Stant thermostats

Been having trouble with thermostat and it opening correctly and at the right time.
Replaced several times.
Stant used to be a good name brand. After doing some research and talking to the local parts house,...seems they have gone downhill.
On thermostats,.. several recommendations to buy OEM only.
Anyone else with the same problem?
Any other good brands besides OEM?

Sad to say, have heard the same thing. Stant not so good anymore. Find NOS from years ago on that auction site would be good alternative to OEM.

This kind of thing is generally a big problem because it used to be wise to replace trouble prone or trouble causing parts as preventive maintenance. Not anymore, the new stuff is often worse than the old worn out stuff right out of the box. Have slowly accumulated some decent quality parts that will be needed sooner or later that normally I wouldn't keep on hand. Today sourcing parts it's a game of Roulette, bad, worse, who knows, is this a bad dream, etc.

I am curious what you are using the measure the temp and when it opens. Don't tell me you are using the junky factory gauge.

Surely not. My factory gauges are supplied by a true voltage regulator so are as accurate as that style of gauge can ever be. And, I have mechanical aftermarket gauges with a 270 degree sweep, so they are easy to read and quite accurate. I can see when the 'stat opens on the mechanical gauge, but there's no way the factory gauge can react that quickly.

As you know, Jim, the factory gauges are nothing more than a thermometer driven by an electric heating element. The current through the sending unit turns into heat in the heating element and the thermometer registers the effect. That's true of the oil pressure, water temp, and fuel gauge. The result is that they are slow to respond and cannot show quick changes like the 'stat opening. And, if they are supplied by the old ICVR they are highly likely to be wonky.

Errr---Uhhhh
I don't have any problems with my gauges!
Temp may not read out in numbers...but....
Don't remember what degree each letter corresponds with , but....
Checking with my fairly high priced digital thermometer gun
aimed at thermostat housing.... they are constant.
I can see when my thermostat "decides" to open and can simultaneously watch
gauges and gun both reacting at the same time.
Just saying.... no problem trusting mine!
I would not trust them without double checking.......
Then occasionally if you think you have problems, put a tee in....
Check them as many ways as you want.
But I would rather do what it takes to make sure the gauges are right
so I don't have to clutter up the dash or wherever with redundant gauges.....

So what are your findings? What is it actually doing?

I have tried thermostats from AutoZone, Napa, Stant brand, and others in the past few years. None of them worked as good as the Motorcraft ones. Go to the dealer, pay a couple extra $$ and be done with it. Only ones I'll run now.

When I used to sell parts, I would only recommend factory thermostats. I would rather lose a sale and have a happy customer then sell them that crap. Also had customers come back and thank me for that, which gave us business because they trusted my recommendations.

I agree with 81Chop. There are certain parts that should not be replaced with aftermarket. Working at dealers, there were times when we were forced by (customer cost factor) to use aftermarket parts and more than 50% of the time, it did not end well. When it comes to parts like alternators,starters,sensors, stats and such, I would always use and recommend OEM regardless of the manufacturer (Ford,GM,etc.). In my opinion, it costs more in time and hassle to replace aftermarket parts multiple times vs. using the OEM replacement. Kinda like spending $5 in gas to drive to another store because you had a coupon for $1 off of something. You really didn't save anything, you spent $4 more.

Very cool that your gauges are accurate.

It is pretty much the consensus of the forum throughout numerous posts and issues that the factory gauges are not all that exact, hence some responses concerning factory gauges. I chose to run a tri-set of Auto Meter gauges along with a Auto Meter tach and found them more accurate than factory. My truck is far from a restoration, nor will it ever be so I am not so concerned with aesthetics, just accuracy.

Send it to Rocketman and have it converted to a functional voltmeter.
