I have a 67 cougar with a 289 that's been running hot after i come off the highway, and only after coming off the highway, runs very cool in town all day and while on the hasn't had a major overheat just a little in the overflow bottle. I have changed the water pump, thermostat, radiator, it has a fan cowling, dosent smoke, and has good compression, the brakes are not draging and the car runs good in every other way. any ideas where i go from here?
