The spring time started out fine except my temp gauge was sitting quite high while driving normally. I figured that maybe my thermostat was pooched so I replaced it. Well, that changed nothing. Then I changed my sending unit. Again no change. I found that my oil pressure gauge was acting funny so I decided to change direction. Thinking the problem may be in the instrument voltage regulator, I have decided to change that out. That was not fun at all. The reason I though it was the volt. reg. was because the needle on my gauge was burying its self. But I would stop and get no boil over at all. Just last Sunday (July 8th) we took the car to a show 2 and 1/2 hours away. The needle was buried most of the drive and when we parked there was no boil over. HELP please. Thanks ,Dave.
