Hi Group,

Is there a specail tool that is used to remove the allen hex water pump bolts on 96 C280. 6mm allen hex seems a little large for the bolts. Could this be a 6mm allen hex head with corrosion that is causing the problem or will I need a 5.5 allen hex head? I want to be absolutely sure of the size.

It is my understanding that these bolts can be a problem to remove and I want to use the very best tool and technique the first time around. I have also heard using valve lapping compound on the tool may help prevent slipping.


Thanks
