Is it a big job to replace an Astra's timing chain?
Is it a big job to replace a timing chain on an Astra ? How long does it normally take ? Thanks in advance
Our answer:
Hi Anthony,
Replacing a timing chain in any car is a pretty big job, taking most of a day really start to finish. Each and every engine is a little bit different though depending on how crowded the engine bay is and how much dismantling is required.
