Hi,
I've got my car up on a lift and the coolant has finished draining out of the radiator, but the overflow tank is still full. Is this supposed to happen? Should the tank empty w/ the radiator?

Thanks!

Nevermind...asked a mechanic and he said the overflow bottle isn't suppsoed to drain with the radiator. I took it off, drained it and it'* soaking in degreaser now.

Nope. It takes a vacuum in the radiator to draw in coolant from the reservoir. Just pull your reservoir off and drain it and wash it.

Ya...lo. The resevoir is a pain to clean. Coolant is caked on the sides from never being changed. I'm using the needle nosed pliers and steel wool method.

Drain coolant out of the bottle. Spray about 1/2 can of brake cleaner in there...push a rag in, block the openings and shake vigorously. Dump out, add more brake clean and repeat.

Mine took about a full can to be super clean. Then rinse it with tons of water. Make sure all the brake clean and gunk is out.

Wow! I don't think my kitchen plates are that clean, lol.

Literally it took a few minutes. I pushed a shop rag in and sprayed 1/2 the can..swish around so the rag did most of the cleaning. Empty refill and go again. All set..rinse super well. I was happy with the results

Wow. Okay, I know what my next project is. Question though: Is the break cleaner method safe for the wiper fluid reservior as well?
