Hello Richard,

There doesn't appear to be a freeze plug on the front of the block.
They are always located on the lower sides of the block.

If you can see water on the front of the engine do a visual inspection when the motor is off and cold.

Take a rag and dry off any noticeable moisture. Start the engine and let it warm up, carefully check all the areas listed below to see if you can isolate the leak.

The radiator could be leaking and dispersing coolant towards the motor while driving the car. A hose or fitting could be leaking. The intake manifold or thermostat gasket could be leaking. The water pump could be leaking at higher RPM's.

Where is the freeze plug location on 1997 chevy 3/4 ton 2500


ther are a number of freeze plugs on that motor , if I remember there are 2 on each side and 2 in the front , pressure test it , you should find your leak then are you sure it is coming from the water pump the water goosneck is right on top of the manifold in the front , those are the only 2 things that can leak unless it is a head gasket on the outside which will not affect anything ,very rare but I have seen it , no hole in the heater hose or bad clamp crack somewhere , pressure test it, you should find it then good luck

check for the leak at the hose housing on the block as they are prone to corrosion under the hose and developing holes. Do the checking while the radiator is under a pressure test then the leak can be easily seen with out the need to have the engine running or be hot.. Check the drain hole under the water pump as the pump seal may be leaking.

My ford has a leak on the right side front it smells like coolant over a two day period all the coolant leaked on the ground what do i do?


Well depending on what engine is in this vehicle, it could possibly be the water pump that is leaking or possibly a "freeze out" plug on the block. I would say it is more than likely the water pump. If you have no noticeable leaks from any of the hoses or radiator, i would definitely suspect the water pump or possibly the thermostat housing may have cracked and started to leak. My suggestion would be to look at all your hoses carefullly and then check the housings where the hoses connect to the engine block, if no signs of coolant are present, check around the water pump for noticeable coolant leaks. Hope this helps in your search for that coolant leak.

Coolant leaking from above front suspension


If it's from the front of the engine, the water pump may have failed. Check for water coming out from the bottom of the pump.
Was the overheating caused by low coolant level?
If not the pump, check your engine freeze plugs and hoses.

Water dripping right front underneath


Is what the liquid plain water or coolant (water mixed with antifreeze). touch and smell the liquid, no smell = water, antifreeze smell and oily feel = coolant.
If plain water, could be Air Condition condensation dripping from condensation drain which is normal. (this drain is usually located near the center of the vehicle).
If coolant, could be leak(s) from: radiator, radiator hose, heater hose, water pump, engine freeze plug. A coolant system pressure test should show what is leaking.

1992 Cadillac still Leaking coolant after water pump change.


Where does the coolant drip from? I had one and only one Cad from this era with the same problem. Turned out to be the recovery bottle cap would let go under operating pressure even though it passed the pressure tester test. Just one of those things.
