What has changed in your combo from this point in time??? It was exchanging heat and dropping the coolant temps.
"At idle in my carport it comes to 170* the t stat opens and it drops to 150*ish. when it warms that water up the stat opens again and hot water from the rad coms in and a few seconds later at about 210* the fan comes on and brings everything back down to 170-180* idling fan goes off and then on and so on. it works in the carport.
This still happens. except now it has a mechanical fan. no electric fan, so it starts heats up, opens the t stat- comes down then slowly rises to 210ish.
I took it for a test drive, it hung out around 200*-210* driving. seemed fine there, when i came to a stop it would slowly come down to 190-180* start driving again and it would go back to 200-210*. Maybe it isn't the best radiator? maybe the small ports on the housing don't flow enough water? maybe its a combination of it all."
now it heats up, and seems to stay around 210*, like its getting heat soaked. i don't know
