[Rackned]

Has anyone got any info or photos of the difference between the Mk1 and MK2 inlet manifold?

thanks in advance

Mark. Remove the thermostat and look behind it..If there is just an open cavity, it is a Mk 1. If there is a round hole through a ledge in the casting, it is a Mk.2.

Ok thanks but I suppose the right question then is does it matter if there is a difference between a mark one and two and if so what is it?

Hello Mark,

As Mike (Lingen) said, the difference is inside the thermostat housing, which in turn determines which design of thermostat may be used. The Mk2 stat has a disc, which locates in the bypass hole that Mike mentioned.

So nothing that would be a problem what swapping, other that the thermostat?

The Mk1 doesn't have a way of shutting off the bypass( that's what the foot on the thermostat does) so some of the coolant can always bypass the radiator with the mk1. I know which one i would have.
