The heater lines don't matter. You probably need a new thermostat and replace the rad cap while you are at it.

Im lucky if mine gets up to N on the gauge this time of year. But as long as ive got heat in the cab it never really worries me that much.

My last motor wouldnt ever put out any heat, but here in Florida it doesnt get very cold so I didnt worry about. It never overheated so I figured it was fine. I did pull the tstat when the motor died but I have yet to test it tos see if that was the problem.

Was it a Mortorcraft thermostat? Is the fan clutch locked up?

You need to flush out your heater core more than likely, it should put out heat even if the motor is only 100 degrees. I don't know anybody that removes their fan for the winter, David 85 did run his for a while to test the mileage. If you have a mechanical guage install a mexican thermastat and see if it warms up. Is your fan clutch locked up and how far at a time are you driving it.

A few years ago a friend of mine was up north and the temps got way below 0, when he got back to town he had his matress tied to the grill on his kw. I about rolled on the ground and still give him a hard time about it.
