I would take the car to another mechanic. With a few tools (pressure tester, mirror or scope, and a good light) that mechanic should be able to narrow the search down to the source. If the heads, intake, and hoses to the heater core are dry. Then it could be coming from a freeze plug behind the trani or maybe from the drain-plug where the heater-core is.
Good-luck.

First-get a new mechanic

Do a cylinder leakdown test
Put in dye designed for the coolant system
Do a pressure test on coolant system
There are other products and tests that can be done.

Antifreeze leak from rear of engine on pontiac grand prix


Rule out leak from water pump. What engine is it - 3.0 3.8. Could be intake manifold gasket. Have the cooling system pressurized, about 12 lbs. and look for leak, bubbles.
check oil for coolant in oil also. Possible head gasket leak.

How to check for leaks of antifreeze/in 97 expedition smell of antifreeze


Hi Sharlene,so you smell antifreeze.Raise your hood and check your antifreeze over flow container,you should have a l and a h mark on it,high and low.If low,then it's leaking somewhere,look at the radiator cap and overflow hose for leak,look at over flow container for leak from hose going to it from radiator,look all over engine,look at top and bottom radiator hoses and clamps for leaks,if leaking there,tighten clamp with flat head screw driver,if no leak is found,get under vehicle and see if any antifreeze is visible,maybe water pump,look on ground for leak and follow,check floor board on driver side,heater core could be bad,check hoses going to heater core from engine firewall.

I will like to know if the antifreeze leak could be from the water pump if the leak comes from the bottom of the car and not from the radiator


ALL antifreeze leaks will be seen coming from the bottom of the car. Yes, it COULD becoming from the water pump. But then again, it could be coming from an intake manifold gasket, a heater hose, a throttle-body heater hose, a freeze plug, a timing cover, a heater control valve, etc..
To find out where it is leaking from, you must follow the antifreeze trail UP from where you see it leaking. Antifreeze leaks ALLWAYS travel downhill. Sometimes they can be deceiving also. I have seen intake manifold leaks at the front of the engine run all the way to the back of the engine and make it look like a rear freeze plug is leaking. Again, you must follow the trail to find the actual source.

I have a 2004 Tahoe and noticed that when operating the heater function this morning, the air was cold. When I drove it for a bit, it started to get warm again. Also, noticed the temp. going over normal...


head gasket leak will act that way when an if it gets bad will smoke white exhaust.will also leak antifreeze into oil so watch oil an frequent oil changes might extend time but will ultimately need new headgasket to avoid damage to engine...think about repairing before damage 2engine.

Just had headgasket done got oil leak carheater not hot bmw 316i


check coolant level,make sure it has antifreeze in ,if ok then quick fix is to put card in front of rad like a blind,watch ice road truckers ,as for oil leak take it back to garage ,also often garages leave the thermostat out in case head was warped or something so engine will not run hot so it last more than a month then its another job?? understand my drift

Antifreeze leaking from the back of the engine. doesnt leak unless car is running on ford 2002 windstar


Sometimes you can rent tools from Autozone or Oreillys and get your money back when you return the tool.
What you want is a radiator pressure checker. With this tool you can pump up the system and the antifreeze will leak out of any hole or hose. You can do it on a cold engine and diagnose the leak safely. It can be something simple like a heater hose clamp or a leaking intake manifold.

check for a wet tailpipe,which might indicate a leak between water jacket & combustion chamber.i.e.headgasket.check heater hose isn't leaking onto exhaust manifold,'cooking' the anti-freeze as it leaks.

Leaking antifreeze fluid from under the engine.


might be a freeze plug leaking, or heater hose. there are three freeze plugs on each side of engine and two in back of engine. most likely if any of them are leaking, it will be the one behind the starter on the far right rear of engine block. they have also been known to leak around the front and rear of intake, where intake, head, and block meet.
