Thermostat, hoses & clips for install.

The thermostat is fitted behind the expansion tank.

The hoses are attached…

and the radiator bottom support bracket is installed…

Once the radiator is fully installed I can check the cowls fit properly.

As you can see there is some trimming that needs to be carried out to make sure the cowl doesn’t foul the radiator.

Looks ok from the front.

The exhaust seems to clear the cowl however another check will be made before final assembly. The gascolator is located on the opposite side to the exhaust pipe and requires a hole to be drilled which will enable fuel checks to be carried out before flight.

The installed thermostat with just a ‘stand off’ to be fitted to make sure it doesn’t rub against the adjacent engine mount.

Now the cowl fitting has proven All the clips are fitted – job done.

I purchased a Kavlico EMS kit so the EGT sensors need to be installed.

A 3.2mm hole needs to be drilled in the rear exhaust downpipes 4″ from the flange.

Once the hole is drilled and sensor fitted it is held in place with the supplied, modified jubilee clip. The sensor has a ‘collar’ that ensures that the hole is sealed.

The downpipes are re-fitted and re-wrapped, securing in place with stainless steel ties.

To ensure the springs don’t fall and cause a runway hazard if they fail in service they are wire locked. Tomorrow I will fill the centres of the springs with heat resistant silicone which reduces any resonance from the springs.
