Should I do this?

[Zinger]

After posting my last post about having typical cold starting problems, I decided I would check my glow plug relay and not take the word of the "mechanic" that said it was good. Well, based on Marc's great explanation for checking the GPR, it is not good. I want to preface the rest of this with my previous statement, I am not a mechanic, nor do I pretend to be one or play one on TV. My question is, Should I change the GPR myself or take it in to be done? Before you answer here are two of my concerns. (1) the hot side of the relay looks corroded and possibly burned, and (2) as simple as it looks to change it would be my luck you have to disconnect the transmission or something in order to change it. If it requires anything more complicated than disconnecting and reconnecting the wires, I would rather let someone competent do it. Thanks for your help. I love driving this thing but working on them is another language.

I am not a tech nor have I done this repair, so I'll just give a till a tech sees it. Good luck with it!!

I'm not sure what year truck you have but on my 97 there were 4 wires on the top of the relay and 2 bolts holding it on all you have to do is remember what wires go where quick and easy

my 96 was easy just like above my 02 looked easy but the wife took it to work so i cant look real quick

What year is your truck? It should be relatively easy like said. If you want just draw yourself a diagram of the GPR with pencil and paper. Reconnecting everything then would be easy just refer to your drawing.

i am no mechanic but i replaced one not long ago on another truck, it took about 5 to 10 minutes...there is a post on this in the tech sections.

I have an 02 F250. It does look simple but my luck has always been, when it looks simple you are really going to screw something up big time. Guess that is one reason I never got more interested in mechanical stuff than I did. As a teenager I had a couple of old VW's and I spent more money on repairs to things I demolished doing my own repairs than I would have spent letting a "real mechanic" do the work to begin with.

OK, I did it and the beast cranked and there was no fire. WooooHoooo!!! It has warmed considerably so the real test will be to leave it unplugged and see what happens in the morning. After installing the new one I tested it and at least know it is working properly.When I got the old GPR off it appears the hot post did just that. It is cracked under the connector where it could not be seen until removed and some of the plastic hood that covers the post had melted. Hopefully that solved the problem. Thanks to all of you.

So glad you got the courage to do this yourself. There's a sense of satisfaction fixing things with your own 2 hands.

sounds just like the one i replaced on my 96
