What's the best product to clean the inside of an air-to-oil cooler?

 

Best? I'd say have it ultrasonically cleaned by a professional. We have a parts washer at work Ive used in the past. I put the spigot in the cooler and flush it in both directions. It uses a saftey solvent of some sort.

 

hmm Ok. I wonder if that's expensive. I was more referring to an off the shelf product I can get and use meself

 

3m wax and grease remover would probably work well.

I used gasoline to clean my oil coolern and my intercooler.

worked very well.

 

gasoline rings about right.

Then a match maybe for full cleanliness?

 

i use a cuda!

 

cuda?

 

Use a good concentrated carb cleaner. You'll find it in a gallon can and it'll make aprox 10 gallons. That with some diesel/mineral spirits. After that Try to clean it out good with a good carb cleaner and let it hang to dry. I'd put a lil oil in it and swish it around to see if theres anything in it still. We're lucky they're aluminum, amagine copper or steel... blah.

 

Well I'm using engine degreaser, which seems to work just fine.
