Heat exchanger

[steve_64]

I found an air leak in my heat exchanger. It's the large round one on top that uses the coolant. I'm assuming it isn't a major issue but needs to be fixed.
It's a 2002 WM 1200.

Anyone know a fix for this?

 

[Lee Stockwell]

Air? Coolant? Or plain water?

Do you have 2 side by side?

 

[Lee Stockwell]

Does your engine coolant overflow?

 

[steve_64]

Everything is fine as far as I know except I have a small hole that is blowing air. That exchanger hooks to another that looks like a small muffler that blows out the blower exhaust through the floors

JB weld?

 

[steve_64]

JB weld?

Good idea.
I'm friends with a guy who owns a muffler and break shop. He could probably weld it if it won't hurt anything.
I think the air is just blower exhaust. I just don't want to have to replace it.

 

[Lee Stockwell]

Mine has two identical coolant exchangers, can't imagine needing more heat.

 

[steve_64]

Yeah I'm getting good heat. Just want to be sure I'm not screwing something up.

If water isn't involved I doubt any damage.

Not real familiar with the Vulcan

I'll try and post a pic tomorrow. I don't think it's a Vulcan but really not sure.

 

[steve_64]

I tried taking a pic without removing the cover but it wasn't happening. I cleaned my concrete patio and garage floor with my spinner and cleaned some brick and limestone around my fireplace with my new tile tool in between the rain today.

My friend at the muffler shop said he doesn't have luck welding things like that so maybe JB weld is in the future.

Ok if it's a blower hx the most likely source or cause of a noticeable "air leak" would be trash in the exchanger causing back pressure.

 

[steve_64]

I noticed a rattling noise with it too. I really need a new blower so maybe I'll try and run it till it dies and replace all of it. Might have to call Modernistic and see what it will cost me.

 

[Lee Stockwell]

Maybe you just THINK you need a new blower. If the HX is choking it, it will grumble loudly.

 

[steve_64]

The blower knocks when starting and shutting down. It had been stuck and broke free with a pipe wrench I believe.

I was wondering too if a 59 would fit instead of the 56.

 

[steve_64]

Does anyone know if bluebaron heat exchangers are any good? Talked to them today and they sound good. Just want to make sure I'm getting a good product. I'm still shopping too.

Steve, I have bought a hx from BB. I tried to call and left a couple of messages as I wanted a receipt for tax purposes and he never returned my calls. Not happy with customer service and I'm glad I didn't need something more important.

I'd go with John's custom in Florida... You get what you pay for... Spend a little more and get something that will last..

[Lee Stockwell]

Heard too much bad about BB .

Why do you think you need a new one?

 

[bob vawter]

I alwez cut the ends off....
Applied air pressure...found the leak...
Then silver soldered the pinhole....

 

[bob vawter]

OR.....jus buy that nice new WM one that Tom has....

I filled the radiator and sure enough at least three leaks. I'm replacing it because I don't want to fiddle around with it.

Tom, who's Tom?

Leaking WHERE?

 

[steve_64]

At the connector at the weld above it and a pinhole in the center of it towards the bottom.

 

[steve_64]

I have to take a second look but I thought that muffler in the back was a HX also but now I don't think so.

 

[bob vawter]

OR....you could jus stick MORE bubble gum on it.....
it'll be jus fine!

Probably just let Modernistic take care of it for me.

How do those quick connects work on a HX? Do they have to be replaced often? That is a lot of heat on the seals and it seems as though it would be a weak spot.

This is all new to me. I imagine they are not the same as what's on our tools.
