Radiator cleaners . Any good ?

my cooling system has been slowly leaking coolant (every month i have to add 1 liter of coolant ) .. so for a while ive been using not so good coolant ( coz its cheaper ) since the coolant was leaking anyways ... now im thinking of flushing the system
i ran across this product in the mall ... what do you guys think ? does it really clean the radiator from the possible rust i might have gotten ?

The truth of the matter is if you already have a slight leak on your radiator , flushing it might Be worse for it due to it may result In a bigger leak , unclogging some of the rust that is plugging up some of the unseen holes . Being your profile states that you live in Jordan I would start ordering a new radiator . The cooling system of these cars are the achiles heels of the e34 . In short you need a new radiator .....
Good luck

i didnt say my leak was from the radiator .... im just saying every 3-4 weeks i need to add some coolant ... my guess is that there is a small leakage somewhere in the cooling system ... why am i sure that its not from the radiator ? well, because my old radiator was changed ( not due to leaks , but because my car was euro spec with the smaller radiator .. and in summer it would overheat sometimes )
with the old radiator i had to add coolant every now and then .. and with the new one its the same ..

I guess we're just confused about why you want to flush a radiator when you have a coolant leak from an unknown origin.

Anyway, I would recommend that you find the leak. I don't know about the product you showed. Sorry.

Is your new (current) radiator brass or ali? Ali rads with high phosphate coolant fail very quickly. If yours has only had hi phos coolant then it is possible your car is slowly boiling to cool. No cheap fix. PM me if you want the full explaination. You need a static pressure test on the whole system as well. BTW I've yet to see a pour in cleaner that works. The sad truth is that cheap fixes are temporary at best and can cause damage at worst.

I have never bothered to use them. i believe they are just marketing. i usually just remove the radiator from the vehicle, put the garden hose on full tit and spray down the holes. gets rid of everything eventually.

I used the prestone flush stuff. Took out most, if not all of the rusty stuff that was in the cooling system after years of tap water use.

Does your exhaust smell like burning coolant? It's a sweet smell and very distinguishable. Your exhaust will also be very white. If you don't have a visible leak coming out of your cooling system, your engine may be burning coolant. If that's the case, you may have a larger issue at hand.
