The previous owner didn't worry too much about leaks. Ive replaced pushrod tube
seals and cover gaskets. nice and dry now.

I have SS exchangers... but the years of leaks have left there mark.
the engine is fairly clean but it's the heat exchangers which are nasty from the
top-end leaks.

Before I put the rest of the ductwork for the heat back on the car I want/need
to clean both the inside and outside of the exchangers. If I don't Im forever going
to be poisoned by the burning remnants of oil. yuck.

without removing them, what is the best way to get them nice and de-greased?
any products work better than other?

thanks!

Simple Grreen seems to work as well as a solvent based degreaser, IMO.

I have good luck using pressure washer concentrate. I use the Pink formula from Generac. I put it in a spray bottle and use it direct. Sometimes too strong. Be careful on Fiberglass and some painted surfaces. I don't let it dry. Really cuts grease and dirt. Solvent cleaners often get grease but not dirt.

Easy Off Oven Degreaser worked amazingly. RESIST the urge to scrape with anything more than a plastic scrub brush. You may need to do a couple of application cycles, but it will work and will not damage the stainless.

HTH,

Couldn't you just take your heat exchangers to a machine shop and have them cooked in the hot tank?

I think to do it right you have to take them off the car, especially if you want to clean the inside too.

Just go to a pressure wand car wash and bring a can of engine degreaser. I couldn't find a shop that would let me put a trans case in the hot tank, so I did that and got great results (IMG:style_emoticons/default/thumb3d.gif)

Easy off oven cleaner worked for me. Several applications, light application of some extra fine steel wool in the tough spots, and finish it off with Mother's metal polish.

what other kind of places would have a hot tank? we have no machine shops local.
(It is central VA (IMG:style_emoticons/default/dry.gif) ). is this another name for a parts washer... or something
totally different?

I was hoping to keep them on, but I agree that getting inside with them on my be
a no-go.

When I had my engine out for sealing and cleaning, I used a dawn product. I think it was called "power degreaser". Comes in a dark blue spray bottle and is kind of a gel type cleaner. Worked outstanding. Did require some re-application and mild scrubbing with a parts cleaner brush. Make sure you wear gloves tho'. Made the aluminum shine like new. Only used cold water to rinse, so if hot water is available it would be even better. Oh, be careful of getting it on paint. It will damage the paint.

By my estimation, this is the 63rd post where Andy has recommended brake cleaner for somthing. If I recall correctly, he even likes it on toast and in his coffee. (IMG:style_emoticons/default/screwy.gif)

Hey... the stuff works well. At the shop I use to wrench at that was the #1 degreaser. It cuts through everything including paint. (IMG:style_emoticons/default/piratenanner.gif) Really don't know of anything better to use without taking it out of the car. Just don't get high off the stuff. It smells nasty.

I use mineral spirits and a wire brush. It’s cheap and washes off with water. I put the mineral spirits in a squirt bottle. Then I rise with Simple Green. I also use a hose connected to the hot water from the sink in the garage. It is amazing how much the hot water makes a difference.

Brake cleaner is great. I use it quite a bit for most everything, but I believe that there are some better products out there (cheaper).

I use Super Agitine in my 30 gal parts washer.

I use Castrol Super Clean in a 5 gal bucket as well. This stuff is real bad for skin and if left in, it will badly damage aluminum, but it takes burnt on oil and grease off better than brake cleaner.

I also use Dawn liquid dish soap in HOT water. That works well on a budget. At $3.00+ a can, brake cleaner can get expensive, so I have found a few alternatives.

I have used the Super Clean and Purple Power in a power washer and they do work well with HOT water (I have both hot and cold water faucets on the outside of my garage.)
