Mcdevito75 here, I;m sure you mean spark plugs, as glow plugs are for a Diesel engine. -------------- If by chance they are glow plugs and you do have a Diesel engine, I would take it to a shop for installation for 1 reason, the electrical connection on each glow plug is plastic, and in time Plastic gets very hard and brittle, what to do if 1 of those electrical connections break?????. If they are spark plugs, you should buy a spark plug gapper tool available at any auto parts store and get the gap of the spark plugs also the parts store has that info, usuallu .027 Spark Plugs are pre-gapped at the factory but need to be double checked, adjust gap (most likely not need) but if so by slightly, slightly bending the side or Bent electrode on the spark plug tip, Next you"ll need the exact spark plug socket and wrench, also available at the parts store, Let"s assume your set to go, on a cold, cold engine, twist, twist each spark plug wire at the spark plug itself, (as close to the engine as possible) TWIST and pull the spark plug wire off 1 spark plug just 1 . Fit you socket and wrech onto the spark plug all the way, make sure tool is fully on the spark plug, then remove the spark plug, install same way, do not use much force to tighten the spark plugs as they are tapered to fit fairly tight with just a little tightening, Follow this for all the spark plugs and you"ll be good to go. If you have a Diesel engine and indeed glow plugs, let the shop do the job.

Tip

Diesel has trouble starting


hi, if you have any problems starting any type of diesel engine then this is a very good indication that one or more of the glow plugs need replacing, to get you home you can try turning the ignition on and then wait for the glow plug light to go off then instead of trying to start the engine turn it off then back on again, doing this usually gets it started just to get you home but this wont allways work.

Its best you replace glow plugs sooner rather than later as it could leave you stuck without a vehicle.

To change the glow plugs follow these quick instructions.
1. Look where the injectors go into the cylinder head then just under these you will see a smaller plug that will have a fixed wire this wire will be running from glow plug to glow plug this wire is held onto the glow plug by an 8m nut undo this nut on top of all the glow plugs, once undone you will notice that one of the glow plugs has two wires the other wire is the wire that carries the power to all the glow plugs so just remember witch glow plug this goes to.
2. now once you have removed the connecting power wire remember witch way it runs so as to get it back on the right way round it doesnt matter to much but might be a bit tight if you put it on the wrong way round.
3. Now how to undo and remove the glow plugs: To remove you will need a deep 10m socket place this over the top of the glow plug push down to ensure tight fit then undo this glow plug will then pull out (make sure their is no muck around the glow plug that can fall inside the cylinder so just check)
once you have it out its best you replace all the glow plugs as once one goes you will find that the others wont be to far behind.
4. Fitting new glow plugs. When your fitting the new glow plugs put them into their hole and gently screw in by hand to make sure you dont cross thread the thread as this can be a nightmare to put right. tighten the glow plugs in as much as you can by hand then nip them up using 10m socket and extension bar now dont over tighten them as this will damage the thread just tighten up till just after they stop then you should find they are ok.
Refit the wire loom on top of all the glow plugs remembering to fit the main power wire to the first plug make sure you tighten the nuts up properly on top holding the wire in place.
Once you have done this you are now ready to start your vehicle you should now find it starts with no problems.

If you still have problems starting you need to now start looking at things like the diesel filter or even the diesel pump, ill explain about these in my next post ok

Starting problem on kangoo


Check the big fuses in the power distribution box under the bonnet ,this is a UK reg vehicle kept outside no doubt and these fuse connections under the bonnet do get damp ,if still no joy for whatever reason then but a manual push button starter switch and wire them in direct manual overide ,power to switch then direct to the glow plugs ,so when the light dont come push button in for 10secs and no more and away you go,Clean the big fuses and spray with some 3in1 or a oil can with engine oil not that wd40 and lubricate the connections where the fuses push into.

Hi i need your suggestion about replacing the wiring harness. complaint is MIL glowing contineouslu ,and tested with scan tool.it shown as fuel heater problem and 1 st glowplug fault .dealer says...


There is not much information to go on. You didn't say what your vehicle is, what engine it has. Judging by what you wrote, the dealer got a fault code for the glow plug, but didn't change the plug. Instead, they want to put in a new wiring harness, even thoughthey got continuity. I think you need to take your vehicle someplace else and have a qualified mechanic look at it. At least, put in new glow plugs to see if that helps.

1997 Jetta: glow plugs not working. Glow plugs tested good, ne...


Before you invest in a long drawn out Glow Plug replacement etc. A little known issue occurs on the ALH TDI engines. The temperature sensor sending unit. A small blue module that plugs into the coolant hose assembly will cause a P error on the glow plugs that is nothing to do with the glow plugs at all. The part fails and sends a temp error to the engine computer. I tested all the coolant glow plugs, engine glow plugs and glow plug harness and all worked fine. One of the test procedures for the glow plugs is to undo this sensor that will force the glow plugs to come on no matter what temperature. This confirmed my GP system was functional and the sensor was bad. I purchased the part from local VW dealer for $33 US and installed and it is fine. Dependent on your model it can be square or round. The link to this part for your car is http://www.partsgeek.com/catalog/1997/volkswagen/jetta/body_electrical/water_temperature_sender.html

Be sure to have VW Pentosin coolant on hand to refill coolant system as you will lose quite a bit when removing this part. It is located slightly behind the coolant glow plug assembly.. This is the round ones not the ones on the engine block at top.

Be sure that when you replace it you put in a new rubber gasket seal.. its a round rubber seal that should come with your new part. Dont reuse the old one or you will have a leak.

There is a c-clip that holds this in the hole you slide that clip off and wiggle the sensor out. Coolant will run out of the hole, so do this outside. The sensor is easily pulled out. You will need to insert the new part in teh same hole with new rubber gasket and replace c clip. Then plug in wiring harness and you should be good to go.
