If coolant is coming from the bottom of your pump then the bearing and seal are going bad it is time to replace it . you can try flushing your heater core . take the hoses off and using a garden hose flush water through in both directions one at a time .

Coolant level keeps getting very low?

Check the upper intake gasket, you may have a leaking gasket. Check the bottom of water pump and see if it is leaking, if so pump needs replaced. The seal within the water pump sometimes goes bad and leaks out seep hole on water pump bottom. Make these checks with engine off!!! God-Bless!

This is a general idea of how your system works, your heater core is basically a secondary system, your system needs aprox 14lbs of pressure to operate properly, if there is a blockage, your radiator cap is faulty or you are low on coolant you will not get any flow to your heater core thus will not get any heat and could damage your engine, you can get your system tested, and usually if you have a bad water pump you will leak coolant through a small hole in the bottom of the water pump. It is designed to do this so you know it is going bad before you get complete failure however it does not always happen. I hope this helps you

Pressure in the header tank with cool water is a classic sign of head gasket blowing between cylinder and water jacket. Not bad enough to blow water into the oil yet.

You have a coolant leak, the most common - a burst hose, water pump, or leaking intake gasket. If you don't have access to testing equipment, you should have it look at by a repair shop that's equiped.

My truck is overheating and my heater is not blowing out heat

there is a couple of things it can be 1. a leak from a hose, and your low on coolant. 2. the water pump is bad and its leaking out the drain hole in bottom of it, or you have a blowed head gasket. if this is something you just started noticing its most likely one of the first two, if you have been driving it hot for a while, your leaning twards the head gasket..... if you have any questions feel free to ask.

97 chevy 1500 coolant leak

It is the water pump most likely,they have ,what they call a weep hole in the bottom under the pulley,so they will leak out to let you know to change them right away.If it is on the top coming from the intake area,it would be the intake,they are also bad to leak,but look at the pump,under the pulley.

1998 chevy monte carlo leaking coolant

It's a 99% chance of water pump leak or the housing at the timing chain that the water pump sits on.
Water pumps can and do leak one minute then seal themselves.
A cheap fix most use is go to a 7 lb pressure cap on the rad.
