I tow alot. That said, I get the need for thermostatic control and have seen units like this one available> https://www.cantonracingproducts.com/cgi-bin/commerce.cgi?search=action&category=2270 Biggest drawback is they are pricey. There must be an option for using an auto wrecker piece you would think. Any suggestions on a good donor choice would be much appreciated! Thanks.
