2006 Gulfstream 30' Class A, Ford V-10, 6000 miles.....
Problem: MH running fine then all of a sudden immediate overheat indication, then immediate drop back down to normal....
Going up the 405 thru LA and overheat gauge goes rapidly to max for a few seconds, then drops back to normal....Does this every few miles...I knew it was not overheating, engine was normal temp and coolant was full....Heading to a repair facility when gauge goes to max and stays there....After about a minute, engine goes in "fail safe" mode, operating on 5 of 10 cyls......Really fun in LA traffic...Pull off and engine feels normal, coolant fine, so I know it is some type of false overheat.....Engine off and on re-start operates fine....Get to a GREAT Ford dealer in Arroyo Grande, Ca (Mullahey Ford) who diagnose the problem as "false overheat", covered by Ford TSB.....They fix the problem and all is now fine after another 1000 miles.....
This Ford dealer knew we were just "passing through" but treated us great.....
