Thermostat - std vs LN Eng

[clickman]

I just changed out some parts on the car, and thought I'd share a pic of the visual difference between the thermostat that came with the car vs the LN Eng low temp that I replaced it with.

See attached pic.

Interesting that the new LN unit required a push to get it on past the spring.

Great photo... Thanks. This is something I have not done yet, I will add it to the list.

Your engine will be happy once you've made the change

Do you see the car running cooler in the hot weather with the new stat? I've been trying to think through how the new stat combines with the stock fan temp settings. Seems like it would be cooler in steady speed driving but make no difference in traffic but I'd like to hear from somebody who's actually done it.

We have quite a few in service, they all seem to behave the same way. The car runs at a lower steady state coolant temp, but when stuck in traffic, the fans kick in just as they normally would, but when back moving again, the car returns to the lower steady state temp.

A couple of observations to prevent confusion: The dash gauge does read slightly lower, but you need to remember that these dash gauges are both woefully inaccurate and non linear; so you cannot put a lot of faith in them at the best of times. But with the LN stat installed, they do display a lower steady state temp. Secondly, the so-called "A/C hack" to get the dash controls for the air conditioning to display coolant temps is not accurate. I have never seen one that displayed the same values as a PIWIS, Durametric system, or even a lowly OBD II scanner. Differences of 20 degrees or more are not uncommon, so I would not trust the A/C display value at all.

According to the (questionable) gauge, it does run slightly cooler.
