Hello, I was able to replace the heater hose on an 2007 aveo5 special value from the top but I did remove the battery and loosened both the reservoir tank and the wiper motor so I could get the hose off by the engine. I bought the 24" flexible cable/clamp tool on amazon for 13.00 hard part was getting a light in there I ended up with a bare bulb inside plus a headlamp on top of 2 70 watt led lights but that was useless anyway once I loosened the clamp with the pliers (opened and held the clamp) I used a little hook pick to loosen the hose then I grabbed the hose and twisted it off (battery needed to be out of the way)
The other side of this hose was harder actually as very little room to grab the clamps.

I lubed the new hose and I put a deep socket in it to open the ends up for 20 min. I used silicone grease and it slid on. I had to use a z like shaped pick to slide the clamp back onto the heater core nipple. All a pain but found out a damn rat ate the hose.... Now I have to deal with my washer tank to see what's up with that leak again the damn rat sort of like trump LOL
