Under bonnet sound proofing

[Craigybaby]

Evening folks, hope your having a good weekend. i seem to remember later s2s didn't have any sound proofing, and mines a j reg, so what's that scruffy looking 5 x 5 inch bit under my bonnet for near the middle?
While I'm at it, is the expansion tank for coolant? I only ask cos mines got a sticker next to it mentioning air con. Is coolant a simple case of blue or pink and don't mix them? Mines blue, so just need to top up with blue?
Regards

It is for coolant, yes. Underbonnet foam was deleted during 1988, I think.

Just for clarity - When you are standing in front looking at the engine - coolant expansion tank is to your right. Windscreen cleaner is to your left. Windscreen cleaner is often blue also but I have seen pink and green. Unfortunately antifreeze can be any of those colors also. Just to be sure - the expansion tank has a pressurized cap while the windscreen cleaner just has a pop on plastic cap.

Correct, Porsche dropped the under-bonnet sound proofing for the later cars. Most seem to have (or have had) a lonely square of foam padding in the area that would be over the distributor when the lid is closed. As to why, I have no idea.
