Title: Grandland 1.2 cambelt problems
Post by: Migv6 le Frog Fan on 26 December 2025, 10:39:42
Had to feel sorry for our maintenance bloke. He just turned up at work to borrow the company Dacia Duster because his Grandland packed up on him yesterday as he was on his way to spend the day with his Daughter and Grandchild.
He sat at the side of the A12 for five hours until he got recovered home.
He says the recovery bloke diagnosed the cambelt has jumped teeth, which was why the engine died.
Its four years old and he bought it 15 months ago. Its only covered 55 thousand miles and  he says the interval is supposed to be 100 thousand.
Hes thinking about spending a couple of grand or so having a recon engine fitted.
Dont suppose anyone knows much about these little contraptions ?
Safe engine ? Worth fitting another belt and timing it up to see if he got away with it ?
Personally I think I would be having a bloody good moan at Vauxhall as it only has 55 thousand miles on the clock.

Is this the 1.2 three cylinder engine with the dreaded wet cam belt? There was a recall on them a while back due to premature cam belt failure. They require meticulously maintaining the oil changes schedule (specific oil as well) but still no guarantee that they won’t go bang.

The belt running in oil degrades the belt prematurely, with belt dust getting in all sorts of places, the oil pick up, the turbo and vac lines to name a few. The belts either snap, or strip teeth when the starter swings over. There have been enough cases of belt failure now to prove it’s a shite design but still manufacturers insist on going down this route.
The joke is that they tell people to have the belt inspected regularly. How the bloody hell are garages  supposed to inspect a belt when it’s fitted internally. By the time they’ve stripped down the covers and gaskets etc., they may as well just fit a new belt.

Yep, shitty little engines. Four pot diesel is the one to go for.

Yep, its one of those engines. Dont think he has the service history exactly as they would want it, to try and claim so he has learnt an expensive lesson by the look of it.

It's in a lot of Stellantis vehicles, Peugeot and the like.

The lad across the road works for Stellantis, apparently there is go-no go gauge for the belt. As above, what a stupid idea!

Correct, they check for belt wear through the oil filler hole on this engine. What it doesn’t show is the fine belt dust degradation and fine fragments that clog up the oil pick up, which in turn starves the engine of oil.

This clip shows the intricate ;D tool for checking the belt width only. One can only assume that if your belt width is out of spec, you can turn the tool around and use it for blowing bubbles to amuse yourself while you ponder what to do about it. ;D

Think you are right STEMO . Diesel fairly simple.

What were the engineers thinking with a “ wet belt”!

I’ve just watched a clip of one with stripped teeth at just 25K miles.  :o  The belt width was within spec.

That checking tool looks a complete load of shoite
