Sounds like a head gasket. Check for white smoke tailpipe when running.
Passenger side of engine above the compressor.
Just above the coolant thermostat on the passenger side of the engine.
Head gasket, timing cover gasket, or hose leaking.
coolant is leaking above waterpump small black hose going into a PART with two hoses on the other end
On the 3.8L it is above the alternator on the passenger front of the engine.
All fieros have the alternator located low on the passenger side rear corner of the engine V6 engines are almost impossible to service the alternator from above.
Passenger side, front of engine, just above the alternator.
It's behind the alternator; screwed to the block right above the thermostat. Good luck removing it. You need to remove the alternator.
could be leaking from a head gasket and trickling down or your heater core is leaking and driping out of the condensation drain from inside the cab. most likely its your heater core. check the fire wall above the starter and look for that drain line. if it is dripping and is colored (green or orange) its coolant and coming from heater core. that's a bear to replace. good luck.
Right Rear of engine block. Above Alternator, Below coolant drain plug
It is located behind the alternator just above the thermostat. You will need to take the alternator off to be able to reach and change the sensor.
It is on the passenger side of the front head, just above the alternator.
The a/c compressor is located on the top passenger side of your pulley system. It is right above your alternator.
You will need to jack up passenger side and remove passenger front wheel. From above remove belt tension bolt. underneath remove bottom bolt, disconnect wiring. wiggle out from above.
Above the air conditioning compressor on the passenger side of engine and below the alternator.
In a 2003 it's located on the passenger side just above and slightly to the rear of the axle.
The egr position sensor is on the egr valve which is above the alternator on the passenger side of the engine.
In answer to your question the coolant temperature sensor on a 2000 Pontiac grand am with a 3.4L engine, is located on the rear of the engine above the flywheel. It is located just behind the what I believe is the alternator.
Under hood, on passenger side. Above engine coolant tank. Look for metal that says Delphi
The thermostat is located below the alternator on the drivers side. The coolant sensor is right above the thermostat.
look right above the passenger side valve cover, right behind alternator, that is the glow plug relay.
On the V6 it is above the AC compressor and driven by the same belt. On the front of the engine and passenger side. You have to relieve the belt tension and remove the mounting bolts. Also remove wiring. Warning: The alternator has a hot wire. Remove battery ground before working on alternator.
Lots of possibilities. Here's what I can think up in a few minutes. Is the liquid visibly leaking out or just disappearing? Does it come out in bunches or in drips that show up on your garage floor? The radiator could leak through a seam, or due to corrosion in the main core. The heater core could be leaking. Leaking hoses. This could be the main radiator hoses, or the two that go to the heater core. It could also be a leak out of the overflow tank or the line that runs to it. Leaking freeze plugs. These corrode with time, especially if you don't flush and fill your radiator regularly. Is it regularly overheating? Maybe the coolant is just boiling off and escaping through the overflow tank, assuming you have one. Then there's bad stuff. Leaking head gaskets allow the coolant to enter the combustion chamber or the crankcase. And really bad stuff. Your head or block are cracked and the coolant is leaking into one of the places above. SEVERAL THINGS. A HOLE IN A HOSE TO THE RADIATOR FOR ONE a hole in a heater hose or radiator hose a leaking radiator a leaking intake manifold a leaking cylinder head a leaking heater core if there is any coolant on the ground then it should be easy to see the leak. if there is coolant loss and you can not see it, there might be a internal problem (cylinder head gasket) or the coolant is evaporitating before it hits the ground. pull the oil cap off, if it looks like you spit on the cap then its coolant in the oil. you might want to try and run the vehicle and see if you see any blue smoke coming from the exhaust, if so its probaibly a head gasket. i need more information to help you diagnose the problem correctly (year, vehicle, engine size, etc.)
Looking at the car from the front, you will see it near the passenger side wheel well. it is above the a/c compressor and partially obstructed by the intake manifold.
