Thx NOSbeast for the idea . I really thick the gauge is at fault reporting 25-30 degree high . I took the truck out on the road drove at 235degree (per the gauge ) for 2miles nothing happenewd ie. no smell of overheating , no steam , no overflow into holding tank. So I really think it is OK.
Next thing is to sell it. I will post in the swap area and see what I can get, Thinking I paid $2,000. and put in $500.00 so we will see.
