ZR-1 Coolant Hoses

[Anonymous]

I needed to replace my oil cooler hoses on my 90 ZR-1 and decided to go to the local ( and only) Chevy dealer here in Sioux Falls because I don't have the tools for this. I decided since I washaving that done to also have the coolant hoses replaced too that I bought from Mid America(their breakdown kit). The mechanic at the dealership told me that the big hoses down below are a killer to replace and that he may have to remove the tensioner pulley to get at things. He also mentioned that the old hoses were glued on(which I think is true since I replace one of the top hoses a year ago and basically had to cut it off). They told me that I am looking at about 6 hours of labor just for the coolant hose. It does look like a killer to get at the lower big hoses but I was thinking 6 hours for me to do it but not the dealer. Does this amount of labor make sense? I am kind of stuck since I am away from my tools but would like a second opinion.
