Hello,
Just about to clean engine bay as I don’t think it’s ever been done since new, I know to cover any sensitive electrical areas and not to use a pressure washer and blow the living hell out of it, going to give it a good degrease and rinse.
I’ve noticed this rubber pipe that attaches to the coolant cap it’s only pushed on and is poor condition so want to get a new/NOS but unsure what it’s called, chat gpt seems to say it’s a expansion tank vent/bleed hose bit that pulls nothing on Just Kampers site. It’s a 1986 1.9ltr petrol.

It’s shouldn’t have any clips or clamps, its low pressure vacuum only , so as long as its air tight its good . No need to be braided just needs to not kink and allow coolant through and back
The system is very simple....
The headertank ( the one in the engine bay ) should always be full to the brim, and the top up tank ( behind the number plate flap) should be full to the max mark when cold. When the engine is up to normal running temp the coolant expands and is pushed into the top up tank, when the engine cools down the coolant is sucked back into the header tank

Thanks for that, when I checked the main one I could just touch the fluid when I put my fingers all the way in, so will fill that all the way up, and the one by the number plate was on minimum. It has the pink oat fluid in, I found this cheap online.
