How do I change these on a NAD couple look very difficult to get to
yes fiddly....good socket set with a flexi extension and a good spanner or two will see you well.
magnet too for when you drop the dumbass tiny heater plug connections nut down behind the pump!!!
Are there any brands that I should buy or avoid when buying glow plugs ??
ngk, bosch or denso all good.
In 7years of maintaining pugs NGKs have never failed me
lil bit of grease on new threads wouldnt hurt too....
NGK's failed epically on my HDi last year.....Bosch every time
Bosch Duraterms, less than £25 for 4 on Halfords trade
Trouble is I don't get trade prices
