KAD 44 coolant change

[simonfraser]

Just drain and fill ?
I have extensions to a heat exchanger for air heating and a calorifier
Do an in between rinse, which would be with tap water, not distilled .....
No probs with overheating

Where is the best place to drain it, the extension hoses are more accessible than the KAD drain plug

Will it just fill from the top reservoir, or am i gonna get an air lock and not filling / cooling ?

Bear in mind there are now two Volvo coolants and you can’t mix them. Green and yellow I believe. If you do swap it requires an oxcalic acid rinse and the engine must be compatible with the other type.

I bought Volvo but at long as you don’t mind a colour change you can save many beer tokens.
