Re: idle surge coolant fan runs all the time
Needs tuning?
For the fan on all of the time look to see if a PO wired the relay to be active all of the time. Some put a switch in the interior to control the fan relay.
ECM may be in limp mode, that will cause the fan to always run. Check the SES/CEL blink at key-on, engine-off.
