    I have been looking for leaks from my original radiator for years. I checked a month ago and no issues but today, I noticed a leak that looks like it's from the top middle of the radiator. I'd like to hears some members experiences with replacing them and any suggestions and tips. Is a replacement plastic FORD radiator OK or should I try to find an aluminum one to replace it with. Cost of OEM vs aftermarket aluminum. How about ease of install for either? What would be recommended after market aluminum and the cost for it vs OEM. I was beginning to think I had the only non leaky OEM one around....LOL! Only have close to 80,000 miles though. Thanks for any info you can provide.

    there is no aluminum Gen 2 rad available...... I use a spectra or other name brand, fords is only made by some one else anyway.....
    As for changing it you need special tools to get the transmission line off and its a royal nightmare !!! I wind up cutting the fitting and using a nut splitter ( don't dare knick the line or it will leak and not seal) to get it off..... ALSO your supposed to drain the AC and take the "unit" out..... I have perfected it so I don't have to do that........ its not a fun project.

    One of my auto teachers back in high school was a Ford master tech for 28 years. He told me a lot of the 4th gen explorers leak from a cracked o ring somewhere in the system. The o ring shrinks small enough when cold to seal, and at operating temp it's expanded enough to seal. But during the warm up progress, it's leaking real slow like, my truck does this and it's why I never see and puddles.

    Darn Todd, you're making me hesitant to even try doing the switch myself. Have to get a special tool and then it's still a PITA? Maybe I should take it to the dealer.

    I was referring to 4th gen explorers, which is the same from the b pillars up as a gen 2 sport Trac.

    the 4.0 leaks from the T stat housing..... the radiator cracks under the overflow bottle, Remove the bottle and there it is !! Or the felt seal from the plastic to aluminum on the rad leak. Crappy design.....

    Sorry for the worry but its a royal pain. Some people were able to unscrew the fitting and just re use that, but not for me, I cut it off and save the time...... Now I don't even take the tool out, its just easier......
