That is one of the most disgusting radiators I have seen in a long time
Don't pressure wash it, as it will bend all the fins flat, and you will definitely be looking at a re-core. If it isn't leaking, vacuum, then simple green, soak for as long as you are patient, then wash out with a hose from the back side forward. Use compressed air from the back side as well, but not too close as that can also bend the fins. Repeat and it should clean nicely. Or just give it to a pro and say "Fix".If the original radiator was able to cool the motor even in it's present condition, a refreshed one the same size should be more than adequate. Have the radiator pressure washed and pressure tested. If it leaks have it recored. There is no great advantage to aluminum except cost. As mentioned, changing to anything other than original presents fittiment challenges. Look at it this way, the copper one lasted how long? This should be a wake-up call to anyone having cooling system issues. Because the intake grill for the "cooling package" is so low you suck up everything.
I switched back (from 40% larger aftermarket aluminum) to a boiled/rodded out factory original brass/copper radiator. My average temperature did go up noticeably.[snip] every single radiator shop I talked to said "re-core". The Esprit radiator is a bit odd-sized and there are only a few places which can make the core.
Mine has been in the car for about three years and in hot Florida weather the car never runs hotter than about 82 or so degrees.
^^^ That's what I did in 2005. They boiled and pressure tested it. Sealed off one leaky tube and pronounced it Fit for Service.just give it to a pro and say "Fix".
YOU WIN YOU WIN!
At first, I thought I had found the toupee I lost. :nanner: But, NOOOO. :sad:Is that an animal stuck to it??? :crazyeyes
That entire front undertray was already destroyed on my car from a previous owner (dont know what was up with him, the rear undertray was missing) so I cut the portion under the radiator for removal, im gonna fabricate a new front under tray from aluminum to fill the portion I cut off and make it easily removable for cleaning and maintenance. The mounting portion for the radiator is intact, just the underneath part near the radiator was broken/mangled up. Its now trash. Im guessing it was a lazy attempt and looking at the radiator in the car's past.
