good morning,
i have to exchange my "cooler hose".
up to now I ever used the red coolant colored fluid
but i have heard that i should use an other colored fluid
for the cooler hoses - when I refill the whole system.
which colour should I use - or ...
do i have to use the green colored fluid in the coolant and also
in the surge tank ...
sry for my poor english - hope u have an advice
thx in advance, stephan
