08 RRS 4.4L Where Are Block Coolant Drain Plugs?
Can anyone provide a pic or diagram of the location of the engine block coolant drain plugs for an 08 RRS 4.4L?
I'm replacing the thermostat housing due to leaks. I drained the system using the lower radiator hose (no radiator petcock on 08 4.4L) however only about 1 gallon drained, just the contents of the radiator I think. Both the inlet and outlet are on the top of the engine so it didn't drain the block. The coolant level is still well above the water pump visually by looking into the existing thermostat housing. I don't want to remove the housing and spill a gallon or two of coolant all over the top of the engine with the the throttle body removed (which is required to remove the T housing).
Tough to find info or vids out there for 08-09 RRS 4.4L. They all just say drain the system by removing the lower radiator hose. Any help would be appreciated.
Thx!
