Small overheating problem

Hey guys, so now that we are getting some warmer weather in Oregon..this is my new 302's first time in warmer weather and it's testing my cooling system. Right now I'm running the stock 192* thermostat and a black magic electric fan and the car typically runs between 205*-210* which from what I understand is completely normal. But now with the warm weather It tends to creep up to 215*-220* under load at highway speeds and 225*+ in the city under a little load. I usually have to keep as much load off the engine as possible during warm days to keep the temp around 210*. Does this sound like a radiator problem and/or is a 180* stat gonna be benifical? I want to try and keep it running as close as possible to 195*.

Why not take the T-Stat out for the summer ? .... Or... Buy a 165* Racing T-Stat. My car runs with the needle about 3/4 or better on the Gauge all Summer long with no problem. It has a New Hi-Flow Water Pump, All New Hoses & T-Stat & a 3 Core aluminum radiator & Temp Sensor & it runs the same as with the stock stuff....No Cooler. Guess it's a Ford or Mustang thing.

Well since I figured it's gets a little cold in winter here I figured that might make it run a little cold for me. It's only warm 3-4 months out of the year here anyways. I already have a 180* stat on the way I was just having second thoughts.

Because the car needs to get up to a certain operating temperature to function properly. Leaving the tstat out or running a 160 is not going to allow this to happen. Do not run less than a 180 degree stat.

And to the OP, I'm guessing you are verifying your temps with a good aftermarket gauge? The stock gauge is worthless. I'd try a 180 tstat first and if your radiator is an original you might need a new one too. Mishimoto makes a good affordable one that many ppl run with great success. Also, there are some water pumps that are opposite rotation for what you need, make sure you are running the right pump.

Yeah I'm using a mechanical temp gauge..but it's the stock radiator..I was kinda figuring it's the radiator just didn't know if I could use a 180 stat as a "bandaid" in the meantime before I get a new aluminum radiator. But the fan is set to kick on at about 205*

Personally if your car is having overheating issues than I would make sure you don't have a fluid leak first and then I would probably look into installing a dual radiator.

I know I know just busting some *****.

I am using an old school Ford motorsport HD 2 core rad that I had laying around for some time. Took it to get clean out and tested. So far with that rad, SN fan and a DC contrller.....cool all day long.

Yup a good OEM Ford 2 core, electric fan and set to come on at 180 with a 180 tstat and she'll run cool all day. My 95 had a mechanical Autometer water temp gauge in it and it was pretty neat to be sitting in traffic at 95 degrees out with the AC on sitting rock solid right at 185-190.
