I recently installed a new water pump. The truck then gave 3 codes. P01C6, P0480 and P0529. No check engine light. I have driven the truck about 50 miles and the coolant temp never went above 198. The oil temp was 215 which is a bit higher than normal.
Clear out the codes and retest since the check engine light is not on right now. However, you did just work on it so it wouldn’t be a bad idea to visually make sure you see the cooling fan comes on.
