We had a Citroen DS3 in recently for Wetbelt replacement and coolant change, unfortunately when bleeding cooling system up we had heavy signs of head gasket failure not the best news but that’s where we are here to help, whilst we was fully booked we managed to fit it in around jobs and just to go that bit further for the customer we didn’t charge them the initial labour for the wetbelt replacement but just the labour for head gasket replacement

All work comes with 1 year / 10,000 miles parts and labour warranty

Are you are worried about your timing belt/timing chain or don’t know when it was last changed?
Speak with us today and see how we can help you with your vehicle
don’t hesitate to get in touch as we accommodate to all makes and models and can advise you accordingly
