NGK glowplugs?..:

i’m buying a truck this morning. 1996 7.3 CCLB auto. 193k miles.

it’s a beautiful & clean truck, the owner took great pride and detail with this pickup. My ONLY concern is he said he used NGK glow plugs?… i have heard it preached to never use anything but motorcraft and that is my personal presence as well. question is should i pull them immediately within a few days of owning the truck?

it’s getting cold here in north idaho, -35°F wind chills the next 2 days. don’t think i’ll be doing it for a bit though. thanks guys. i’ll attach some pics of the new truck! 😃



flatbed being made

flatbed complete. he did an amazing job on it

My skid loader that has a Kabota diesel engine in it runs NKG glow plugs. The original plugs lasted 15 years before I replaced them with the same brand. The second set are starting to fail after 5 years. I don't know what the difference was, Counterfeit parts from China would be my guess. I have never heard of anyone using NKG plugs in these trucks, so really don't have an answer for you, other than the old plugs in my loader came right out when I changed them.
By the way that is a nice, clean truck.

No experience with ngk plugs, but for safe measure I would change them out for OEM FoMoCo plugs from a reputable source.

this is what i’d prefer to do. he said he replaced the GPR and glow plugs but it still doesn’t start very well in the cold

Not starting well cold could be a tired starter, wrong CCA batts, or janky cables...or just flat out cold there.

Try to plug it in if you can, this will go a long way making it easy to spin up.

Yes, clean ride!

Starter needs to crank over at 200 for 30 seconds.

If it starts easy with block heater then injectors could be worn. Armeture clearance too low causing delay in timing makes for hard cold starts.

My 91 tractor uses NGK glow plugs.

my bet is glow plugs, and possibly a weak starter. not injectors. most people do not realize the starter is tired until it no longer starts.
the plug in for two-three hours before trying a cold start will be the test. if it cracks rite off, glow plugs. if it still hard starts, starter.

while this is an IDI, the difference in starter speed is easily detected.

I swapped batteries out of my 97. they’re brand new from napa. it turned the starter a lot faster. but still was smokey. anyways. it’s bone chillingly cold again today. single digits during the day. google currently says -8°F (feels like -29°F) 😱 so i don’t think i’ll be doing much of anything 😂

I pulled the glow plugs out today and used Ford Motorcraft from Clay at riffraff. I almost ordered them off of Amazon until I read that there’s a bunch of fake OEM products on there. . Buy from
a reputable source.

Started the truck up and it smoked significantly less and shook significantly less on startup. The other glow plugs were installed in November, but they look pretty bad already… I know that they tested OK with the ohm meter but they just visually look rough. It probably did not help that the driver side harness plugs seemed to have barely been connected, when I pulled them I hardly had to use any force to disconnect them…Which is weird to me because I tested the resistance on every plug through the valve cover harness before taking it apart and they all came out ok. I’m just thinking that the loose connections might not have been allowing it to heat up.NGK are garbage anyway.

My money says fake NGKs. They are OE supplier for plugs and O2s. People are cheap and always go for lowest cost over quality.

Hell, Beru makes Motorcraft GPs.

Regardless, glad yours starts better. Mine is parked.

back in the 80's we used to call NGK "no good krap".
they were ok for vehicles that were designed to use them. japanese cars and two stroke motorcycles.
but for american made vehicles?? nope. use what the manufacturer used when new.
ford get motorcraft, gm gets ac/delco, and chrysler gets mopar

No 2 is hovering between $4.50-5.00 in my area while 87RUG is about $2.40-2.70. I am not hauling or pulling anything currently, so financially pointless to drive also plus the higher insurance cost over my Lobo 5.4 or even my lowly 4.9. I am keeping it as everything is fixed on it except a tired long block, which I have already started running numbers on to rebuild.

Besides, I can still help some guys and others me when it comes time to reassemble that 1997 four door dually I have at Donald's ranch...not to mention laughing at me the entire way!
