Thats better than $100. but Im not sure its worth it yet for me to change it. Maybe next fall. wethers too miserable still to be messing around in there without a garage.

Would this monovalve kit possibly improve the overall heat as well? As I was saying, when Im at an idle the heat decreases quite a bit and will only pump out heat again when the rpms go up. Or would this be more of a coolant flow issue? (perhaps bunged up heater core)
