Hello...

I have always owned gas powered trucks until now, with the purchase of a used 1995 K2500 6.5L

The truck runs fine, but I always changed the spark plugs on a gas block. I figure that I should do a similar task with the diesel and put in new glow plugs.

My questions are as follows:

How can I tell if I have a burned out glow plug?

What else should I be looking for when looking at the used plug?

Is there any brands of glow plugs that are best or should be avoided?

How hard is it to change (I've done many spark plugs - is it that much different).

Any accessability issues? How much does one torque in the glow plugs, just snug or really tight?

Any advice anyone can give to me, I'd be happy to receive.

Regards,

...Byron
