Heater core bypass or maybe block?

[martin31636]

Morning cheby dudes,

I have the lame blender door actuator  bullcrap going on. I have been looking at the parts and checking the videos on replacing them. I am no newbie when it comes to mechanical maintenance. But. I am old and lazy. And not a small fellow. So working in and under that dash is an absolute nightmare. My fat paws are not going to fit and I see myself tossing tools across the yard. So I am starting to lean towards just bypassing the core. I have driven many shitboxes in my time and I think every heater core in every damn vehicle I have ever owned has failed. I am still new to the 2014 Silverado. My question is:

Does the core flow have to complete/circulate? In other words could I just put a 2 way valve in the inlet side and block it during the summer? I am still trying to find schematics online on the piping. It looks like the core may be an alternate route like it doesn't have to complete for the coolant to flow. I'm sure I'm wrong and it's a normal setup. So I am now trying to plan a 3 way valve setup so I can bypass during the summer. And open it during the winter. The only time I use my heat is the 3 or 4 times we actually have a heavy frost and I need to get ice off my damn windshield. I'm in south Georgia so not having heat has never been an issue but it is nice to have on those rare occasions. 

 

Just curious if anyone has gone this route instead of dealing with those darn servos under the dash. That I'm sure will just fail again. 

 

Thanks

Martin
