My sincere thanks folks. I actually pulled the engine cover off to see if I would be able to do this as a DIY. The hose connections on the left side are easy to get to, but on the other end, the space looks really tight and I am not sure I'd be able to do this job. So, if anyone can recommend an independent mechanic in the NY / NJ / PA metro area, I would greatly appreciate it. Thanks again.
