Hi, I got a new problem trying to fix another. So I was trying to replace the PCV valve and I accidentally (barely) bumped into the smaller coolant hose that goes into the right (passenger side) of the firewall, and the metallic part of the hose looks like it was corroded and snapped. it's an extremely hard to reach area and the other end of the hose is even worse. So since it apparently looks like it has a special quick disconnect on the end that goes into the firewall. what would be the easiest way to go about replacing this? Do I need a special tool or can it disconnect without it? And also since the other end is in a nightmarish spot could I just cut the hose so far down and use a coupling to connect a new hose to the old one? I'm pretty much stuck until then. thanks!

Hello again,

In the diagrams down below I have included the directions for the removal and installation of your vehicle's heater hoses from the vehicle manufacturer. Please go through this guide and let us know how it turns out. I hope this helps.

Hey Alex, I got somewhat of an update for you. I got some pictures to help explain my problem some. I got one replacement part mainly because everybody is out of stock at the moment, but me and my friend from work tried to see if it would snap onto the old clips on the firewall but it wouldn't fit, turns out the clips have a little tab on the sides along with the two teeth that holds the hose on that the new part wasn't made for. So in the pictures I compared the old plastic part of the hose that broke off to the new one I bought. The old one is more circular than the new one, the new one is Carquest brand, I highlighted in red the little tabs that won't allow the new part to go on and in yellow are the teeth that clips the plastic onto the line. The other pictures are of the new part and the lines coming from the firewall, also I removed the old O-rings from the lines because the new part had one in it, I still have them if I need them. So from here do I have to have Motorcraft only or is there a way the old clips come off? My friend said there was something holding the old clips on and even he had a very hard time messing with it. What do you think Alex? Thanks!

Hey Alex,
I wanted to let you know that I finally got it all fixed, I had to climb up on top of the motor just to get to the firewall and I still barely reached it, but I managed to get the old clips off and I simply pushed the new hoses on until they clicked, after that I got another hose coupler and coupled the new hoses into the old ones and it all worked beautifully. Now leaks and great heat, thanks for all your help!
