Hello, I’ve got an 82 scottsdale with the 305 that’s currently experiencing an intermittent overheating issue. It commonly happens when at idle or at low speeds but sometimes it’s just random like for example, i was making a 45 min trip which was mostly downhill sloped freeway and holding about...
1984 -C10 with a 4.1(250c.i.d.) inline 6. Was doing fine, then one day it would not show warm on the gauge. Replaced thermostat, seemed to work for a little while then back to showing cool. Gauge will not move off of "C".
We redid the interior on the truck and my son broke the gauge needle...
