you have to burp the air out and add more coolant to the rad to get it full the first time its filled after the pump has been off

then with it full and some water in the recov tank

let it idle,with the cap on and tight, till the temp comes up...

see if it goes much higher than the 190* of the stat

it may steading climb with no fans,so let it get about 210* and shut it down

as long as its not boiling over,its working correctly

pushing water out of rad into the recov tank when hot

sucking it back into the rad as it cools back down

cap has to stay on and closed..also has to be vented..so check that you have the right cap also

you will know if its boiling over when its filled the recov tank and is pushing water out of it

210* in Fl summer heat is the norm on most of mine but drops down to the 190* with air flow

How hot is it? It may have air it like he said.
