I had an overheating problem this summer with my 302. I don't have much original on my car and I did not know the history of the motor. I did not have the fan shroud; but I also noticed that there was almost 2 inches between my 4 blade fan and the new radiator.

So,I installed an electric pusher fan in front of the radiator. To do this I had to use spacers and long bolts for the radiator. Now, I get extra air pushing from the front and the 4 blade fan is about 1 inch from the radiator. It seems to keep the temp under control. I have not added the shroud yet; but I still plan to get one.

Good luck on solving your issue.

If you do a search on this forum you will find many, many posts on this topic along with many, many suggestions, debates and arguments. Start with the simple things and work from there. It's tough when you don't know the history of the car.

I think it was Bartl that said to pull the radiator and take it to a shop. If your thermostat is working properly and you water pump is pumping water, that would be the next logical step.

I just gotta ask the question...how do you know it's overheating? What are the symptoms? You cannot always trust the stock gauges. If the radiator is overfilled, it will puke on the ground. What is your actual temperature?

Some people put on aftermarket fans and discard the shroud which helps cooling of the engine. Second if the car has sat for a while you might want to take out the radiator and have it pressure tested for flow. If any of the passages are clogged it would definitely make it overheat.

I guess you misunderstood my meaning. I said most people discard the shroud and put aftermarket fan on.the shroud helps cooling of engine but people discard it anyways be it getting broke taking it off or just too lazy to put it back on.

I agree as in my second reason for overheating.

The vast majority of 64-70 Mustangs had no shroud from the factory.

My 68 fastback had a shroud from the factory. I guess that makes mine a lil more rare to go with my rare bench seat.

I dont have a accurate temp gauge but i checked the temp with a infrared thermometer and it was up to 200 after a short drive. I also had the cap off to work out some air in the system, had some boil over so i had a bit too much fluid in there but it should be good now. Thanks for the help yall!

170, 200, 289, 302 cars didn't get them unless they had AC or the Extra Cooling option.

Actually I was just messing with you! But I do get your drift. I am one of those that took the fan and shroud off, then took the radiator out and replaced it all with aftermarket aluminum radiator and electric fan.

Depending on your altitude, water does not boil at 200...so you did not have boil over. What you had was expansion and water is pushed out. If you let the water level run about an inch low (and still above the tubes) this will provide the expansion room at the top of the radiator and you should be good to go.

Keep in mind the thermostat controls the minimum operating temperature, not the max. You should be able to run 210 to 220 without any issues.

I had a problem with it overheating on the highway. After checking timing, lower radiator hose for collapse, fan clutch and fuel delivery, I brought the brand new Mustangs Unlimited radiator to the radiator shop. They measured 8 fins per inch when it should have 12 - 16 fins per inch. He said it's a common thing now, and many of these overseas radiators have the wrong build specs.
