Replacing Block Heater

[spindlewood]

An excellent point about testing the cord. Before I replaced the heater, I unplugged the cord and did a multimeter test on the two heater prongs. It didn't register - it was dead. I tested on the new heater and the multimeter showed the resistance correctly.

we (meaning me) generally learn a lot from our mistakes....

I once replaced a perfectly good block heater by jumping to conclusions. Once. I have replaced several cords and plugs since. In fact, right now both my wife's and my pickup have replacement plugs.

Sorry for the way the pics. loaded I should have done it individually. I first installed the sleeve because I could I could see no way to safely install it without possibly harming the heater & used that long brass punch to do so. One thing I would do next time is mark the heater so the pins are horizontal to the motor. There is no top and bottom the wire plugs in either way but with them being horizontal the plug on the wire could be installed with the wire straight down. Not critical but neater and less kinks. With dope on the threads there's no need to over tighten but let it set over night before firing up this will allow the sealer to set and insure no leaks. I realize I'm not great at explaining so just ask and I'll do my best with any questions.

Could you post part numbers and sources, please?
