Cooling System

I have the GBS water rail and cooling system.  The first job is to smooth the powder coating on the thermostat housing in order to get a good seal against the engine block.  Rubbing the hounsing on sandpaper on the work bench worked well:

I noticed that there was a lot of sand in the water rail from the manufacturing process:

It took some scrubbing down the tube to remove it, but better than allowing it to run through the engine!

The water rail is easy enough to fit, but the front bracket also holds the dipstick and the dipstick can only be fitted after the exhaust, so it can remain loose initially.  I fitted 4 rivnuts for the header tank to the rear of the LH engine mount and fitted a rivnut for the engine earth lead whilst I was there:

The radiator was fitted, noting that there are two sets of mounting points: one set on the front of the rad the other set on the rear.  The rear ones need bending so that the radiator can be mounted using the front set otherwise the nose won't fit over the radiator.  I used 4 mounting points for the rad as shown below, the plastic brackets were sanded slightly so that the fan sits flush onto the face of the rad:
