Just rebuilt my 305 for the second time........... Engine is running great only has 300 miles on it so I am still breaking it in. I am running a 180 thermostat......... Have the fan running all the time but for some reason the engine seems to wanna creep over 220 in traffic after she has been on the highway for 10 minutes. Just put in a new cooling fan motor. Has anyone had this problem. Is there a stronger turning fan motor out there? Also I have check my cooling fan circuit from the wire and if I ground the wire at the switch she comes on. I have gone through two different cooling fan switch's and neither have turned on the fan. I even went as far as cleaning the head where the switch is crewed in with a wire brush. But no difference.......
Any suggestions

Il bet your air damn for the radiator is banged up or even gone that will cause this problem. Is it getting hot at speed or stopped?

 

the air damn is in good shape. The car does not over heat when on the high way. It seem that when Im in stop and go traffic is when it starts running hot. Any other hints??????

 

Hmmmm, i don't know you could run a direct toggle switch for the fan. I have also heard of people having a bad Rad cap which can cause problems, probably not a factor here.

 

Well I have not pressure tested the system yet........
and the engine is breaking in.......... but I think something is a miss in my little car...... I still can't figure out while the cooling fan will not kick on with the stock switch. cause I want to hook up the ac...........................


Hmmmmm
