I’ve been taking out the truck for some drives lately instead of wrenching, since the weather is turning good.
The old temp sensor was bad, so I picked up a duralast sensor that was supposed to be correct. Well, it’s likely off. I have a 160 thermostat, and it sits stable at just under 210 and doesn’t waver, so I’m guessing the ohms are off for what it needs to read right.
What do you guys check with, or do you have a recommendation as to check accuracy?
It was a 250 I6 truck originally with A/C but has a 355 in it now with some sort of a lumpy cam, and camelhump heads. I didn’t build it, but it is freshly rebuilt with a new water pump and when at 60 mph it’ll creep up to 220 on the gauge when it’s 70 degrees outside- which I suspect is lower than that. I need to measure the actual core size of the radiator, will post that later. The guy before me that owned it, well, I don’t consider him an accurate source of information but not dishonest.
Timing is set to 35 deg of advance at 3500.
It seems happier when cruising around town- heat rises when consistently at highway speeds, and then cools down when back in town, making me think that the radiator won’t keep up when real summer temperatures hit.
Open to any and all suggestions, except for electric fans. I’m stupid, so I’m keeping it simple as they say.
