In this episode i will show you how to install a aftermarket coolant temp gauge the fast, easy and best way. I needed a temp Gauge on my 1950 gmc and the one on the 1988 suburban instrument cluster wasn't working. The cheap ebay crap digital thing i thought would be the cheapest one i could buy also not working. I was in advance auto parts one day and found one for 16 bucks and thought wow that seems cheap and it is a bosch, so it is quality. I will show how to install it on a 350 from a 1988 gmc engine.
