coolant light on UPDATE

[rd070707]

Okay, this is really dragging on now and getting on my tits, so bear with me lol.

Basically what happened is after waterpump change the coolant light came on almost immediately after I picked it up, so I took it back, one of the guys literally fired a load of water in and set me on my way.

This is when I started getting the issue of the coolant blowing out the header tank. We realised the cap seal was off and fooked so I got another cap.

few days later that caps seal was shot too! so I demanded they take it back and flush the coolant out and refill and bleed it. I bought a brand new cap from Peugeot too.

So that's leaves us at today, picked the car up, he said he filled it with water to make sure it wasn't the coolant that was the problem, I drove it home (literally a minute), took the new cap off and ofcourse the level was way too low again!! I stopped the car and next time I started it the coolant light is on!

I don't understand why the level is too low, has he just done it wrong AGAIN?! just to make it clear no coolant has come out the header since I collected it the level is just wrong!

HELP! I was gonna just land it back again but I feel like the reason the seal blew the first time was because the guy topped it up when the light came on and didn't bleed it?
