Update on this topic My 52 3100 with the 1955 235 engine. I notice it was getting hotter on the gauge showing 195 degree as the weather started getting warmer. Everything on the truck is new or rebuilt, US radiator, adapter plate for stock water pump relocation.
I was using a 216 fan blade, I decided to locate a stock fan for 52 235 truck also notice the belt had some play. I purchase a size smaller fan belt so I had some adjustment. I checked the thermostat 180 it was working ok. I did put a 3/16 hole on the thermostat
as discuss earlier on this post. Also I check the timing and adjusted a little which proved the performance. While I was had it I installed a Billet aluminum overflow reservoir, which limited the embarrassing coolant puking when I would show up at events.
Now with the weather at 113 degrees, the truck runs at 185 no problem, even in slow traffic. The main thing I believe was the correct fan blade which is less then 3/4 from the radiator. Also the other things I did help too. The only time I use the pusher fan is when I`m climbing a steep road. The starter kicks over very easy after running the truck for sometime and only been sitting just a short time. Hope this might help someone else that has a similar problem.
