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.
{Not the same unless at cranking and first minute of operation. Injectors/Nozzles are maybe a better comparison to sparkplugs. Glow plugs are a starting aid. Yes both wear out.}- {Injectors will still work a long time after but performance starts droping off after 80-120K miles.}
My questions are as follows:
How can I tell if I have a burned out glow plug?
{Hard starting, rough idle and smoke on crank up.
Test light from battery + to spade end of GP. That will get you started for obvious opens. }
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?
{Buy OEM or better parts several supporting vendors have them. Read several other posts for more advice on which is best.}
How hard is it to change (I've done many spark plugs - is it that much different).
{Maybe relatively harder than sparkplugs depending on vehicle but doable. Most on here are good do it yourselfers (me) some are mechanics some just need info to argue with the service reps so it depends on you. }
Any accessability issues? How much does one torque in the glow plugs, just snug or really tight?
{yes, passanger side is ugly I have read. Read other threads for advice }
Any advice anyone can give to me, I'd be happy to receive.
{Read read read the diesel page and enjoy the truck.}
Regards,
