Hello again,
What direction through the radiator does the coolant flow? Does the hot water enter at the top or at the bottom? I have searched and found two diagrams telling me different things (see links below)? My car is an '89 if it matters...

Hot water enters the rad. at the top, and cools as it goes down.
Heater flow is from the back of the head to the lower stub pipe on the bulkhead, back out through the upper stub, and into the 'tee' hose.
Treat anything you read on a U.S. car forum with great caution. They don't buy all their (successful) race cars from the UK for nothing.
