You can also get an IR thermometer at Radio Shack. Not sure what a
laser thermometer is.
If you use mostly water in the cooling system, make sure you add a
rust inhibitor and a lubricant for the water pump. I think Prestone
and others makes such an additive. Not too familiar with this problem
here in Maine.
The problem, as I understand it, with the shroud and the open area
below the radiator in the engine compartment is that, when stationary,
it allows warm air which has passed through the radiator to exit and
be sucked back through the radiator again. Obviously, you want cool
air from outside to pass through the radiator, not warm air. Blocking
the pathway that allows the warm air to recirculate improves the
situation. Once the car starts moving, the circulation problem
disappears, which is why most Tigers with well-functioning cooling
systems do not have a problem at speed.
Tigers are not metric. Be happy they are not Whitworth, either.
