Really? I sold a SRT Charger to get my kit. All the guys on the forum, the first mod they did was to take out the 190 thermostat and put in a 180 to help increase horsepower. They said the only reason the factory put in the higher was to try and get better milage. If I remember, this was also proven on the dino.The general rule is that 220 is the optimum operating temperature. Above and detonation is an issue, and below about 180 and incomplete burn is an issue. In general the sweet spot is about 210.
ford was having problems with the international engines and pin holes caused by corrosion, hence the need to add a coolant additive. the evans beats both these problems. i also added a 210 deg thermostat, heat is what makes diesels roll. so no more coolant additive or having to test for silicates which are what are used to coat the surfaces and act as as a sacrificial metal. if anybody ever puts a filter on their cooling system they will be amazed at the crap that comes out.If you are experiencing a marginal issue with cooling and need to lower the temperature just a few degrees, simply add Water Wetter, or a few drops of DISH SOAP to your coolant/water in your cooling system. The principles are EXACTLY the same in all instances...lowering the surface tension of the water, thereby facilitating a better interface between the hot metal surfaces, and the coolant.
On a side note, other than the issue with the header tank not being in the right place per the FFR design, I have never seen a GTM not cool properly with the stock cooling system and regular coolant. Sooooo, I guess my question would be...WHY? As far as going to expensive, exotic coolants?
BTW- I do believe that all modern diesel engine manufacturers have a specific coolant that they REQUIRE you to use in order to maintain warrantee coverage. Again, I don't see the logic in going to something else.
