Im lost right now as to what this issue could be guys the radiator it full and the car is not acting like its overheating but an over heating issue false or not always needs to be resolved so if any of you have an idea what this could be that would help tremendisly. I now have a 25th annversary canvertable with the v8 305 which the guy i bought it from have it rebuilt so any helpw ould be great thanks guys

It sounds like an air pocket, take the cap off and let it bubble over out of the radiator at the same time make sure the coolant starts to circulate when it gets up to temp and the T-stat opens.. Also try to park a little up hill.

Sounds like a bad fan switch. (I assume electric fans.)

thanks bro for the help im just confused as **** right now ill do that and see if it works

Need more info...Electric or manual fan(s)? Fan shroud? Does it get hot at idle or when driving?

Also it may be a dumb suggestion, but make sure you are using 50/50 antifreeze and water. A radiator tech once told me changing the ratio to more than 50% antifreeze would make the car run hotter as water is a better heat sync than antifreeze. The more antifreeze beyond 50/50 the hotter it may run.

Once you confirm the coolant is circulating, warm it up and check the temperature with a thermometer. This will let you know if the guage or sending unit has failed.

if it isn't boiling the water, it isn't "overheating".
those cars are supposed to run at about 220 degrees- and with a good radiator cap, they are "safe" up to about 250.
i think the gauges on those cars are run by the ecm- so if it says it's running at 230 all the time, then you might have a bad temp sender in the intake.
that being said, do you have all the ductwork under the front of the car? if an air dam is missing, it will get hot on the highway.
