Usually you must remove the top radiator hose where it connects to the engine manifold. The thermostsat should sit in the indentation on the manifold. Very simple, usually just two bolts to uindo.

How do I replace the Thermostat Housing on a 2008 Dodge Magun 2.7L V6?


It will take more than two hours, because the first step is to allow the car to cool for at least 2 hours. But I think that the thermostat should be replaced by the professional repairman, because the thermostat is very important for the car.

2001 A4 thermostat location


Hello! Ignore my request regarding the engine size, The thermostat is well hidden..Standard labor to replace is 2.0 hours...Thermostat is part # 06B-121-111-G....
Step 1: Drain coolant...

Remove bottom belly pan... Remove coolant reservior tank cap... Remove plastic clip holding coolant sensor in place at lower radiator hose/pipe... With bucket/catch pan underneath, remove sensor and let coolant drain...


Step 2: Remove upper radiator hose...

Remove the small hose connecting the coolant reservoir to the upper radiator hose... Then remove the larger hose from the hard pipe running along the intake and from the radiator... You'll need to pop up (but not off) the metal clip holding the hose to the radiator, then firmly pull back..

Step 3: Remove intake hose (throttle body to inter-cooler)...

Remove driver's side headlight (not necessary but makes it a lot easier). Loosen clamp at each end and remove hose...

Step 4: Remove throttle body...

Remove electrical connector and 4 hex bolts (5mm)...

Step 5: Loosen serpentine belt and slip off of alternator...

Use a box-end or adjustable wrench on tensioner, pull to the right... Carefully slip belt off alternator (towards front of car). Allow to hang loose below...

Step 6: Remove alternator bolts...

Remove 4 bolts holding alternator to bracket...

Step 8: Remove vertical support piece from intake manifold to block...

Remove the two bolts holding the support piece (6mm hex)...

Step 9: Remove bolt from metal hose on thermostat; remove bolt from top of oil cooler...

This will allow you to move the hard pipe away from thermostat... Then wiggle it free from the pipe afterwards...

Bolt holding the hard pipe on the right, two bolts holding the thermostat to the block on the left...

Step 10: Remove upper and lower hoses from t-stat. Remove electrical connector on back side...

Step 11: Remove 2 bolts holding thermostat to block, and remove thermostat...See photo below...Guru...Saailer

How to change the thermostat


For 1999 Oldsmobile Aurora 4.0L SFI DOHC 8cyl check thie how to replace a Thermostat:

Parts:
1. Thermostat

Tools:
1. 3/8 in. Drive Ratchet
2. Needle Nose Pliers
3. Screwdriver
4. Cooling System Pressure Tester
5. Socket Set
6. Radiator Hook Tool

Steps:
Step 1 Open the hood and locate the vehicle’s radiator.
o Tip: Make sure the vehicle has cooled down before inspection.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.


Step 2 Remove the vehicle’s radiator cap and use a radiator pressure tester to check for leaks.

Step 3 Drain out some of the engine coolant in the radiator so the coolant level is below the thermostat housing to prevent leaking when replacing the thermostat.

Step 4 If necessary, remove the upper radiator hose.
o Tip: A twisting motion may help to initially break the upper radiator hose loose. You can also use a flathead screwdriver to help pry the hose off. Make sure not to damage the hose.

Step 5 Remove the thermostat housing bolts.

Step 6 Remove the thermostat housing.

Step 7 Remove the thermostat.
o Tip: Make sure to note the way the thermostat is installed. Installing the thermostat backwards will affect how the cooling system performs.

Step 8 Clean the mounting surfaces. Install the new thermostat as it was removed and always use a new thermostat gasket.

Step 9 Reinstall thermostat housing and tighten mounting bolts evenly. If applicable, reconnect the upper radiator hose.

Step 10 Refill the cooling system with coolant.

Step 11 Start the vehicle with the radiator cap off and allow the engine to run for several minutes. This allows the air bubbles to escape the cooling system.

Step 12 Reinstall the radiator cap.

Step 13 Run the engine until up to normal operating temperature. Remember to keep an eye on the temperature gauge to prevent overheating.


Hope helps (remember rated)

Trying to replace thermostat


Reasonably certain that you have to remove the primary drive wheel, which at least on American Saabs is the front passenger-side wheel. The thermostat housing is hiding behind it. You should be able to see it from above, but it's inaccessible except through the wheel well.
Haynes makes an excellent manual with a complete step-by-step walk-through for replacing the thermostat, because I believe it's fairly extensive on this motor.
