My 1994 has all original hoses and t-stat. The hoses are getting spongy and I don't want to be stuck on the side of the road some night. It looks like this job could be a sob. I consider myself an average mechanic. Has anyone done this job and would you recommend letting a pro do it or should I give it a shot? Any advice/tips would be appreciated and a good source for the parts as well. Thanks, Fife
