Now, on to the hardest hose to change in the entire coolant hose system on the 2.3. I saved the best for last.
Here it is. It is up really deep. You cannot see this hose at the top, I had to stick my camera up in there to take the picture. The only way to see it is with a light and a mirror, you can also do it by feel. This hose also has some kind of plastic heat shield on it or something. That is sold separately, but can be reused. Just slide if off the old hose, and slide it on the new hose.
It looks easy from this picture, but it is not. It is really deep in there, and you cannot see it. You have to change this hose "by feel", or with a complicated system of mirrors and lights.
You can see the hose clamp in this picture. The only way to get it is with about a 12 inch long needle nose pliers. You can NOT reach it with a regular needle nose pliers. You also can NOT reach it with a really long needle nose pliers (like 18 inch), because the radiator would then be in the way. I almost was going to pull the radiator and move the condenser forward, because then you could almost lay over the car and stick your head in there and see it to change it. You can also see the oil pressure sending unit and oil filter/cooler housing. You could probably remove that entire housing and go at it from the underside. I also left the first (easy hose) off, and unpluged the oil pressure sending unit connector and moved it out of the way. So I had more room to work with.
Here are some of the tools used for this hose. A mid-sized needle nose plier. A hose plier. An inspection mirror. But mainly I used the mid-size needle nose plier, and did everything by feel. The hose plier should really only be used to remove hoses that you plan on replacing, they shouldn't really be used to install new hoses because you could tear them up. Better to hand install the new hose.
It took a while just to figure out how to go after this hose. The way I found was to be on your knees, with belly against the bumper. Then reach over the radiator, with palm of your hand facing upwards. Then bend your elbow down, and reach in there with your hand with palm up. Then you can feel the clip with your fingers. Then when you can kind of put together a mental image of where the clip is, you can stand back up and use one hand to push the plyer back in there and kind of guide with the other hand. Then when you squeeze the plier, you can feel when you have the clip because of the backforce the clip will push back on the plier. Then make sure you have the clip pressed tight, and then wiggle the clip to back it out.
Here is another view of the clip:
When I twisted it off, the end of the rubber hose snaped off and left a nub of the hose on the connector.
So, I had to get a small flathead screwdriver with a long handle, and use the mirror. I inserted the screwdriver between the rubber hose and the metal connector. Then gently pryed it all around in a circle to crack the seal on the rubber and pop it loose. Then reached in with my hand and twisted it off.
Here is a picture of the metal connector after I popped off the rubber nub left from the hose:
Here is the hose taken off. This was another one that was in bad shape, especially the end of the hose that was clipped to the engine block side.
You can reuse this protector from the old hose. Just remove it and move it over to the new hose.
Here is the final assembly. I didn't use the hose plier to install it, because I didn't want to risk tearing it. So I reached in and pushed it on by hand and feel. It helps to dip the end of the hose in antifreeze, because that acts as a lubricant to help slip it on the metal connector.
