At least leaks with any vehicle (GM or not), that uses DexCool... Leaks are easy to find... Two ways. It's tell tale orangish tint and of course... That sweet smell. Being a GM tech, my trained nose can smell an open cooling system on a GM vehicle a block away.
I've been chasing a leak on the RGC. At first I thought it was engine oil. Now mind you, this is just looking at the eftermath on my salt covered, dirty driveway, on a cold January morning and then taking a quick peak underneath, and seeing a drop at the bottom of the trans bellhousing, leading me to believe it was engine oil from the rear main seal.
This past weekend, at oil change time, I investigated further. it looks like a coolant leak from two lines next to the radiator and runs to the heater that are seeping. I'll end up JB Welding them and see if that stops it. I hope it's not the radiator as I replaced a couple years ago when the seal on the bottom gave way and it poured out the bottom... That isn't happening here. But my point being, the G-05 coolant that this Chrysler uses, goes in very light yellow in aggregate in a tank, and has a very viscous lubricity to it, that is very similar to clean engine oil in small drops/puddles on a clean surface. And of course, no sweet smell. DexCool has that lubricity at first, but quickly becomes "tacky" as you run your fingers together continually and it soaks in.
So one win for DexCool...
