If I unbolt it do I need to drain the radiator fluid first since it’s attached to the upper hose ?
is there coolant in the radiator overflow bottle?I’ve just replaced the relay fuse and the therm switch fan in the radiator
If it is stuck is it repairable or time to buy a new one?Pop the thermostat out and test it in a pot of water, watch and see if the thermostat opens or if its just locked.
I like to watch the thermostat as the pot of water warms, rather than wait and see if it changed. You will be able to see the spring move
Having a hard time touching them together since they are in plastic coversis there coolant in the radiator overflow bottle?
did you test the fans even work?
pull off the two connectors from that new therm switch, and with the ignition ON, simply join the two wires you just pulled off.....do the fans both work?
