Heater problem V8 Four Wheel Drive Automatic
My Silverado is the 5.3 newer body style how do I remove the heater core? Step by step with photos if available Our truck is a C1500 Silverado 4 x 4 with the 5.3L engine. The 8th diget of the vin is a "T" as in Tom. It has 131,000 miles on it and I don't know if it is original but assumed it is.
The reasons I believe it needs changed is.
I have no heat so I checked the following.
I have inspected the modulator motor and shaft that controls the baffle for movement and the do move. I turn full hot and it moves, fully cold and it moves and medium heat and it moves half way back.
I have also checked the temp guage of the truck while running and it runs in the area of 200+ deg-F. And stays there.
I checked the heater hoses to the heater core and one side is hot and the other hose is not. It is just a bit above room temperature.
I plan to get some hoses and try to back flush it to see if I can get anything out of it and if that helps but, I plan to keep this truck for a long time and do not want to be in a situation where I need heat and it goes out again. So I plan to replace the core and would like to know the proper sequance with any pics or diagrams that may help me.
Thanks for your support,
have the same problem?
