As per title.
It's little strange tho, because it only happens once the engine reaches running temp (while driving), then it spits water/coolant up onto the passenger side of the windscreen, then stops. This happened last week on the breakfast run where I did around 300 miles & no further leakage, so header tank level is still good.
I have the car booked in for oil change service and I have mentioned to them about doing a pressure test.
I have my 1st track day booked on 9th June, so not sure whether to keep fingers crossed & hope it holds, or look into replacing before. (Will be gutted if it pops on the track day!!)
I also have an AA parts & labour warranty, so maybe if the pressure test fails I could make a claim!!
