What could be easier.
That way I also know I can get compatable test strips when I need them.

My engine was completely dry when I installed the last one.
As I remember it took about 7 gallons to fill everything up including the over flow tank.
Napa has the test strips.
You should test the Ph and nitrate levels every three months.

I doubt that your problem is cavitation or a blown head gasket. If it were, you would have water in the oil or leaking from your exhaust. I had the same problem with my 87 on two separate occasions. The first time it was the radiator cap and a leaking hose that only leaked under pressure and when hot. The second time it was the block heater. The heater element had corroded and would leak when the engine warmed up. Figured it out the hard way when it dumped the coolant hauling a load of wood. There is a third cause as well. After a hundred thousand miles, many of these trucks will start leaking fluid from holes worn in the top radiator hose boss. There is spot there on the inside of the radiator that collects grit, corrosion particles and sand grains left from the engine casting. Under flow, the grit acts like grinding compund and eventually wears through the housing. The resultant leak drops the fluid level below the hole and the coolant continues to evaporate through the hole. Unless you notice the wet spot or actually see the coolant spraying from the hole under pressure it's difficult to find. When it leaks, the fluid dribbles down onto the core and evaporates rapidly. the fix is easy, a simple weld or braze that any radiator shop can handle.
