hello,

need some advice, as I don't need heater in my tropical country.

can I deleted heater matrix by not use it and just block the rear cyl head hose pipe and other rubber pipe? or better to connect and by pass it?

my engine is m20.

thank you

Dont block them, run it through to the rest of the system as the heater would

link together the two pipes that go into the bulk head.

That was my first reaction as well, but if the heater knob is on full cold, the electric valve is closed, and there's no flow anyway.
Probably easier to join the pipes though, rather than block them, and it would lessen the chance of an airlock in the head when refilling the system.

Yep, also reduces hot spots at the back of the head
