![]() it was not uncommon to fail a seal in 600 to 800 hours, normally now they go to TBO without any issue using the OAT compound. DexCool solved the repeated water pump seal issues that existed in the very early days of the liquid cooled engines. This is the second video in the series explaining the New Premium CNC Controller. Rotax also uses a ceramic water pump seal that has no issue with DexCool.įor the most part most Rotax service people are told to recommend DexCool as the 5 year life matches the hose replacement times. In this video Legacy CNC Woodworking Machinery Introduces their New 2020 4x8 CNC Router Machines. GM still uses DexCool and changed a lot of the parts in their engines to solve the issues they had from the late 1990s and early 2000s. Founded in 1991, and has delivered more than 18000 machines to every continent in the world. It is good for 5 years (originally GM said forever but they were overly optimistic) Your Rotax has no internal plastic bits to dissolve in the cooling system, you do have to think about the OEM supplied parts to be sure) The aluminium parts will take on a dark grey appearance after running OAT and I have not seen any scale or buildups even after many years of running in any engines even after multiple TBO times have been reached. We are Legacy CNC Woodworking Machinery designed and built in Springville, Utah, right here in the USA. Take a garden hose and fill it with water and let the water flush out any remaining coolant. Wait so the engine is not burning hot, drain the coolant while the thermostat remains open. Drive the car around at operating temperature. Any company that sells coolant if they label it DexCool it is from the original formula. Fill with distilled water/Dex-cool mixture. (plastic in gaskets were hard hit) Even with that GM still sells its branded coolant with DexCool. Line: AFZ 4.

Legacy CNC Woodworking Machinery is a CNC Woodworking Machine Manufacturer in Springville Utah USA. The issue with some of the lawsuits stems from the incorrect use such as incorrect mixing. We know that there is nothing within the supply scope of the Rotax engine that it will harm however other bits you can't be sure of. ![]() Any water added must be distilled water only and never tap water.ĭexCool is an OAT, Organic Acid Technology as Bill pointed out, as such it must be tested by the OEM on the OEM supplied parts. 104 subscribers Share 2.5K views 3 years ago Legacy Woodworking Machinery. (582 and 912) Clearly if you have the DexCool forming a gel or solid it was not prediluted as it should be. I was involved with some of the original testing of DexCool in Rotax engines. 1 Ended up switching over to Dexcool in this car, I don't think I would do it again, did it by accident (bought some at advance, just reading the 150,000 miles but not thinking orange doesn't play nice with yellow) and got some brown stuff during the switchover changes.
