Re: A 1962 GMC 1000 Series Utility with Extra Goodies
I am still just fleshing out the condition of the engine. I did a flush of the coolant and used a product called Blue Devil radiator Flush. I don’t think I needed it, because everything that came out after 4 flush cycles seemed pretty clean. I did put a new water pump in as well, so maybe that was the issue that was the culprit.
* Correction, I did need it because I got dirty blackish sooty water coming out
The engine will start with the CDI Button pushed IN, or button OUT for Conventional meaning points.
I temporarily added a mechanical water temperature gauge and oil pressure gauge. It was about 90 degrees out and I let the truck idle for about 30 minutes and these were the numbers I received. Those were with just water in the radiator.

I also changed out the canister oil filter to the Spin On factory unit.

Overall I am pretty happy with the numbers I received. Oil Pressure started out at 50lbs with the choke on and dropped to just under 40lbs with choke off after two minutes; then to just under 30lbs after 30 minutes of idle and water temperature showing a steady 175 degrees thereabouts.
They truck is "drivable"; That is, I moved it a few feet using 1st gear and 2nd (SM420), E- Brake works and pedal holds, but not ready to road test yet. I need to work on the brakes shoes, cylinders and hoses and then some tires.
Also I have been polishing up that aluminum topper little by little and it is shining up pretty well after so many years. I used Mags Aluminum Polish
