I am getting close to where I can install my 2.1 wbx engine.   New pulley is installed as well as the exhaust system, heat shield etc.   Still short a couple of small parts.
Its sitting ready to go in but I still have to get the clutch release mechanism checked out and the new throwout bearing installed.
The coolant that was still in the engine was dark green in color, a bit like British racing green, not a generic antifreeze.    Does this sound like the right kind of antifreeze?     Is the pink VW antifreeze that I use on my Tdi ( G12) suitable for use in this engine or should I look for something very specific?

I need help with a couple of parts:

The exhaust "J" pipe has a port on the underside, near the catalytic converter.   The cap is missing from this.     Does anyone know a part number for this cap or what thread it is?    I'm thinking I should probably just weld it closed or tap it for a close off screw..

There is a hose that goes from the breather tower over to the intake boot.   There is a barbed fitting that fits the hose and the boot.   I am missing this barbed fitting.    Does anyone know the part number for it?   Its a bit bigger in diameter than the 3/4" one I found at Lowes.

The big heat shield has some holes each end where side plates bolt on and fill the the gaps between the fuel injector areas and the inside wall of the engine compartment.   I am missing these plates.    How important are they?     Do they do more than just stop dust etc from blowing up into the compartment?

Thanks for any help.  Steve
