Anyone replaced this unit? Is it typical for this part to leak with only 100K on the vehicle?
Anyone have any pointers? It seems like there are two quick-connects that need to be pulled out...and it should come right off. Seems like an easy job.

I did after I replaced my WP/thermostat back in Nov/Dec, the funny thing was the leaks continued with new heat-exchanger until about 2 days and now no leak what-so-ever. Weird indeed.
BTW, I googled the part number and found an online company in Texas who charge around $200 for it (brand new and OEM) with free shipping. The 0-rings come with it. Good luck or you can just drive run the engine until warm in the garage to see if the leak persist (never know, but it may save you a few bucks).
