How to change glow plugs - Diesel Forum

First time owner of a diesel. Just bought a 91 f250 aprx 60K on the rebuilt motor. Im having problems with cold starts. previous owner thinks it needs new glow plugs. I was going to use Wellman single coil plugs. My question is, does the turbo need to be removed to get the plugs out?

No, but you need nimble fingers and a 1/4 inch drive set. Best GP's are the Beru ZD-9's.

have you tested the glow plugs with a test light? these glow plugs will fit your year even with the add on turbo 7.3 Liter Diesel Motorcraft Glow Plugs - Ford 7.3 Liter Diesel Motorcraft Glow Plug replace all 8 and use anti-sieze on the treads of the new plugs before you install them. if you need a glow plug controller this one is at a good price

these constant duty plugs are the best that you can get. they also come with a big price but I believe they have a lifetime warranty.

Beru does not recommend antisieze with their GP's. Beru's come with a nickel coating.

just dont break a tip off in the engine though it can kill the entire motor
