Hey allHey Guys
Replaced my glow plugs
did anybody have oil on the end of the glow plugs?
not sure how bad that is?
where wold the oil come from?
I measured the old ones at around 0.7 ohms. The new ones were at 1.4 ohms, so it will probably take twice as long. I'm in the Sacramento valley (California), so I probably won't need them very often anyway.Should be interesting to see how it affects starting? I am not sure if there are different resistances or temperatures in glow plugs?
I’m gonna try and get to it and clean tonight.Glow plug is intermittently faulting or poor connection. Could also be the glow plug relay, I believe that’s located near the ecm Towards bottom of chassis. Mine went a month beetween codes and ended up being glow plug
Do you have some close up pics of exactly where the glo plugs are ? I see the plastic T handles.Replaced the glow plug yesterday and it went smoothly. I drove the truck about a half hour each way to/from the dealer to get the part so the engine was hot when I removed it. Here’s a quick step by step of what I did:
- Disconnect MAF senor, remove air box & air intake tube up to the 90 degree boot to the turbo
-removed the EGR Diffuser Tube to get a little more room to work (not really necessary but I would recommend)
-pull up on the small ‘t’ shaped plastic handle of the electrical connection to the glow plug. Might have to wiggle/twist as you pull but it should pop right off.
-spray some PB blaster, use a 6pt 1/4” drive socket and small 1/4” ratchet with a short extension (so you don’t use too much torque). Mine broke loose easily but started to get harder to turn after a couple if turns out. I just kept spraying PB and would go in and out a lil further each time. Probably took 20 mins of screwing in and out / waiting each time I sprayed PB for it to soak in.
New one went in just fine. Problem fixed!
Are you just referring to the location? That I can see as it was hard to get to the plugs. Cleaned and greased yet the error comes on intermittently with no rhyme of reason.I’d dielectric grease your connections and start with the glow plug relay before attempting removal of the plugs, I fought with mine till I replaced the plug and it fixed the issue. It’s a pita to replace the plug. I’d advise beer and plenty of lube and time to ease it out, or take it to a diesel shop and let them do their magic.
