Title: Coolant seal replacement
Post by: oldrotary on June 29, 2008, 08:38:51 PM
After just one years running my coolant seals have failed. I have pulled the motor out and started stripping it down, but am having a problem undoing the eccentric shaft lock bolt. I have tried a long tube through the spanner to give more leverage, together with penatrating oil, but it has not moved yet. Can anyone confirm that this is a conventional right hand thread? Is this a typical problem? I have had problems with some of the other bolts but they all moved in the end with just penetrating oil and brute force.
Having removed the water pump I am amazed at the condition of the water ways, they look new, but I am more used to much older cars, is this typical of the passages around the water pump and front housing?
Regards John

Thanks for the reply. I will try again tomorow night after the penetrating oil has had a chance to work.

afraid they are usually a pain in the rear.  They should be thread locked too which causes the annoyance but rather that then the bolt coming loose while in use!  I just had the blue coolant colour in my waterways :)
