That means that the coolant is boiling. Pressure in the system will raise
the boiling point of the coolant. You should have 7 (or 4lbs) depending on
the radiator cap. You might want to have a mechanic check your cooling system
pressure. Simple job -they just remove the radiator cap and screw on a
pressure guage.

The shroud is important, since it channels any air coming in - even the air
which the fan is pulling into the engine compartment at idle. I also use
"Water Wetter" and have had excellent results from it. Remember that the TR4
radiator is rather small and everything helps. I have considered the over
flow bottle but have just not gotten around to it.
BTW what about your mixture of antifreeze/water for the coolant. More
antifreeze is NOT better. 50/50 (at least 50% water) mix is the start point.
I usually run mine at 70% water - water cools better than antifreeze - but
I live in FL and the since the outside temp rarely goes below freezing I
don't need as much protection against it. Good luck and let us know how it
works out. Cheers
