sorry but I disagree, just because you have a 180° stat DOES NOT mean your water temp is at 180° constantly.... unfortunately people don't really understand how a thermostat works
if you have a 180° stat, the 180 is the temp at which the stat JUST BEGINS to open up AND it is not fully open until 12-15° above that meaning 192-195° engine temperature...
unfortunately or fortunately depending on how you look at it the cooling surface of our BIG aluminum radiators in a properly functioning and filled system can be too efficient which means you will NEVER ATTAIN proper operating temperatures and this can contribute to poor heat and really CRAPPY fuel mileage in cold weather...
BUT I DIGRESS, you guys do what you want to... personally I will continue to run my 180° stat and run my cardboard in the colder months to reach a peak temp of around 195°... this gives me good fuel mileage and excellent heat to boot..

I purchased a 195 degree thermostat at Napa today. I am hoping that the fairly new old thermostat was defective but I will not be able to do the replacement until after the new year.
Thanks for the suggestions and I will keep you posted!

It seems that it is best to drill a small hole in the diaphragm of your thermostat. 1) it helps bleed the air out of your system (incl heater core = better heat) and prevents vapor lock at the thermostat. I did a 7/64th hole. And remove any metal burs.

In my last truck I had to replace the thermostat every year, no matter how many miles I put on. These were just cheap stant thermostats. It was hit or miss to whether they'd stick open or closed.
Also the hole is a pretty common mod for reasons mentioned above. Many new thermostats even come with a hole in them already.

Interesting to read all these different experiences. I've had a total of 3 stats in nearly 15 years and the current Stant 180 is over five years old with around 70k on it. Never heard someone call Stant "cheap" either. Its always the recommended brand.

need help with heat
I am getting little little heat but nothing to be happy about. A shop said it may be in the heater box under the dash ... I don't know .. blower works don't know if it is the controls because the hot and cold thing feels like it may be broke by turning it

Depending on the year of your truck it could be the blend door issue.
