Odd heating issue
Hey guys, it's me again. I spend a lot of time asking questions here on this subforum, haha. I've finally got my timing/carb issues taken care of and am moving on to other issues.
The problem I'm having is that temp sensor isn't going above 140* on the backside of the engine. The temp sensor for the e-fan (which I have in one of the front holes) goes to 180* easily and kicks on my fan. I have Vortec heads and have the bypass hooked up but I was thinking maybe I don't have it hooked up correctly. Here is a picture: A) E-Fan Temp Sensor. Reads 180* with laser temp gun B) Gauge Temp Sensor. Reads 140* with laser temp gun and on gauge C) Front Vortec bypass hooked up from my water pump. I installed this per intake manifold instructions I have checked my thermostat on the stove and it works correctly. I also have the bypass hole blocked on the front block (small lower hole on passenger side water pump galley). As always thanks for your help!

Re: Odd heating issue
I am gen I, but put my temp sensor in the A spot. The Painless controls are on 185/off165. I run a 160 stat, & she holds her line, with 2- 14" fans.....never over 175-180 on the hyway, never over 190 in town traffic.? Longhorn

Re: Odd heating issue
It seems I learn something new every time I go on this site. I have always put the the gauge temperature sensor in the driver's side head and a fan sensor in the passenger side head. My newest truck is a '92 and that is where they were put in when it was built new.

Re: Odd heating issue
I always put the temp in the thermostat housing on the cold side, so if the temp doesn't rise, you know the thermostat is stuck closed.........
