SOURCE: coolant leaking from backside of motor

The cowling for the wiper transmission is in the way for a clear view but take a mirror and try and look at the back of the intake manifold. Very common for them to go bad.

Sound like it is the high pressure power steering line that is leaking, or low pressure line. I would take it to Advance Auto tell them to look at what is leaking they will sell you the part needed. he high pressure line cost more then the low pressure line.

Coolant leak


Most likely cause would be a leaky coolant hose near the engine block. When the car is warmed up and you turn it off, open the hood and look and listen for a hissing or a stream of coolant coming from one of the coolant hoses. If you can't see the source from above, you might need to look from underneath. If you can see where it's leaking, it might be as easy to fix as a hose change. Or it might be something a little harder to fix. But you need to start by finding the source of the leak.

Replace heater core


Instructions
    • Drain the cooling system. Draining the cooling system will prevent toxic engine coolant from leaking into the passenger cabin of the vehicle during removal of the heater core. To drain the cooling system, simply disconnect the lower radiator hose from the radiator by loosening the hose clamp and pulling the hose off. Be sure to drain the fluid into a sealable container and dispose of the coolant at an appropriate disposal site.
    • 2Pull the dashboard six inches rearward. In order to do this, you must remove the following parts; the center dash bolt (located under the defroster vent cover), the bolts under the driver and passenger kick boards, the bolt connecting the dashboard to the radio mount, and the the bolt connecting the dashboard to the rear of the glove box. The locations of these bolts are immediately apparent upon looking under the dash. Once you have removed these bolts, you can pull the dashboard rearward and secure it.
    • 3Remove the heater core box. The heater core box is a black plastic box that surrounds the heater core. This part should be visible when looking down into the dashboard from the passenger side seat. Remove the two bolts on top holding it to the firewall and another on the bottom near the foot well. After removal of these bolts, the heater core and box are attached to the vehicle only by the coolant lines, which you can now disconnect by reaching into the box and pulling them off of the heater core (you may have to loosen the clamps first).
    • 4Install the new heater core. This is accomplished by applying steps 1 through 3 in reverse order; re-connect heater core coolant line, re-install heater core box (be sure to apply silicon sealant to the edges of the box, hermetically sealing it), replace the dashboard and install bolts, and re-fill the cooling system.

Coolant leaking from 1994 Sonoma. Is not near the water pump or radiator, but more towards the back of the block. What might it be?


It could be a heater hose, an intake manifold gasket, or a rusted through freeze plug. You must "look" to see where the leak is originating from.

Water leaks from somewhere under towards the back of the engine and is over heating


There is a hose from the back of engine connecting coolant to heater core. Most of the time it leaks over there. If the hose is not crack, replace the clamp. If it is cracked, replace it. The engine is overheating since it is losing coolant. If you fix the leak, there will be no overheat. Why it leaks there, it is probably from coolant built up pressure too much it has to find the way out. Why the pressure is built up so much, because the thermostat is bad didn't open for coolant cycling through the engine. Therefore you need to replace the thermostat afterward. Cheers.

Anti-freeze leak


If it's leaking at the top of the engine down. Look at the top of the engine at the front and you'll see a bleeder valve on top a black housing. These housings like to come apart at the glued seams. If it's leaking at the lower part of the engine towards the front, it could be your water pump leaking. Check your oil and if you see the color of the oil looking like chocolate milk, your water pump needs replaced, the oil will need changing as well. Do a coolant system pressure test and see if your hoses somewhere are leaking. Also check for your surge tank leaking. This is the tank that you put coolant into.
