It's a tad high unless he's going to pull it for you. I paid about $70-90 when I carried it in. The clue to a good busy radiator shop is that the owner and all the help are sooty looking, and the shop is a sooty mess all the time. The only shiny thing is the radiators...

I'd pay it if that was the only good local choice. Ask a couple of gen mech shops who they use. I offer to pay for the advice. Usually get it free after I offer, though, and thanked for offering sometimes. Their time IS money...

Ditto the fan clutch. If I was planning on wheeling, I'd probably just go ahead and change it, as it's critical to very low speed high load (i.e., offroad wheeling) cooling.
