Anyone using aluminum radiator in the C body Chrysler (300/Newport/New Yorker/Imperial)? Looking to replace the stock radiator in my car. Its weeping in places and I believe it may be clogged, I'm overheating on the highway. It is fine around town, but soon as I get up to 50/60/70mph the temp swings up to 230 degrees. I know that's not absolutely terrible (I believe 250 is shut down and quickly pull over temp) but it makes me nervous nonetheless. She's been running around 190-200 until its has started getting warm around these parts again. I've checked all the other variables....defective thermostat, collapsed hoses, blocked passages in the motor itself, ignition timing, even leaned out carb -- everything seems to check out. So since it would have to come out (radiator) for further inspection/cleaning, I might as well put in a brand new piece instead of dick around with the 40 plus year old one...and I've been eye on the aluminum pieces for a while now. If ya have one and can give me the manufacture that would be cool (hahaha), also are you happy with it. Thanks!
