have recently found out that the mix of coolant to water was most likely incorrect in my cooling system. when i bought the mix from the dealers the sales guys told me i must just add the coolant and top up with water. that is what i did but now it seems that was incorrect advice.
upon closer inspection of the bottle yesterday it was discovered that what they had sold me was a premiex product and must not be diluted

. the whole system ( and all top ups) must be be done with that product only.
i assume this could potentially be the reason why the cooling system has been behaving strangely with overflow bottle filling up etc?
any ideas?
I am hoping that is the case......this has been a long and expensive voyage of discovery so far....
