Your billboard size photo isn't very helpfull. Reduce it t0 800 pixels wide and try again.

The pressure cap isn't responsible for a burst hose. I'd say there was insufficient coolant circulating and the engine overheated very rapidly causing a pressure surge. Having said that, the 1.8 hoses aren't the toughest.

That's the standard failure mode for 1.8 top hoses, along the flashing seam (where the 2 halves of the die met when the hose was made).

Nothing to do with the expansion cap, everything to do with age. Just ask MGJohn!

Actually the turbo model hoses are made from a rolling process sort of rollypoly style.

They are much more fragile than the standard nasp 1.8 hoses.

The later hoses made by the Chinese are far superior compared to the originals.

The inside of the burst hose looks a horrid orange rust colour, indicating that it may have just been water in the cooling system

I did a reverse flush 2 weeks ago the NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- that came out you wouldn’t believe as the passenger side heater was only blowing out cold air heater now working on both sides topped up with antifreeze bled the system been running fine no air locks I’m baffled pipe should be delivered today so I will top up and see what happens also going to replace the cap
