Questions about crankshaft pulley replacement

How long does crankshaft pulley replacement take?

Usually about 1.5 hours. Your mechanic will tell you if your car needs longer.

Can it be done at my home?

In most cases, yes. Mobile mechanics need a safe, level place to park, such as a driveway or quiet street. If your job needs a workshop we'll let you know before you pay anything.

Is the price fixed?

Yes. The price on your quote is what you pay. If the mechanic finds something else, they'll explain it and give you a separate price – nothing extra is done without your OK.

Is the work guaranteed?

Yes – parts and labour are covered for 12 months. See our guarantee page for the details.
