So after climbing Shasta my buddies Jeep started leaking radiator coolant, at 5 pm on a Fri, we still had a 5 hour drive back to SF.
We found this shop in Dunsmir...they were going to close at 6 pm but, stayed open for us,got a new water pump installed that night.Turns out they also climb, so we hung out and had some beers and good conversation.
