I took my 2nd attempt at flushing my coolant system today. Flushed the rad again and flushed the filler bottle now i know what its for! I was firing water into the filler bottle at pressure and watching the dirt come out of the small overflow pipe into the rad, then once it was clear i flushed the rad again. I then realised that there was loads of water going into the filler bottle but not much coming out the top!
I then looked under the car and to my horror saw loads of water pouring out of the underside of the car below the water bottle! I had a feel around and i think its coming out near the top on the neck somewhere. I then thought well I must have just broke it as the car never lost water before. I then thought sod it and filled the system. Started the car and turn the heater on full. I then kept squeezing and refilling till i just got clean water and no air out of the bleed valve on the top of the rad. I let the car run for a good 20min and took my time doing this.
I then sealed the rad and turned the heater down a bit, left it running another good 20min and the temp sat at a steady 155F (68c). I then turned it off and sat watching the bottom of the filler bottle. Got a few drips but they were cold (not from the main system) probably just left over spillage.
I then tried to pit a bit more water in the filler and it just pissed out again, its reading high on the dip stick thing. By the speed it was coming out I would say that its not a crack and when I put just coolant in it a got just coolant leak out. So has the bottle got an over flow/breather or is it buggered (hole near the top)?
I left a cat bowl underneath it so i can see how much it has leaked in the morning.
Is the filler bottle pressurised? Any answers please?!
