Hey everyone, first of all I would like to thank everyone on the forums for their efforts in sharing their experiences and helping each other out. I have been a lurker here for the last few days while my membership was approved learning as much as possible about the car I was about to purchase. In short, Hi, I'm new.
I recently purchased a 94 with 16K miles that has never seen a bad day. The car has had the head gaskets replaced (by whom and with what I don't know) and otherwise had all of its maintenance. I plan on going through an flushing all of the fluids including gearbox, diff, coolant, brake, power steering and blinker fluid over the next few weekends. I am a car collector of sorts and enjoy driving everything as much as possible- the Viper being no exception.
That said, I spent hours digging through posts about overheating and thermostat recommendations, fan kick on temps and the works- however my issue appears to be the opposite. When around town and traffic the temperature sits pretty and stays near the yellow however on the highway at 75-80 the temp slowly drops down to near nothing until I resume normal in city driving again. When the car sits overnight and I go in the morning to war it up, it does so quickly and when left to run at idle for about 15 minutes even cycles the radiator fans.
My concern is possible damage to the engine from overcooling or major temperature swings with varied driving. Of the possible scenarios I thought it could be a stuck-open, bad or otherwise missing thermostat, bad temp sender or disgruntled gauge. I plan to temp gun the radiator when this is going on to see if there is actually a temperature difference or if the car is just poking fun at me. Has anyone had this sort of issue in the past? Thoughts? I included a photo of the gauges while cruising at 75-80 after about 15 miles.
Thanks all! (ps, sorry if I am posting this in the wrong area or improperly posting images, let me know!)
