I had a small core std radiator in my car and it was getting hot all the time. in past vehicles (leyland minis) i have tried larger core radiators with the engines i had and they didnt cool as well as this cheapo alloy one.
i even went to the extreme of fitting electric thermo fans to try to keep it cool. dont get me wrong the standard mini radiators are good, i am not putting them down, they do a good job given you have the right one, with the rest of your system working well.
i suppose it comes down to all the other things in your cooling system aswell. i used a new water pump, coolest thermostat i could get, good quality coolant, and i made sure i flushed the block 3 times before i fitted it all back together.
but my cheap alloy rad has been great. i must say the only annoying thing is the coolant discolours the polished tanks easliy. if you spill coolant on the tank when they are hot it marks them with water spots. and you have to polish them out all the time. it can be annoying.
fitment wise, i did have to cut the slightest bit out of the corner of the shroud to fit around the more square edge of the ally rad but otherwise it was a direct fitment in my round nose. i have removed and refitted it a few times now and everytime it is exactly as the origonal was.
im very happy with mine.
Here is my origonal radiator. was recored but just couldnt cool well enough in low speed traffic.
Here is the alloy radiator in all its glory.
Here is another pic of an ally rad i have taken off the net.
I am in the middle of an engine rebuild right now, and will be using the alloy rad again. hope this feedback helps. good luck.
