My 2005 Monte Carlo is running hot and dont know why?
Changed the radiator, thermostat, water pump, new coolant bleed valves, put in new coolant put on a new sending unit and a new radiator cap. It basically has a whole new cooling system in it. You can let it sit and idle and it doesnt run hot. But when you turn the heat on in the car the driver side only blows out luke warm air but the passenger side blows out hot air. I dont know if something didnt get hooked back up right? HELP!!
Just from reading your post it sounds like you didn't get the cooling system completely purged properly. And there is air still trapped in the cooling system, I personally use a system that vacuums down the cooling system and then you fill it through you vac tool, when your done there is no air in the cooling system. Its the easiest way to do all cooling systems but is a must for reverse cooling systems like your Monte-Carlo. There are several brands out there but the one I use is a Migtyvac brand.
Are the electric cooling fans for the radiator coming on? If not that could be the problem. HTH. -Jim
