92 delta 88 3.8

hermostat, Replace My database showed this for thermostat removal, if database is wrong, my bad. 1. Remove coolant expansion tank cap. 2. Raise and support vehicle. 3. Open radiator drain petcock and drain engine coolant into a suitable container. 4. Close radiator drain petcock and lower vehicle. 5. Remove upper engine cover. 6. Remove protective shield from under engine. 7. Detach and remove air intake tube from throttle body and air filter housing. 8. Disconnect electrical and vacuum connections from intake manifold and its attached components. 9. Remove fasteners at bottom of intake manifold and at connection to cylinder head. 10. Remove intake manifold. 11. Disconnect hoses from thermostat housing. 12. Disconnect coolant temperature sensor electrical connection. 13. Remove thermostat housing from cylinder head. 14. Remove thermostat and gasket from thermostat housing cover. 15. Reverse procedure to install, noting the following: a. Install new thermostat housing gasket. b. Torque thermostat housing bolts to 88 in. lbs. c. Torque intake manifold bolts to 13 ft. lbs. d. Fill and inspect coolant level.

Your are sure it is transmission fluid? If it is, there are probably seals on the shafts and on the pan that are leaking. This means removing parts like the transmission pan and replacing the gaskets. It could also be a main seal on one of the shafts that are on the engine and output side of the transmission. This is not a job for the average do it yourself person. It requires special tools.

Found this info, it says 88 inch pounds. Hope it helps.

Whistle noise indicates a major vacuum leak. Maybe something loose in the intake system. Maybe a vacuum hose disconnected. Will explain lose of power also.

well, you drop the pan. This job is tricky to have not leak. I suggest that you go to a lube shop, and have them flush the system, then change the filter, in the trans.

Flushing gets the fluid in the torque converter, cooler, lines and the rest of the trans. Nothing is as complete. My fav. is the t-tech machine...What they do is open the cooling line, run the engine and flush new fluid in while allowing old to exit. They do this until clean fluid comes out...

Cool process.

Bonneville, LeSabre, Park Avenue 2000-2005 Intake Manifold - Removal & Installation

3.8L Engine
VIN 1 Engine

1. Before servicing the vehicle, refer to the Precautions section.
2. Relieve the fuel system pressure.
3. Drain the cooling system.
4. Remove or disconnect the following:
   Negative battery cable Supercharger Thermostat housing Exhaust Gas Recirculation (EGR) tube at the intake manifold Engine Control Temperature (ECT) sensor Intake manifold

To install:

1. Install or connect the following:
   Intake manifold with new gaskets. Torque the bolts, working from the center out, to 11 ft. lbs. (15 Nm). ECT sensor connector EGR tube to the intake manifold Thermostat housing Supercharger Negative battery cable
2. Refill and bleed the cooling system.
3. Run the engine and check for leaks and proper engine operation.

VIN K Engine

1. Before servicing the vehicle, refer to the Precautions section.
2. Disconnect the negative battery cable.
3. Drain the cooling system.
4. Relieve the fuel system pressure.
5. Remove or disconnect the following:

Fig. Lower intake manifold torque sequence-3.8L (VIN K) engine

1. Install or connect the following:
   Intake manifold using new manifold gaskets. Torque the bolts in sequence to 11 ft. lbs. (15 Nm); then, re-torque to 11 ft. lbs. (15 Nm). EGR valve outlet pipe Drive belt tensioner assembly. Torque the tensioner bolts to 37 ft. lbs. (50 Nm). Electrical connector to the ECT sensor Thermostat housing Upper intake plenum. Torque the intake plenum bolts to 88 inch. lbs. (10 Nm). Throttle body support bracket Throttle cable bracket to the cylinder head mounting bracket and the cables to the throttle body lever EGR heat shield Fuel rail. Torque the fuel rail bolts to 88 inch. lbs. (10 Nm). Fuel lines Fuel regulator vacuum line Fuel injector electrical connectors Vacuum lines to the intake manifold MAP sensor Spark plug wires Fuel injector sight shield and air inlet duct Negative battery cable
2. Refill and bleed the cooling system.
3. Run the engine and check for leaks and proper engine operation.

Hope this help (remember rated this).

Sounds like a vacumn leak. Gasket under intake plenum may be leaking. Be sure the pcv valve has the o-ring around it in the correct place also as it will set a code.

Check for vacuum leaks.

Air tube between air filter and intake manifold.

If the motor has over 80,000 miles then the intake manifold gasket can **** in air and leaning out the air/fuel mixture.

Give each air / vacuum relayed hose a 1/8-1/4 turn.

Get a steam cleaning on the motor and check for any sign of leak around the sensors.

remove the other bolt from the thermostat housing and remove the housing. My fear at this point would be that by removing intake manifold bolts and wiggling the manifold you may have damaged the intake manifold gasket set, which is a much more indepth repair
