Like I've said in some other posts, it's been a LONG time since I've been under the hood of one of these.
I don't remember ever seeing one of these before, but my lower heater hose has a canister . What on earth is this for? the heater hose goes into the canister, then a hose comes out of the canister and goes to the bottom of the radiator.
It looks like crap. What is it?
