I have a 98 Ford mustang v6 3.8 and I was just watching one of your videos about flushing the radiator and I do work on small engines and I can also work on cars a little bit I'm no mechanic but I've been learning a little as I go and mainly watching your videos how I been learning more first question for now is about flushing the radiator I was told that all you really had to do is just flush it and then put some radiator flush cleaner in it and then I saw you have to do with a video I seen you doing I've never seen it done that way which I would rather do it that way that way it would get clean better butI really can't see good witch hoses you swapped around and that's mainly what I'm asking about for now if you could help me out with that I wouldn't truly appreciate it I almost forgot the car has about 165,000 miles on it it's a really good car I bought it two years ago I've done a little work already but I still got to do some more work thanks your biggest fan ..jason
Hey jason hello from california. A radiator can be flushed out from either the top end or the bottom end but preferably the top end if you are working without an electric or hydraulic pump to assist you. Flushing from the top end down would be easiest obviously since you are just working with gravity. I would advise taking a temperature reading of the inlet and outlet hose at normal operating temperature to see that your flush improved some of the heat dissipation. These days the chinese radiators are a dime a dozen and barely cost much to replace. If you have an OEM radiator to begin with you should see about flushing it, but if you are aftermarket to begin with you may save some money and time just swapping the radiator after the temp check.
Basically you flush one way than the other and doesn't matter what you do first you want to flush it and then put the hose in the opposite side of the engine and flush through those houses so it back flushes it do that a few times they'll get all the crud out
