Thank you to Bruce Haynes for his 75 Tips for N Series Tractors. This video covers thermostat installation in the upper radiator hose. We discuss the importance of the thermostat and where to get a hotter running thermostat.

The thermostat I installed in my upper hose is one made for a 1977 Renault R12, 1.6L, L4. Here are some part numbers.

A&I A11C15
Gates 33108
Beck/Arnley 1430024
Auto Zone 3518
NAPA THM184

These part numbers are only a guide. YOU are responsible to make sure it fits and operates well.
