Has anyone heard of or used a Fleece Coolant Bypass Kit? It helps the coolant to circulate when the thermostat is closed, and helps to pull the coolant from the back of the head when the thermostat opens. I was thinking strongly of making a purchase. Thanks in advance,

Seen a couple pics of it and it incorporates another t-stat into the system....I don't personally like anything more than necessary that could potentially become a problem....like the second stat sticking closed, if it were to ever happened.

Motorsport Diesel offers a bypass kit as well. Not sure of the price right off hand, but Shane (I believe is his name) makes good quality stuff. Might check them out and compare.

 

I got Wicked Diesels coolant by pass a few years ago. High quality parts and it definitely flows coolant because the valve box is HOT after driving.
