Being very electrical minded but not very mechanically sound...I want to replace my glow plugs, but without loosening things that I should not require the location of the glow plugs. Are the three on the front part of Isuzu 3ld1. Or on the top of engine ??
See pics
1st. pic is your 3 injector pumps
2nd pic is the injectors AND the glow plugs behind the injectors. They have the buss bar connecting all 3glow plugs. Seems like you will need a 10mm deep socket to get them out of the head. You can't see it verry well in the pic but the wire that feeds the buss bar is on the glow plug to the left most looking at the pic.

They are really easy to change and they can be tested with and ohm meter or you can hook them
up to a battery and they will turn red if good.
By the way.. after I located them, they were VERY easy to change!
Thank you!!
