Are you using a sleeved thermostat? =46rom Moss Motors: The Triumph =
thermostat housing has a by-pass which is open when the thermostat is =
closed. The water come out of the head, into the housing, and then =
direct back to pump. This design keeps the water circulating, which =
prevents hot spots from forming in the cylinder head. It also helps the =
engine warm up more quickly. Original thermostats had a sleeve that =
moved to block off this by-pass as the thermostat opens. With the =
by-pass blocked off, virtually all the water in the block goes through =
the radiator. If you don=92t block off the bypass, some water will not =
go through the radiator, and the engine may run hotter as a result. The =
original sleeved type thermostat is therefore more effective than the =
general replacement type thermostat, because it prevents the coolant =
from bypassing the radiator. It also costs more.
I know some who recommend blocking the bypass but this creates hot spots =
in your engine as it warms up as all the coolant goes through the =
radiator. My TR3 overheated for years until I installed the sleeved =
thermostat. Now no problem.
