oops forgot to update the thread!.
the 180 degree thermostat is a bit hard to find, and getting any 444E thermostat with the right gasket is a bit tricky.. the 180 was technically only offered on the older version of the engine, im using iut succesfully in my late model ..
the Listed Navistar part number for the 180 T-stat is 1845805C1
the Listed Navistar part number for the 190 T-stat is 1845804C1
an aftermarket company by the name of PAI makes a 180. its part number is 481829
PAI also makes a 190 which is 481828
now lets make things complicated because navistar did! I also have a 1845805C2 thermostat which is a 180, it ***SEEMS*** like the 2 are identical.. ?? some how i ended up with both....
I was told by a friend that there are various ones floating around that have different gasket thicknesses but I have gotten no one to tell me which is which.
whats in my bus now? a 1845805C1 with a gasket off a 1845804C1.
some pics for reference.
from left to right.
1. 1845805C1
2. 1845805C2
3. PAI481829
you can see the PAI has the thickest gasket.. (I probably wouldve used this in my bus except it got lost in shipping and I needed to go on a trip.. it came along later so I have never used it but it seems they make replacements for navistar.
running temperatures - with my 180 Tstat in 0f degree weather on the highway the bus will run 175-180. runs cooler in town.. (caveat - I drive around with every heater on maxx and my coat off so I pull lots of heat off the engine in town).
when I had the 190 Tstat in. driving in 0f weather. id run in that 185-190 range on the highway and cooler in town (as expected).
hope this helps??
