Anyone Know How A Skyline Heater Works - R32

[kristafa]

i'm reinstalling my rb20 into my bmw and want to now hook up the heater coz its friggin cold lately.

// apologies for my explanation, hope someone gets it

I need to know, in the skyline does the heater control a solenoid that is shut when the heater is off (and stops the flow of coolant altogether, not returning it to the block), and open when the heater is on? or does a solenoid just divert coolant from the solenoid back to the block when the heater is off (ie coolant continues to run through to the motor even when the heater is off?)

i know in the bmw when the heater is off, the solenoid will just block the flow of coolant to the heater, and there will be no flow back to the motor...

i just dont wannt cook my motor - i'd been running a 'U' shaped heater hose that connected straight from the heater outlet to the inlet on the rb20 block.

thanks for any help. chris.

when the heater is off, a valve at the entry to the heater radiator is closed, stopping the flow of coolant into the heater and back to the block. The coolant only flows back to the engine when the heater is on.

Im not sure what its like on a R32 but on R33s coolant runs through the heater all the time. There is a flap on the heater box (not the heater core) which opens to let air flow through to be heated by the heater core. Ie. When you have the temperature set to cold the flap on the heater box is closed.
