The torque specifications for the flywheel on a Nissan Tiida 1.5 litre can vary depending on the exact model and engine type. I would recommend consulting the factory service manual for your specific vehicle to find the correct torque specifications.

However, as a general guide, the flywheel bolt should be tightened to a torque specification of around 50-60 ft-lbs (67.9-81 Nm) using a torque wrench. It is important to check the service manual for the specific torque for your flywheel and make sure the bolts are tightened in the correct sequence and pattern.

The torque specifications for the flywheel and clutch on an Opel Astra 1.4L 2012 with the A14XER engine are as follows:

1. Flywheel bolts:

• Stage 1: Tighten to 20 Nm (15 lb-ft)
• Stage 2: Tighten an additional 70 degrees (or 2/3 turn)

1. Clutch pressure plate bolts:

• Tighten to 22 Nm (16 lb-ft)

It is important to use a torque wrench to ensure that the bolts are tightened to the correct specification, as over-tightening or under-tightening can cause damage to the components and affect the performance of the vehicle. Additionally, it is recommended to use new bolts when installing the flywheel and clutch to ensure proper torque and avoid any potential issues caused by worn or damaged bolts.

8v or 16v engine?
The latest torque value is often supplied with the replacement head gasket.

You should verify these figures from an official source but with any stretched or corroded bolts replaced and with all male and female threads thoroughly cleaned and lubricated along with the washers and under the bolt heads, the bolts are tightened in stages in a spiral pattern working outwards from the centre pair to an initial torque of 18 lbft.
As an example, many of the 8 valve Vauxhall/Opel engines are then tightened by 60 degrees + 60 +60 and then after a thorough warm up and at least 6 hours cooling the bolts are tightened a further 30/50 degrees depending on "feel".

Vauxhall/Opel's 8 valve 2 litre ohc engine, working from memory - the initial torque starting from the middle pair of bolts and working outwards in a spiral pattern is 18 lbft.
This is followed by further tightening in stages of 60 degrees + 60 + 60.

After thoroughly warming up and allowing at least 6 hours cooling time the bolts are tightened a further 30 - 60 degrees, depending on "feel".
Stretched or corroded bolts should be replaced, all male and female threads should be thoroughly cleaned and lubricated as should the washers and under the bolt heads. Starting after rebuild is easier if the hydraulic tappets are emptied of oil prior to refitting.

The current tightening specs are usually provided with the replacement gasket.

normally 110 nueton metres. use nut lock and once you have torqued you will feel if you have to tighten it a bit more.
