njresler 14 Posted September 6, 2016 Share Posted September 6, 2016 Anyone try lowering engine/coolant temps using additives like Lucas super coolant or Royal Purple's purple ice? Link to post Share on other sites
Retired old Gearhead 201 Posted September 7, 2016 Share Posted September 7, 2016 You don't want to have this engine running cooler since it is most efficient and clean inside when running at correct operating temp. Link to post Share on other sites
njresler 14 Posted September 7, 2016 Author Share Posted September 7, 2016 Ok. I was just hoping to correct the high temps that are not good for the junk plastic they used for the coolant tank an who knows where else. Also thought it might be better for the engine. Link to post Share on other sites
Erik Gonzalez 3 Posted September 8, 2016 Share Posted September 8, 2016 This is why you have dexcool the pink coolant it helps prevent the ware of plastics as I understand Retired old Gearhead 1 Link to post Share on other sites
Mr.tozzi 66 Posted October 31, 2016 Share Posted October 31, 2016 Dexcool and water nothing else. If it overheats with the factory recommended stuff, there's something wrong with it. Retired old Gearhead 1 Link to post Share on other sites
Retired old Gearhead 201 Posted October 31, 2016 Share Posted October 31, 2016 (edited) Erik and Tozzi are both 100% correct..don't mess with the coolant. The coolant tank is another issue altogether...a week point at the entrance of coolant metal tube that expands and contracts and may cause failure at the thinnest point just under the tube..a small square indent. Changing coolant type will kill your powertrain warranty as well as mess up... well, ..you get my drift. Edited October 31, 2016 by Retired old Gearhead Link to post Share on other sites
