Sounds like you know the problem...the lines leading from block to heater core, possibly the core itself (smell in compartment). Try to visually find the leak point before jumping in. Check the mechanically or electrically operated heater valve on line into core if so equiped, I have seen these go bad on many diffferent vehicles...

Why would I see coolant leaking from a motor mount bolt

Probably the coolant is leaking from somewhere higher on the engine than the motor mount, and it is running to the lowest point before dripping off. It could be a leak from the head gasket area, or possibly from the front of the engine and the cooling fan is blowing it back. Another possibility is that one of the core plugs (or freeze plugs) is leaking and must be replaced. The worst possibility is that the engine block is cracked.
With the engine off, get under the vehicle with a strong light and check the area above the motor mount closely. If the coolant has been leaking for a while, you should see a nice clean path where it has been running down, possibly with whitish lines along the edge. Trace it back to where it comes from, and you will know what has to be repaired to stop it.

Our 2004 Isuzu Rodeo has developed a coolant leak. The leak appears to be around or above a little panel or plate immediately behind the oil pan? Cannot find any other source. What is inside the littl

You will have to clarify behind the oil pan. Front of engine towards fan. Rear of engine transmission side. Or above the pan towards engine side. If there is coolant leaking from behind the engine (between the engine and trans) and is not running down from above eg head gasket or hose connection, chances are good that there is a frost plug leaking on the rear of the block.

Spewing coolant

You could have a pin hole in your hose or in your radiator.

Yes it would overheat without circulation, but the coolant doesn't circulate through the overflow tank. That reservoir only gets coolant into it when the coolant gets hot and expands and pushes the radiator cap seal up to let coolant into the reservoir. When the vehicle cools down, the coolant contracts and the lower level in the radiator will siphon the coolant out of the reservoir back into the radiator. Coolant circulation is from the engine to the radiator and back into the engine...and also through the heater core.
You may have an air block in the heater core. Check by taking off the outlet hose at the firewall or at the engine and see if you have a slow steady stream of coolant, with the engine running and heater controls on high heat. If it was an air block, a steady stream should quickly start. If you get little or no flow, the core may be plugged and need flushing backward or replaced.

2oo2 blazer overheating. blowing much steam out the top of engine . pouring water out of the bottom .

Well, i would have to say all of the above is a direct result of the water pouring out of the bottom. your coolant system must be full to function correctly, by the cylinders heating the coolant to keep them cool, and then the coolant is cooled back down in the radiator. you can damage the cylinders and more if you run it like that. look for exactly where the water comes out when you pour it in (try to contain any coolant. water alone would be fine to let run on the ground) my hunch is that you probably had a freeze plug come loose from the block, or blew a heater or radiator line. a freeze plug is the little 2" metal circle plate (or even block heater) pressed into the side of the engine under the exhaust on both sides. another possibility could be the water pump. this would be coming from the front side of the engine. there are also many other leak sources, but these are the most common. check the oil. if it is creamy, then there is coolant going into the engine. a freeze plug is an easy fix, as they sell rubber expansion plugs to plug the hole. you sinply stick it in and tighten the nut/screw as per directions and done. a blown hose is relatively simple to fix, but can also be complicated, depending where. most of the heater connections have o-ring and plastic clips that tend to be difficult at times to dis-assemble. a water pump would be expected to fail anywhere between 100k-150k miles typically, and is a cheap repair (i would expect 2-300 in my area)

What is new with the 2008 Malibu cooling system, how do you drain and fill the coolant?

Your Malibu is too new to change the coolant already The coolant is good for 5 years or 150.000 miles, which ever comes first. If oyu are going to replace the coolant, make sure it's the orange coolant and premixed 50/50 water/coolant before refilling the radiator.

To drain the coolant, just disconnect the lower radiator hose. most radiators now don't have a drain plug like the old days. The issue was that the drain plug was breaking since it's plastic or the O rings would break causing fluid to leak from the radiator.

once the radiator is drained, simple reattached the lower radiator hose and refill the system. The other way would be to run the engine till the thermostat opens up and the rest of the coolant in the engine block will make it's way out, but at most you should be fine on to replacing the coolant at the radiator only and then run the engine to ensure you have got all the air out of the system.

Just make sure you replace the radiator cap first before you shut the engine down. It you do shut the engine down first before you place the cap back on, the coolant will blow out.

Thank you for using fixy and be safe.

Loosing coolant leaking from back of engine

Could be a freeze plug or intake or just a pin hole in a heater hose or heater core and leaking down the fire wall down on to the block. Just some of the many places coolant could come from on the back side of a engine. All I can help you with is the Info you have gave us. If you can get us a year make, model and engine size we can help more if you need it. thank you

My 2001 ford taurus is leaking coolant on the firewall side of the engine. is there a coolant hose on that side that could be leaking?

It could be a hose on top of the engine leaking back there. It could also be a freeze plug on the back of the engine. Its a round disk about 2-3" in diameter and is recessed about 3/8" into the block. Check those out and make sure all hoses are good and tight. Any hoses that are kind of puffed out above the clamp should be replaced
