I usually go in my garage, and then an hour later can't remember why I went out there. Case in point, today I went out to start my electric fan install. To do so, I need to yank the radiator. To do that, I need a catch can for coolant. They were all 3 full, so I needed to put that fluid somewhere. In the garbage can, I find 3 gallon mil containers. I open those to find they BADLY need a rinse first. After a rinse, I am able to then full them with oil/coolant. After doing that, and then cleaning the slight mess I made, an hour had passed, and I had really yet to even start on what I came out to do.
