Heater Core and Low RPM Y-Valve

Recommended Posts

summerfun

My heater started leaking last summer so I put a by-pass hose between the two valves until I could replace it. My friend had just replaced his last year and it cost him about $400 for new heater. I was not in a big hurry to spend that kind of money so I put it off until now. This spring however I found you can replace the core only for under $100, so I thought I would put that out there if anyone else runs into this problem. It was vary easy to replace. The core is only held in the box with a few screws. Take the old one out, slide the new one in. No problem. Check the web sites however, it was a little more expensive directly from Malibu.

I also decided this would be a good time to put in the low rpm Y-valve. As has been noted on this site many times, I plan on putting it BEFORE the impeller. I found it interesteing that when I picked up the valve from the dealer, (he only charged $15, less than I found them online) the dealer instructed me to put in AFTER the impeller and before the trans cooler. I told him that was wrong from everything I had ever read on this board. He said that is how they always put them on. I find in interesting that the dealer does not know how these are supposed to work and I feel bad for the people that pay the dealer to install them and they end up wrong.

Have a good summer. It is the first 80 degree day here, I am heading out.......

My 2 outlet heater started leaking too. HeaterCraft has a 2 year warranty, so they sent me a new core, which is upgraded from the one that came on the boat originally. The new core isn't just the soldered heat exchanger, it's the entire grey box. A new 2 outlet costs about $83 from SkiDim or about $100 from HeaterCraft. The old fan and motor unit bolts back onto that and you connect back up the original hoses and wiring. I did note that the new grey core is a little larger than the original one they were using in 2004, so the re-mounting was just a little more problematic. Edited by Big Mac

$400? Your friend got taken. you can get a new core from Napa for about $35, or one from heatercraft (supposedly different material that will last longer, but I seriously question it) for more money.

Do a search on the site, and you can find the replacement part numbers for the 2 heater core.

The factory was (is?) installing them after the impeller. However, as you say, from everything here is seems as the after installation is not as effective.

I think he did too. The $400 was for a brand new unit plus install from the dealer, so I guess that is about the price for a brand new one. He was never told he could replace the core. When I told him that I was just replacing mine, he was a little upset.

How long ago did it happen? I would go after the dealer....
