Their may be air in the system, also check your motor oil level.

Oil level is good. I also bled the system before attempting to drive around the block. It idle for about 45 minutes, no issue. Half way around the block and begin overheating.


cooling fan operating normally? at idle it dosent over heat but when u drive it the fan clutch may not allow the fan to keep up with any wind resistance it may be getting from the outside. also check the hoses for blockages.. sounds elementary but replacing all those new parts coudlve jarred some gunk loose
