Ok, this rough starting when the car is cold is getting old. I need someone to come help me check and change the glow plugs on my 93 golf. heated garage, can supply choice of beer, or even fix your computer. Located in South Surrey, or can come to your place. Any takers?
I'm not an idiot, i'm mechanically inclined, just don't have the know how and don't wanna *** something up.

And just how close to Salt Lake City, UT is that?
Dig out your Bently and go step by step.
1) DISCONECT THE BATTERY GROUND CABLE!!!!!!!!!!!!!!!!!!!!!!!
(yep, very immportant!)
2) Remove the hard lines to injectors (17 mm wench should help [of the
tube type])
3) Starting with #4 (passenger side) remove the nut on the end of the
glow plug (an 8mm wench here) (Yes we did the hardest first).
4) With all the nuts removed, gently ripp that damn buss pos out of the
way! Or just tickle it until it falls out.
5) Remove glow plugs (Hmmmm lost another wench, cheeky darn
thing! :oops:
6) Check to see if you have fast plugs or slow plugs. Slow plugs are 9
Amp, fast are 15 Amps. DO NOT USE FAST IN SLOW, OR SLOW
IN FAST SETUP!!!!!!!!!!!! One will burn up your glow plugs FAST, and
the othe will never get the job done.
7) TEST your NEW glow plugs. Jumper wire from terminal to + battery,
theads to neg side, 10 seconds should be "GLOWING". Just because
they are new, does not mean they work.
8) Install NEW TESTED glow plugs, starting once again with #4. (If you do
the hard ones first, you are less likely to be fusterated and mess up.)
9) Replace the glow plug buss strip. (Or REPLACE the glow plug buss strip
with some #8 wire with the proper terminals on it. 4 plugs, 4 wires
all going to the fuse there. Or thru a relay setup like..[Ooops, thats
a different post!])
10) Reinstall hard lines to injetors (Where did that cheeky bit go?)
11) Reconect battery ground. (Okay, what did we forget this time?
Hummm....... Got that, that and .... that. Just checking!)
12)..................Oh Yea, start car! (You DID pick up ALL your tools and
wenches, no?) :twisted:
That's how to replace glow plugs, Wheather that was your problem or not......? :roll:
FOUND IT!!! That paricular wench looks alot like 12mm! :lol:
A case of San Migael Dark souds good to me.

That's BC right?
I need my computer fixed too :(
-
yeah, it's in bc. thx for the step by step, maybe i'll give it a go. I'd like to kill that bus bar too, where's the how to on that, that will make it easier to test which one has failed in the future right?

Okay. opperater errer, so we will blame the computer!
Yes, it does make it easier to chase down a single dead glow plug.
The relay setup is a couple of diffent ideas put together...... Larger sized battery wire (#2 Weld cable, a "HOT" post remotely located from either the battery or the starter + post, relays and fuses to run the glow plugs from the "remote" + post, (using the GP relay to trigger the others), all to insure max voltage/current at the starter for cold starts. Also larger wire from the B+ post(s) on the Alt. Larger wire to ground Alt, #2 weld cable from starter mount to new (larger) ground bolt on trany mount bracket, #2 weld cable from there to batt neg,.... you get the general idea ...........

Bring it over, I'll give you a hand, I'm in Burnaby by BCIT. I've got all the tools, and VM Autohaus is just around the corner to get parts from. PM me for contact info and to arrange a time.

finally had to do it today. went to drive home from work and the car woudl barely run, sputtering, running on 3 cylenders.
got 4x bosche glow plugs at lordco $14.30 each, what a deal. took me around 2 hours, needed magnet on a stick, blue tacky stuff, 8mm and 12mm ratchet wrenches, giant screwdriver and a lot of patience!!! stupid design.
-
i didnt know there was 2 different types, 2 of mine went on my aaz so i took 2 out of a realy old n/a 1.6 tested them and then put em in, is that bad?
how long will they last?
omfg im so stupid :roll:
duno bout you guys but i just take the pump off to do my plugs, done it so many times now i can do it in my sleep
-
so i suppose dialing in that pump is super easy eh....seems like alot of work to just get at teh GP....my pumps already off so i suppose thats part of the problem out of the way... i could see number's 1 and 2 being a real ***....
As for the difference in Glow Plugs heating time....how would someone check to see they have the correct ones or whats the difference in apperences? thanks ive never heard this before...
-
I just did mine on Monday when the temps finally popped above freezing.
For #3 & 4
deep 12mm socket
8mm socket
For #1 & 2
12mm ratcheting box-wrench
8mm wrench
screwdriver with magnetic tip
needle-nose pliers to insert glowplugs
Took 2.5 hrs by spending 45 mins digging out my 8mm from between the pump and block.
-
guh, car still starts super rough, if i plug in the block heater. if i don't plug it in, it don't start. Jumpering 12v to the glow plugs for 5 seconds doesn't help.
-
You've checked that your new glow plugs are getting at least 20 seconds of 12V ??
Glowplugs are one reason why a diesel might be hard to start when cold... but only one.
Timing and compression are the other big two.
-
when using the block heater it starts but starts super rough. lumpy idle for a minute :( trying to find someone local that can check my timing
-
it also sounds raspier about 3500 rpm, like more tin sounding. i think the timings not right.
-
How does it start and run when warmed up?
Did you check the glow plugs were working properly when you installed them?
That's the second reason that I pull the injectors to troubleshoot bad glow plugs, I can easily see how they're all working and how long they cycle just by looking down the injector holes.
-
unfortunately i didn't know how to test them before i installed them. I will be testing the old ones that are out to see if in fact they were dead, that'll be a hint. The new plugs didn't make a difference.
when it's warmed up it runs fine. if i turn off the car and start again, it sometimes takes a lot of cranking to start, like for 5 seconds. didn't used to to that.
-
major props to commuter boy. Figured out my glow plug system was working ok, checked the timing and it was out a full tooth. spent the next 3 hours setting the pump and engine timing.
Drove fine home, a bit quieter, and no different noises at 3500rpm+ like before.
I'll be seeing you again with some goodies!
:D
-
I thought you were going to come out yesterday?
-
I thought you were going to come out yesterday?
i wans't able to make it out to abbotsford, got stuck in langley til late :(
-
Ahh next time just call and let me know, I waited around because I thought you were coming.
-
Well, I don't know if it was a full tooth off or not, but at TDC we couldn't line up the cam and the fuel pump locks and the pump was jammed right up against the injectors.
Not good. I'm more concerned with how the timing ended up that far off in the first place, I'm hoping it's not crank pulley slip. From what I understand your last mechanic was competent, so I'm hoping it wasn't them, though mistakes happen.
It's kind of nice having someone to do all the crawling around under the car for me, I could get used to doing mechanic work like that. :D
-
update today on cold start, cranks up and starts real quick, but it's still pretty rough for about 20-30 seconds. this is with cycling the plugs twice. Maybe i'll try the first cycle til the dome light brightens up again, then one more short one.
injectors have 55,000km on em, the car sat for 5 months over the summer.
