Which way does the water go?

[moldman05]

I recently bought a low milelage and original 68 Tempest. It has been sitting for 10 + years. I want to becareful when trying to start to not cause any damage. It has idiot lights so I want to install some manual gauges under the hood. I was thinking about putting a tee in a heater hose for the temperature sending unit and I'm not sure which hose has the water leaving the engine(350). The larger hose 3/4 is connected to water pump housing next to lower radiater hose. Does the water enter the bottom of the radiater and and flow up?

water should be measured by the head or the therostat housing. never herd of an accurate reading in the hose. but maybe theres a secret i dont know

I pretty sure the water enters through the top and exits the btm

Pontiac motors usually have a few npt plugs by the thermostat housing that you can screw the gauge fitting into.

water enters the motor from the lower radiator hose exits through the thermostat

Thanks for the help. I'm going to put a tee in the heater hose leaving the block feeding the heater which should give a pretty close reading. The two ports in the intake manifold are already being used and I didn't want to change or modify anything at this time.

you can also put a sensor in either side of the block, both sides will have a block plug(in line with the freeze plugs) and it's directly in the water jacket.

I did not think about that. I'll crawl under today and take a look, thanks.
