Re: Overheating?

Make absolutely sure that it is the exact sender for your application and the gauge you are running. I just went thought that on my 77 The temp always read low so I ordered a new correct for the application Delco sending unit and it showed hot. I did swap the 195 thermostat that came with the truck for a 180 and now it runs with the needle pointing straight up on the gauge. I'm swapping radiator and all hoses in a couple of days when the 4 core gets back from the radiator shop and will get the heat gun out then.

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
