Seen some people have completely removed the incar heater unit and bypassed it all together. I want to do the same, couple questions,
Apart from heating the inside up (when they work) any advantages or disadvantages to removing.
is it a case of removing the heater and linking the two pipes together
Do I need to extend the pipes to make up for loss of coolant that would of been filled up in the matrix.
Thanks micky

I simply removed mine and linked the two pipes.
Youíre losing extra water capacity from the cooling system, so if your current cooling is marginal removing it wonít help matters.

Downsides ?

No heater, and no means to clear the windscreen ( even if it isnt great anyway lol )

IMO given how little it weighs in a Mini...I can see few benefits to removing it.

speed didn't kill me, but taxation probably will

No sure what the car is used for but IIRC here in the Nethererlands we need a blower / demister in for the Dutch equivalent of MOT...
(Eventhough it only blows air on the windscreen rubber)

Heated windscreen is the way forward if you remove the heater.
