Very Important! Don't just replace the rubber hoses, make sure you also replace the Quick Connects. If you buy OE, then the Heater Hoses come with new Quick Connects. If you buy aftermarket, then the Heater Hoses don't come with new Quick Connects, you have to buy those separate. Those are plastic, and blow out, so you need to replace those as part of the Heater Hose replacement. The Quick Connects are what connect to the aluminum heater core nubs. Then the rubber hoses connect to the Quick Connects. The Quick Connects click on in 2 seconds, but they take 20 minutes of fighting to get them off. You basically have to break off or bend out those two little white plastic (yellow plastic on OE) clips that are right near the firewall. What make this hard is that you have to break them or bend them out, while not damaging the aluminum heater core nubs. So it takes about 20 minutes to carefully do this. Once you have battled them off, then new ones just click on in 2 seconds. So I call them "Quick Connects"/"Slow Disconnects".
These are the only hoses I bought aftermarket, because I did them two weeks ago. So this picture is of the new Quick Connects and new Heater Hoses. The shorter of the two Heater hoses that goes down to the engine block was all bubble up and soft, ready to blow. Both Quick Connects were leaking and crusty, also ready to blow.
One of the Hoses goes straight down to the back of the engine block. That one is right there and easy to get to. It helps to move the Power Steering reserve out of the way to get more room to work, two bolts to move that over. The other Hose goes along the back, then turns in towards just below the Throttle Body. If you are only changing the Heater Hoses, you don't need to strip down everything to the Throttle Body like the pictures shown earlier. All you need to remove in that specific case is just the Battery, then you have access to this Hose. Everything is striped down in this picture, because I was doing the Throttle Body Hoses. But when I did it two weeks ago, I only removed the Battery to gain access to this spot. Also, you see that protective sheath about midway in the hose. They sell that separately from the Dealer, but I just slipped it off the old hose, and slipped it onto the new hose, it is reusable. I think the reason it is there is because it rides just under the rear intercooler, and it would potentially rub on the intercooler fins that would act like a knife over the years and cut the hose. The intercooler has been removed in this picture, but you can see from the where the connection for the intercooler is that it would be touching and rubbing this hose. So you need to put that protective sheath back on the new hose.
