Availability: in stock


Quality Optibelt product. 11.3mm x 912mm V-belt. Designed 1200cc–1600cc aircooled engines fitted with an alternator. Fits Beetles from 1973 to 1998, T2 Bays from 1974 to 1979 and Brazilian made Bays. Don’t miss our video on checking and replacing the belt should this happen to you.

Don’t get stranded – carry a spare!
Aircooled engines rely on this belt to drive the generator and, in turn, the cooling fan. A snapped belt will quickly result in a very hot engine. A slipping belt will also result in reduced cooling. Be prepared: for just £5, this ‘insurance’ offers a very good deal!

    • i am replacing the alternator belt on my 1600 type2 bay and have purchased the 11.3 by 912 belt but it is to long any idea why ?
    • Answer: Some aftermarket top and bottom pulley differ in diameter etc. Also some of the aftermarket alternator stands differ in height. I take it you have 10 shims between the top pulley halves? Failing that you could try a dynamo belt
