Why would a mechanic crank heater to maximum

Why do I need to turn my crankshaft after installing a timing belt?

Yes, it's absolutely necessary. As you state, the primary purpose is to check the timing. It is far better to do this by hand and ensure the timing is right rather than to start the engine without it ...

The engine in your Renault is more than likely an interference engine. What this means is, if something were to happen to the belt, the engine will be history. This would leave you stranded, more than ...

Unfortunately there is no magic eight ball which can tell you how many miles are on a timing belt. This is my own opinion, but I'm sure it's shared by most: If you don't know the mileage of a ...

Is my timing belt looking bad?

There is just about no way to know the viability of a timing belt by looking at it. Your belt could last another 100k miles or it might pop tomorrow. This is why it is important to follow the change ...

Is it safe to start the engine after rotating crankshaft by hand(using a torque-wrench)?

If you are worried about cam timing and lunching the engine, if you've not taken apart any of the cam timing components (belts/cogs/tensioners), you've done nothing to cause you issues. I think the ...

Should I replace my timing components when I replace the water pump?

I would say you should replace the belt and tensioner while you are in there and everything is apart. If you really want to put the old belt back on I would consider: How close the vehicle is to the ...

Why does this mechanic change the crankshaft mark, during this timing-belt change?

The simple answer to this is that you can make any marks you want on the pulleys before you take the belt off. As long as you put the belt back on with the pulleys in exactly the original position as ...
