[TR] 1972 Triumph TR6 spark plug question

[Bud Rolofson]

Try this test.

With a cold engine.  Start the car, turn the heater valve on full  
blast and CAREFULLY feel the upper hose and compare its temp to the  
temp of the heater hoses as the car warms up.  At some point the  
heater hoses should be hotter than the upper hose e.g. right before  
the thermostat is about to open.  If there is no temp differences of  
the hoses after the car has run awhile then the thermostat is probably  
stuck open.  Once the car has warmed up completely the hoses should be  
about equal temp and HOT so watch it.
