Question type: Maintenance & Repair

Cooling system over heats when cold outside

2 Answers

My 2000 Montana looses cooling fluid and over heats only when cold outside. We can't figure out where it goes but then we have to bleed heads and fill it back out. No steam or sign where it goes. Have had no problem all summer but first day it was cold in morning it messed up again. Please help!

Not going into oil or transmission fluid but why would it only do it when it's cold out
