follow the water inlet pipe to water pump the thermostat housing connects to water pump this is for 2.4l engine you have to remove exhaust manifold heat shield.you will see the water inlet pipe going to water pump inlet thermostat housing.for the 3.1 engine follow top radiator hose to thermostat housing you have to remove air filter air duct and filter housing , you have to remove throttle body unit with coolant hoses, you have to disconnect accelerator cable, transmission down shift cables at the bracket bolts to throttle body.once you remove throttle body unit then you can see and remove the thermostat housing to replace thermostat.you need to buy new throttle body gasket,and new small coolant hoses connects to the throttle body unit.have extra gallon antifreeze dexcool on hand.
WELL YOU NEED TO DRAIN COOLANT LEVEL BELOW THERMOSTAT LEVEL.YOU HAVE TO DISCONNECT MAF SENSOR LOOSEN AIRDUCT 2 LARGE CLAMPS LOOSEN REMOVE 4 SCREWS TO AIR FILTER COVER LIFT UP REMOVE COVER. THEN REMOVE AIR FILTER AND HOUSING, FIRST DISCONNECT MAF SENSOR.YOU HAVE TO DISCONNECT THROTTLE CABLE AND SHIFT CABLE.YOU HAVE TO DISCONNECT REMOVE THROTTLE BODY COOLANT HOSES DISCONNECT IDLE SPEED CONTROL VALVE CONNECTOR AND DISCONNECT TPS SENSOR CONNECTOR. THEN REMOVE THROTTLE BODY ASSEMBLY. YOU NEED TO BUY NEW THROTTLE BODY COOLANT HOSES AND NEW THROTTLE BODY GASKET FOLLOW TOP COOLANT HOSE TO ENGINE BLOCK.NOW YOU SEE CAN AND REMOVE THE THERMOSTAT HOUSING REPLACE THE THERMOSTAT.BESURE TO HAVE EXTRA COOLANT ON HAND.BLEED COOLANT SYSTEM WHEN DONE.TO BLEED COOLANT SYSTEM REMOVE RADIATOR CAP ON OVERFLOW JUG.THEN OPEN BLEED SCREW ON THE WATER PUMP BYPASS HOSE PIPE JUST A LITTLE.POUR COOLANT IN THE OVERFLOW JUG UNTIL LEVEL STOP DROPPING.STOP AT COLD MARK ON JUG.CLOSE BLEEDER SCREW ON WATER PUMP BYPASS HOSE PIPE.CRANK VECHICLE CHECK FOR LEAKS. START UP ENGINE LET IDLE FEW MINUTES THEN CHECK COOLANT LEVEL ADD MORE UNTIL UNTIL LEVEL STOP DROPPING.PUT RADIATOR CAP BACK ON OVERFLOW RESERVOIR. LET ENGINE IDLE WATCH COOLANT TEMPERATURE GAUGE.WHEN GAUGE START CLIMBING. TURN OFF ENGINE WAIT FEW MINUTES TAKE A LARGE RAG OPEN RADIATOR JUST A LITTLE YOU HEAR HISS NOISE.WHEN PRESSURE STABILIZE DONT GET SCALDED BECAREFUL.OPEN CAP LITTLE MORE.IF COOLANT PRESSURE STILL BOILS OUT WAIT 20 MINUTES ADD MORE COOLANT TO RADIATOR OVER FLOW WHEN COOLANT LEVEL STOP DROPPING.PUT RADIATOR CAP BACK ON START VECHICLE UP LET IDLE UNTIL THERMOSTAT OPEN. THEN FEEL TOP RADIATOR HOSE FEELS HOT THERMOSTAT OPEN WATCH TEMPERATURE GAUGE.IF GAUGE TEMP START CLIMBING TURN OFF ENGINE WAIT A WHILE.CHECK AND ADD MORE COOLANT.WHEN THE ENGINE CAN IDLE TEMP GAUGE STOP CLIMBING YOU HAVE BLEED COOLANT SYSTEM.KEEP CHECK ON COOLANT LEVEL.
How about just get a piece of auto hose at the parts tore and clamp it on there. A lot of rubber parts are not dealer items, just shelf items. There are a bunch of different hoses, some reinforced, oil and gas proof, high temp, rubber, nylon, etc, etc. Just get a good one of the right diameter. Hope this helps.
Under the radiator hose that meets the top of the engine
under the throttlebody if you follow the heater hose from firewall on
the driverside toward the engine it goes to the thermostat housing.
To get to the thermostat you need to remove air cleaner box assembly
from the throttle body and move it out of the way.
Next, remove the nut at the throttle body that holds the steel tube
that goes to the heater hose, remove all hoses that connect to this
tube and raise it out of the way.
Remove the steel line that goes to the radiator surge tank from the
Now the fun part. With a 13MM box end wrench, loosen the lower bolt from
the thermostat housing. A 13 mm socket will remove the top bolt.
Remove the thermostat cover and remove the thermostat.
Reverse to install.
It could be lots of things, one worth checking is to make sure the throttle body is not sooted up excessively. If your mass air flow sensor is not in the throttle body make sure the hose to it is connected and not leaking, Also check to make sure the intake or throttle body are not leaking coolant into the intake manifold. It would be something you should be able to spot with a scanner and a cold start, sometimes dirty mass air flow sensors and even coolant temp sensors can cause it as well. Try cold starting it with the coolant sensor and mass airflow unplugged just to see what it does. This will turn on your check engine lamp however.
FIRST OF ALL YOU HAVE TO DRAIN SOME COOLANT.JUST ENOUGH SO COOLANT WONT FLOW ALL OVER ENGINE.AND COOLANT TO EXPENSIVE ON THE GROUND.TO GET TO THERMOSTAT.YOU HAVE TO DISCONNECT CONNECTORS TO MAF EGR IDLE SPEED CONTROL AND IAT SENSOR.. REMOVE THROTTLE AND SHIFT CABLES FROM BRACKET.REMOVE AIR FILTER ASSEMBLY WITH MASS AIR FLOW SENSOR.REMOVE BOTTOM PORTION OF AIR FILTER HOUSING.REMOVE COOLANT HOSES FROM THROTTLE BODY.THEN REMOVE THROTTLE BODY ASSEMBLY.YOU HAVE TO DISCONNECT SMALL COOLANT HOSE TOP WATER PUMP.REMOVE SMALL BOLT THAT HOLDS METAL COOLANT LINE TO WATER PUMP.THIS LINE HAS TO BE MOVE JUST ENOUGH SO YOU CAN REMOVE THROTTLE BODY.ONCE THROTTLE BODY OUT THE WAY YOU CAN REMOVE THERMOSTAT.BESURE WHEN YOU PUT EVERYTHING BACK TOGETHER.REPLACE THROTTLE GASKET AND THE COOLANT HOSES COME OFF THROTTLE BODY BESURE TO USE OLD COOLANT HOSES MEASUREMENTS FOR NEW HOSES MEASUREMENTS MAKE SURE YOU BUY THE CURVE HOSE FOR THROTTLE BODY. DONT TRY TO USE STRAIGHT HOSE IT WILL KINK AND CAUSE NO COOLANT FLOW.WHEN YOU ARE DONE.FILL COOLANT BACK TO CORRECT LEVEL AND BLEED COOLANT SYSTEM.
Under the wiring harness, which is under the fuel rail, which is under the upper intake manifold. From the front of the car and starting at the throttle body, locate a large rubber hose coming out the bottom of the throttle body, this hose comes straight down, then bends towards the front of the car. A plastic pipe connects to this rubber hose and the plastic pipe continues forward, then bends to the passenger side and dives under the wiring harness a few inches and connects to a 2" long rubber hose which is then connected to the PCV. You can see it actually. Locate the big coolant hose that is just above where the plastic pipe dives under the wiring harness, if you shine a light over the top of this hose and at a fairlt steep angle allowing you to see under the harness, you can make out the PCV.
