ALUMINUM RADIATOR? 1992 Buick Roadmaster 350 TBI
My radiator leaks where the outlet tank meets the core.
Stop-leak is holding it while I look for a replacement.
An exact replacement; brass/copper, 3-row, with trans
fluid cooler/temp sender port/engine oil cooler is $280.
Parts dealers want to sell me a different radiator for $170.
It has plastic tanks and an aluminum-fin core. It looks
flimsy to me; the core is only a little over 1-inch thick,
the fins collapse if you touch them and the core looks
like it is attached to the tanks by crimping and gluing.
Does anyone have an opinion about the sturdiness of
plastic/aluminum radiators or any experience with the
ability of the plastic tanks to withstand heat, cold,
vibration, automotive chemicals, installation stresses,
and hose/fitting attachment torque?
All opinions are welcome.
