How do i drain my engine
Need help i want to drain my engine,rad etc of water/coolant how do i get all water out? Is there a plug?
|
usual way is to remove the bottom rad hose from the rad or block and the expansion tank cap - make sure the heater is set to hot
|
Im old school, so I would suggest uncliping the bottom hose from the rad ;)

Still should set it to hot when purging air out of the system (purging = running the engine with the header cap removed ;) ) after refilling, to assertain if there is any air lock and satisfy that coolant is actually flowing through the engine.
Oh yes and fill the sytem V E R Y S L O W E L Y ! (give rad both rad hoses a few squeezes whilst doing so) Fill header tank to 3/4 full to allow air to purge and prevent overflowing when running the engine with the cap removed (topping up as and when). |

My point is that the Subaru heater circuit doesn't use any valves to control the water flow through the heater matrix (as with some/older systems) and will not trap fluid when draining, or air when refilling. |
