#1 hot start stumble- not every time then goes right away
#2 temp guage creeps to 3/4 occationally usually after long drive.
Radiator looks ok but I think it does weep on the side, coolant is clean and green, new fan clutch, cleaned tb and stepper. Neg for exaust gas in coolant test. replaced hose clamps. Bleed the coolant system. fixed leaks no real leakes. I dont think the impeller fell off my water pump I can see slight bubbling through the plug hole when running. Any suggestions I know the fuel temp sender but its 100 dollar part. Thanks
