I was wondering is it necessary to flush a new radiator and if so what would be the best method of doing so

first water in -> water out

then i'd get some dishwashing soap + water, leave a bit of air and shake it around :)

flush with water, dont forget to test for leaks (fill with air, attach tubing to one end, close off the other with a finger, put it in water, blow in the tubing and see if you get bubbles)

edit: i just noticed you may be talking about a brand-new radiator, in that case i'd skip the dishwashing soap step

I'd do the soap flush either way, there might be residue in there from the production process.

Mainly I use distilled vinegar for flushing.

Now, if I get a used RAD or have one that got cruddy, the solution is to use Prestone Automotive Super Flush. Walmark has it for $2.50 for 22oz.

When I got my 2 rads I cleaned them out with warm distilled water and soap .

In other words yes clean the rad out .
