Hi All.

 

I have just been flushing the heater core in my EJ22 and I cannot remember which hose goes to which connection at the engine.

 

There are two steel hoses coming out of the engine (a top one and a bottom one separated by about 2 inches) which one goes to the heater core and which one is the return?

 

Cheers guys.

It doesnt really matter, as flow through the core will be the same either way.

 

When installed correctly the hoses will sort of lay parallel to each other, one just above the other. If they look like they're crossed or twisted or they don't look like they're right, swap them and see if they look better. They shouldn't actually touch because that will allow them to rub together and could cause them to rub through and burst.

Thank you!
