'78 CJ5 w/360 Consistent 210* when it's HOT (for Oregon) is this OK

[Turbogus]

Today is the first real speed test, mindful that the ambient air temperature was only 71* going to work (11 miles) and BB made it up to 180* steady. This afternoon's going to get into the 80's so testing will resume. Yesterday at idle I did a full test and low speed seems to come on at AMC 150 * and the mechanical gauge will hold steady at 160*. I shut off the fans at the in cab override switch and let the temp rise to 200* and then cut in the auto switch to the fans, they came on instantly and brought the motor temp down to 160* within 5 minutes. I'm hoping this'll be the end of my cooling issues I've posted about for the last 3 or so years.

Well, here's what $40 clams bought at the wrecking yard, it was already pulled laying in the trunk of a Merc Mystique I could only match by photos from other forums and I'm hoping that I'm not barking up the wrong tree;











The Merc this was laying in had the emission stickers missing as the entire front clip was gone so I'm hoping this is the correct unit. It's the only one available within 50 miles of this consumer desert. What do ya'll think?

i have something similar in my CJ and works real good. And I live in Arizona

Yep, I've seen several posts about this upgrade and I'm a believer. Over the road yielded max temperature of 180* on an 80* day, normal since the upgrade has been around 160*. Missed the real test days last week when the western Oregon temps were in (what we call sweltering) mid 90's.
Today I dialed back the low and high speed fan controls so to keep closer to thermostat temp.

:grinjeep: After a long drive (100 miles +/-) involving highways speeds, upgrades, bumpy dirt and gravel roads at speed. 'Black Betty' never got above 190* and, if I switched to Override she cooled down to 160*! It wasn't the hottest of days (85-87*) but this is precisely when she ran uncontrolled temps of 210* and sometimes higher! In celebration my buddy and I headed up to the Valsetz road to that old swimming hole of my youth and had a hellofa good time coolin' off!
Thanks so much to the kind folks that mentored me here and elsewhere, and a lift of the lynch lid!
