    one copper radiator=1000 dollars but will out last your car and will sell for scrap metal ---10 plastic radiator cost 2000 dollars but no scrap value [ all value are a estimated ]

    I thought he was banging his head on the keyboard........


    Ethylene glycol boiling point vs. concentration in water Weight Percent EG (%) Boiling Point (deg F)
    0 212
    10 215
    20 215
    30 220
    40 220
    50 225
    60 230
    70 240
    80 255
    90 285
    100 387

    Why not use 100% ethylene glycol solution and save some money...

    how do we account for the temperature range between 90 and 100 %

    Water has a higher specific heat...the ethylene is there for a couple reasons: lower freezing point and corrosion protection.

    Me thinks the '3' is supposed to be a '2'.

    Well, in all fairness...the BMW one I have is mostly aluminum but it has plastic on the sides and this is where the molded in connection point for the hoses exists. Further, this connection point is the #1 spot for failure.

    About how many miles between replacement, John? I'm at 97k so we'll call mine 100k for replacement #1.

    The first one died at 87000. Then I drove it cross country and it developped a slow leak throw death valley. That was at about 100000. Mine were developping leaks where the plastic joined the metal. I think it's just flexing because of the different CTEs. With less extreme temperatures, it seems to be OK.

    Are you talking about the end-caps? They do fail -- especially if they overheat.

    Sometimes the gaskets also go.

    One of the biggest problems is the upper hose connection on the end-caps. The plastic gets brittle and with the pressure of the hose clamp the connection fails.

    This has been a problem with a lot of makes as the cars age -- failure is often caused when the thermostat fails and the system overheats.

    I'm not sure what this product is going to achieve?

    Just guessing... It might have been developed for race cars or speed boats. Or an industrial use or potential food contact. Looking for a bigger audience.

    I've seen it used a fair amount in street rods with large, high compression engines in small confined spaces with limited space for radiators and airflow. Couple of guys said the best thing they ever tried.
