: : Jerome,
: : Your problem is a common one but can have more than one solution. First make sure that you have the baffle at the top of the radiator (inside) and that the overflow tube is not too low. If the baffle is not there the water may overflow. Next check the radiator for proper flow.You can remove the upper and lower rubber tubes (block the upper oneby covering it with a plastic bag held with a rubber band) and rand see how much water will flow through the radiator.Use a garden hose and adjust the flow until the radiator stays filled up but there is no overflow.Then without changing the water flow fill up a 5 gallon bucket and time how long it takes to fill.It should take less than 10 seconds. This is a flow rate of 30 gallons per min.If it takes longer your radiator is 'cloged'.If the flow is OK then it could be that your water pump is pumping too much water, this is not likely since it would occure at high speeds and not at idle.

: Another way to approximate if the radiator is resonably OK,is to fill the radiator, with the lower outlet plugged.It should take 4 seconds or less to drain the radiator when the plug (your hand) is removed.

Thanks guys...
I know that there is a baffle because I can see it (when the water is low) and I don't see the fins.I also know that the overflow tube is o.k. because it is just slightly below the cap.I am anxious to get home and try these tests.
