I own a 2003 BMW, which doesn't need the timing chain replacing according to my garage. Do you agree?
The water pump, radiator and timing chain on my 2003 BMW E46 Touring (with 123,500 miles on the clock) have never been changed. The expansion tank was replaced in February 2019. I asked a local, independent garage about it at my last MOT and service, but they said the water pump and radiator were in very good condition and the timing chain should be okay providing that oil changes are carried out regularly (every 4,000 - 5,000 in my case). Should I be unduly worried about the age of the water pump and radiator?
The garage is right about the oil changes (as long as the oil is kept clean the chain should be fine). Replacing the water pump will require the chain to be removed. I think the garage is giving you reasonable advice (water pumps on chain-driven engines are usually durable and can last a long time). But it's impossible for me to say if you should change/keep it without actually seeing the car. If you're worried, I'd suggest getting a second opinion from a BMW specialist. You should be able to find a local one with our Good Garage Guide: good-garage-guide.honestjohn.co.uk
