New here,but already found a lot of great info.I have a question hope someone can answer.I have a 92' Eldo w/4.9.The heater hose going from thermostate area to heater has a "T" in it with the other hose going to the waterpump area. The plastic "T" broke & I had to replace it.The problem is which way does the arrow point to? I'm not sure if I have it in right or not.Thanks........Bob

That "won't get much heat" comment intrigues me - mine broke on my '92 Seville - and I had to replace it with a non-OEM "T" fitting (it broke on a Sunday) - so there is no restriction - guess I'd better stop at the dealer and get a "real" "T" fitting!

The arrow points towards the heater core. It should be pointing to the end with the restrictor in it.
If you look inside it's really just an orifice that's a little bit smaller than the other opening.
