Payed $23 for it at the dealer
Those might be component part numbers then. We need to find a source for them in the aftermarket. I'm on it.

Clarify for me. The fail-safe from the parts store had no valve? Was it MotoRad?

4001-95 is the same as 52028186
4001-80 is the same as 83502426
That 520 number is the same that is on the bag that the tstat came in but has AC after it.

That is correct, or atleast the one I got from the local autozone did not have a valve. Wish I still had the box it came in to get the part number.

It seems they have 3 levels.
Standard
High Flow, which has the valve.
Fail Safe.

I'm thinking we want the HighFlow to match whatever factory is.

Geez,,, I am in the similar realm right now as after first a t-stat /water outlet change and then an entire cooling system replace -Just cause I was in there already and rad was leaking a bit. new w-pump too !

the new Duralast t-stat maybe faulty since I am getting temp readings between 185 to 205 ish (never above though) at crusin.
Prior to all that my temp gauge was rock steady !

So what is the consensus:buy the MotoRad from the dealer or is there another source i.e
O'Reilly etc?
I am seeing alot of reviews saying Motorad FailSafe are crap which I have also heard round here

Think about it......if a vehicle is being operated in very cold temps, and the heater is being used, the heat removed from the cooling system (via the heater core and externally) may be enough for coolant to not quite reach the stat "open temp"....thus the stat remains closed (as it should) and the gauge indicating a slightly lower than familiar reading. Lot's of variables come into play and there are few parts on a vehicle that can be tested as easily as a t-stat.

I would just go with a regular nothing special T-stat
Better to get the one with small hole ?

About to do this change out today...
See post 21. Not ALL MotoRads are Fail-Safe.

We know the ones from the dealer work well. We're trying to find out which one in the aftermarket is available for a reasonable price.

So is it safe to assume that the motorad thermostat (http://www.rockauto.com/catalog/more...698&cc=1180055) is the way to go? Dealer has offered a generous discount to $20+ for their stat, which is ridiculous. My 'stant' stat now fluctuates in temps rather insanely, especially with the cold weather. It gets to operating temp, and then it's like the stat just slams wide open and the temps drop down to the middle hash-mark. Repeat over and over until finally the temps 'stabalize' but still rarely get within 1/8" of the 210 mark.

Also, the listing for the Motorad above says the operating temp is 192* F. Could this be a mistake?

I didn't make it to oreillys this morning to verify anything yet. You could be the guinea pig and get the high flow MotoRad, the one that's NOT Fail-Safe and has the "jiggle valve". Don't worry about the 192*. The stat is a 90*C stat and that converts to 192* F.

That is exactly what my Stant stat is doing right now, super annoying!

The part number listed earlier as a cross over for the Jeep part # but missing the AC is actually a little different:

52028185 <===> 4001-95
Looks like the part # on the Mopar package is 5202 8186 AC. Note the 8186 AC versus 8185 on the MotoRad chart.

Not sure how this plays out in terms of differences, but the part numbers listed on MotoRads website for a Jeep Cherokee is either their "Standard" 200-195 or the "High-Flow" 2000-195.

Hopefully someone has the time to make a trip to the parts store and see if any of the numbers on a MotoRad thermostat are similar to the dealer ones.

I'll be the pig of guinea. Ordering the listed link t-stat now (MotoRad high flow, NOT FAIL SAFE with jiggle valve and junk) from RockAuto. Cost is $10.05 ($3.41 part + $6.64 shipping). When it gets here, do ya'll want numbers and junk off it before I install?

Btw Cruiser, I still owe you a prop valve write-up. I just haven't gotten to it yet.

Yes. You do owe me and the rest of the community!!

$3.41 sounds too cheap for a high-flow.
