streetkit Posted December 29, 2003 Share Posted December 29, 2003 Please forgive the stupid question, but I'm new to these awsome cars. I have a 92 SC400 that i am trying to get aquanted with. Which if the two radiator hoses is the return line back to the radiator? The upper or lower hose that comes up to what appears to be a thermostat housing?

K9crew Posted December 30, 2003 Share Posted December 30, 2003 streetkit, that's a good question ... the photo shows the coolant inlet fill plug next to the thermostat housing. The inlet hose from the bottom of the radiator (out from the radiator and into the engine) is connected to the thermostat housing. The other hose that's connected to the top of the radiator is the outlet hose (from the engine). :) Quote Link to comment Share on other sites More sharing options...
