So, I pulled my fluidyne rad and what I found was all four corners are leaking, ...and no its not running down from the top to bottom...its all four corner areas and from how it's leaking probably can't be fixed I'm thinking...and even so, why spend money to fix and then install and likely fail again in..what...another 10K miles.. like I said in my earlier post, a waste of time and money.
Of all the posts on aluminum rads I've read over the years and now from experience, there are really none available that don't have some some sort of fitment or quality issue, so I really don't see the point in supporting these types of "upgrades" ...and especially in a stock engine like mine. I'm going back to an oem steel rad and be done with it all.
here are all four leaking corners on this 2 year 5 month, 10K miles fluidyne on a stock engine....and you can see the insulation strips I had to use to fill in the gap around the entire rad.
