Heater hoses
 

I have a Volvo Penta AQ125A engine in my boat that I want to connect heater hoses and a heater core to. This is a Volvo based B21 "red" engine as in the 240 series. Where do the heater hoses come off the block on a Volvo 240?

Thanks Mark..........

there is a red pipe attached to the waterpump which then connects to the hoses to the car. then from the car back into the intake manifold under the fourth runner.

wait for the experts to get on.
