Howdy, I'm new to the forum. I picked up a 2000 T-190 last year because we are building a new house on a hill and I want to do all the land scaping myself. I was working with the T-190 last week and noticed that engine coolant is blowing out the sides where the radiator fan blows out. It is a very small leak somewhere under the radiator, but I can't seem to find it. Looks like I can lift the top cover, lift up on the oil cooler, and then see the radiator. It all seems to look normal. I think that my next step is to pull the radiator and have it checked out. As long as the system is drained, I plan on switching to a less expensive Ethylene Glycol versus Propylene Glycol. Any adivce on where or how to find this leak? Any advice on switching to Ethylene? Thanks!
