Frank: It does have an air pump, with no belt attached and I do not intend to add one.
It does not have any reactors.
How can I make my distributor right?

Benz Dr: 87C is the oem, I have purchased a 75C, but have not installed it yet.
The previous owner had drilled 2 small holes in the thermostat, and to me then it ran too cool and was not running as good as it is now.
