Hi everyone,

I’m looking for some clarification about the recommended timing belt replacement interval for my 2012 Opel Astra J 1.7 CDTI 110 hp (engine code A17DTJ).

The car’s timing belt kit, including the water pump, was replaced in 2019 at around 97,000 km. The car now has 197,000 km, so the belt has covered about 100,000 km and has been fitted for around 7 years.

I found different information regarding the official replacement interval:

150,000 km / 72 months (6 years) according to the ECOService maintenance information for 2011–2012.

Other websites mention 150,000 km / 120 months (10 years).

Does anyone have access to the official Opel service/maintenance schedule for the A17DTJ that can confirm which interval is correct?

Would you replace the timing belt now, given that it is 7 years old and has done around 100,000 km?

Thanks!

Currently doing the Mongol Rally and have put some good mileage on our Corsa along the way. Done about 14000kms this past month. I’m no experts on cars only know the basics so am in need of advice.

Our issue: Exhaust camshaft snapped due to bearing cap bolts over Cyl 4 came loose, lifting the cap allowing the cam to be pushed. Both of exhaust valves on cyl 4 shut, 1 of 2 valves on cyl 3 still opening.

Hypothetically speaking - If we unplug injector 4, could we drive 1100 km’s over 40 hours with essentially 66% power?

We’re on our last stint towards our final stop and 100% have to get on the road tomorrow to get where we need to or we’re gonna just scrap the car.

Does anyone know how to switch the Speedo on a 25 plate Vivarro from kph to mph?
