Anyone know where the heater inlet hose is on the 2003 Impala LS? I
want to flush the radiator but with out knowing where that hose is I
can't splice on the flush kit.

Here is a picture of the two hoses in the back of the engine. I think
it is one of these as they both go back to the coolant system
(squeezing them causes the reservoir to bubble).

Anyone know which one I am supposed to splice the flush kit onto?

This is not as easy as my past two cars! The diagrams I have from the
service manual do not match the engine at all.

The line into the core is the hotter of the 2, use that one.

The hoter of the two?

Why would that be so?

The hot hose is the inlet to the core, the return would be cooler as the
coolant going through the core ( which is like a small radiator) is cooled
as it returns to the engine, there will be a more pronounced difference in
temp with the heater on and the blower on high.
