Truck running hot
My`72 K2500 has a problem when it`s hot out.The tempurature runs up when it`s good and hot outside,only.I can run it easy and it will climb slow on the interstate.On back roads I drift it in neutral on hills to get along.
It had a flex fan/solid spacer and I switched to another fan w/clutch yesterday.It ran ever hotter.I just went out and got a new clutch and put it on.But,the other one seemed fine.I had a t-stat housing seap and I fixed that,too.The thermostat is working fine.I wonder if the TH350 could be running hot for some reason causing this.I haven`t checked timing,but it runs fine on regular with no pinging.It did it last summer,too. Any suggestions?It doesn`t use water and runs cool except when temp get near 90.
