Its a fairly simple job to do, BUT, if you break them it could cost you a lot of money. Worst case, the head has to come off.

Do what I did, give it to a European dealership to have them replaced. If one does break, they have the experience to complete the job.

Why do you want to replace them?, and what indications do you have?

And be prepared to have a heart attack if you buy glow plugs from Suzuki. I'm talking around $160 each.

Again, go to another dealership or parts specialist. Get 4 Bosch glow plugs, at around $60 each.

Hello and thank you for your reply.

The reason that I want to replace these is that the lamp for defective glow plug displays on the instrument panel.

I bought 4 Denso glow plugs, assuming that these acts.

Ok, i had a dash light on also but had to get the fault code read by Suzuki. Mine was also harder to start when cold. I had to turn the ignition on twice for a normal start, even 3 times during winter.

If you take the top cover off the engine, you will see the 4 x plugs. Pull of the wire connectors and take them out like a spark plug.
They are much narrower, so good luck and don't break them ;)

Hello and thank you for your feedback!

Have now installed new glow plugs and now there is no warning lamps in the dashboard.

Obtained a service manual where all this was described.

Petter
Hi, can you share the service manual you used, or let us know how/where to get one, I need to run a compression test on the engine and I need to remove the glow plugs to install the manometer feedlines

I can only find 3 glow plugs, all set together,and not above each cylinder????
Then you're not looking at glow plugs, there's one into each combustion chamber
