Hello everybody from Barcelona

Firstly congrats for the forum.

Let me introduce myself, I have an Escort RS Turbo S2 form 89. This has been my first car, and now is the Sunday’s car. However, my RST have little problem. For every day I drove a SEAT Cupra R.

Let’s go to the “work”

1.- I’m going to change the rear brakes. I think the drum diameter is 228mm. Is it ok?
2.- Somebody said to me that its possible to mount directly the caliper of a Sierra in the Escort, is it true?
3.- in other way, I have a leak in the thermostat housing, See pic


Is that part of the housing a cap or smth like this???

Thank you for your help
