My New POS Thermostat
When I rebuilt the 383 for my '72, I bought a NAPA thermostat. Just recently, my truck started to over heat. Pulled the thermostat and it was stuck shut. Put it in a pan to boil it and it opened once It got to 255*. So being the unintelligent individual that I am, I went back to NAPA, showed it to them and they gave me a free new one. 2 days ago, It starts to over heat. Pull the thermostat and it is stuck shut.
What is a good quality AMERICAN made thermostat that I can buy. I am fed up with chinese/mexican sh!t. |

Re: My New POS Thermos.
Good luck asctually finding one made here. I generally use stant for thermostats and radiator caps and have had any issues that I can remember. You can always hit up the dealer too and get an ac delco part.

Re: My New POS Thermos.
That sucks that you got two bad ones in a row. Did NAPA stand behind them?
I am curious, how did you get the water in your pot to 255 degrees?

To get the water to boil I filled a big kettle type pot with salt water (boils at a higher temp), got the weed burner out and got it to a rolling boil of about 255*(+/- 5*). |

Re: My New POS Thermos.
Most of the other important stuff like Guns and ammo are as well. Most performance parts are still made here too. I think we got all the bases covered lol. Yea its kind of sad manufacturing is all but gone here.

Re: My New POS Thermos.
I was just trying to figure out what the hell a Thermos had to do with an engine.

Re: My New POS Thermos.
Fact about boiling salt water:
"The boiling point of salt water will rise by about half a degree Celsius for every 30 grams of salt dissolved per liter of water." Wow you must have used quite a bit of salt to get to 123.8 degrees C (255 F). Not being confrontational, just sayin... So how much salt DID you use? Inquiring minds want to know. Wouldn't it be easier to preheat an oven to 250 F and throw it in there? That's what I've used for testing temp sensors and such.

Re: My New POS Thermos.
Not as tho it means anything, but the last 2 NAPA thermostats I bought were crap also and one stuck open and never closed, the other would open at 240, drop to 160, back to 220+ and down to 160, back to 220,, not really unusual but it would NEVER stabilize. Up and down, up and down over a 76mile drive in 105 temps with the AC on.
Gave up and ordered a few RobertShaw thermostats from Slummit and ,,, opens at 195-200, drops to 180 and STAYS there. Don't know where there made but they work well (damn well ought to for $25 a piece)

Re: My New POS Thermostat
This is making me think, maybe my temp gauge fluctuating is not wrong, maybe its just the Napa t-stat I put in. Time to pick up the AC delco t-stat

Re: My New POS Thermostat
I just got a new John Deere thermostat for an 830 for my Ford. It is made in USA. I ordered one for a John Deere 4440 for my GMC (smaller diameter) and it is also made in USA. From experience I know that they are good.
