Hey,
I recently located from living with my parents in metro Detroit to western Michigan. I'm going to WMU, which is located in the snow belt. I want to install a freeze-plug engine block heater, but I don't know how I can, if possible, do so on this car. INSTRUCTIONS PLEASE!
How much of a job is it?
Thanks,
Dan

 

to my knowledge they are hammered into the block, not threaded. cost me $400 to get mine replaced at a mechanic at $65/hour.

also available are electric heat pads that get epoxied to your oil pan or block or wherever you want. they sell for 60-80 bucks here. i had considered trying it untill i took my skid plate off and seen the grooved oil pan, took it back and got the freeze plug type. besides, im sure the freeze plug type works much better.....

i have no idea whats in your freeze plugs now, but whatever is plugging it, you need to get it out and hammer in the block heater lol

 

Block heaters typically are o-ring sealed instead of an interference fit like the original core plugs are. All of them that I have installed have a bolt in the middle of them that tightens down on a strap that goes inside the block. I just had to replace the one in my K5 because the old one was leaking. Pretty easy job provided you have access... On an s-series, it really isn't all that easy.
