Short trip in my 69 c10.
My cousin is moving back home with her parents. It was a while since I had my truck on the freeway. I stoped using freeway because I need to redo a front end. Front suspension has a lot of play. So this morning I drove to South Pasadena and load the truck. I am running a 4 row radiator with a late model firebird dual fan set up. Around town it runs at 170 degrees. It was overheating a little at 200 degrees due to 3500 cruising rpm. Truck actually handled and stop better when it was loaded. I need to do some sound insulation inside the cab. Anything from 3500-4000 rpm and it's hard to keep a conversation going. Nothing broke during the trip but th400 sprayed oil all over the place. I will need to see why. I already got a biggest summit alum radiator and trans cooler on oder.

Re: Short trip in my 69 c10.
200 degrees isn't hot really. The stock thermostat doesn't even open until 195 and those gauges aren't always perfectly accurate.
3500-4000 cruise RPM is way too high if you're going to do a lot of cruising. How far away does your cuz live? Rents up there are pretty crazy,bet she saves a bundle living at home.

Re: Short trip in my 69 c10.
If you use distilled water instead of regular water it will lower the temp 10 to 15 degrees

Re: Short trip in my 69 c10.
The high RPM's have anything to do with the high temp?

Re: Short trip in my 69 c10.
Have any picture of the fan setup? Might be blocking airflow through the radiator at speed. My cruise rpm is high as well, 3100-3300 rpm. Runs 190 degrees with a nylon flex fan and 3 row radiator on my 350.
