I do the same when temperature is near triple digits (July/August in the NYC metro area). It certainly keeps it cooler but it SCREAMS like a banshee basically all the time. As soon as the weather cools the 'standard duty' unit goes back in.I'm at ~65k with that Hayden 2634, waterpump is around 90k.
No issues so far. I installed it when I did the waterpump, but Ill swap in an HD Unit occasionally during the summer if we are going to be off-road when its 100°+
If you do, please post the results.I'm somewhat seriously considering an electric fan swap. Anyone have improved performance with their electric fan swap? I did on a 200tdi in a 110 and never regretted it.
i just checked out the flowcooler and the price isnt bad if it works as well as you say.The hayden and flowkooler are working great on one of them. the other one is so gunked up with crap in the block and heatercore that flushing it is about an every other day task
Going to try a real filter on it and see how that goes
i just installed one from Atlantic British and it was a borg warner its a little bit loud at start up but its working better than expected. i have a flowkooler on order but haven't received it yet.There isn't one.
My brother called me yesterday with that very same question.
My ballpark answer is this - buy whatever Atlantic British sells, install it, and have a $30 POS from Amazon as a backup. Or make yourself a part to lock the clutch when it gets hot (two hose clamps will do it).
The proper answer is what Jimmy said. Need to make or find a good electric fan setup.
So what’s the verdict?
13 years ago I had the hayden HD one , and my fan blew up On a cold start one morning.Hayden clutches are junk. They don't have a crisp engagement/disengagement action of a proper LR clutch, and instead drag on forever.
Not sure about the brands of OEM clutches, but I've had good luck with all I ever bought at Atlantic British or LRDirect.
200F is on the high side of my personal preferences, but not at all excessive.iphone said 100F when I started
