just recently my trucks heater stopped blowing hot air and the same day it started having problems overheating. I have replaced the themostat, radiator cap, and checked the heater core which isnt clogged. I was wondering what could be causing these 2 things. Is it possible the heatercore is broken if its not clogged.
Hi: If the truck started overheating at the same time, check the radiator for coolant circulation. With the engine cold, remove the rad cap and allow the truck to warm up. See if you can see the coolant circulating once the thermostat opens.
