Hey guys I think I maybe be needing to replace water impeller. The temp has been running around 200deg in stead of 175deg like it usually does. I would like to get it done before the Vet run but with schedule and shops being busy thinking of doing it myself. I am not a mechanic but I am somewhat handy. What are your thoughts as far as doing it yourself. Accessibility, time, how easy/hard ect. Thanks and any advice will help.
