Engine Diagrams

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

1999 Audi A4 Engine Coolant Thermostat

I completely understand. Here's where you can find the thermostat location:
2.8L V6 Engines

The thermostat is located in the engine block just to the side of the water pump underneath the housing where the upper radiator hose is attached.
  1. Remove the lower engine shield.
  2. Place a large drain pan under the vehicle to collect the coolant.
  3. Remove the radiator cap and drain the cooling system into a suitable container.
  4. Place a large drain pan under the engine block drain located at the bottom of the engine near the vicinity of the flywheel and the oil pan.
  5. Drain the engine block coolant into a suitable container.
  6. Place the (hood) lock carrier in the "service position". For additional information, please refer to the following topic(s): Body And Trim, Service Position, Front Bumper, Hood Lock Carrier.
  7. Remove the accessory drive belt. For additional information, please refer to the following topic(s): General Information And Maintenance, Routing Maintenance And Tune-Up.
  8. If installed, remove the upper front engine cover.
  9. Remove the toothed camshaft drive belt from the right side cylinder head to allow enough access to remove the thermostat housing. Cover and protect the drive belt from residual coolant.
  10. Remove the mounting fasteners; remove the housing, then the thermostat.
WARNING: The thermostat vent valve must be installed facing up otherwise the cooling system may develop air pockets and allow the engine to overheat.
  1. Using new O-ring, install the thermostat making sure the vent valve is installed facing up.
  2. Install the thermostat housing and torque the housing the bolts to 88 inch lbs. (10 Nm).
  3. Inspect the camshaft drive belt for wear and damage and replace if necessary. If contaminated with fluids or lubricants, it should be replaced. For additional information, please refer to the following topic(s): General Information And Maintenance, Routine Maintenance And Tune-Up, Engine And Engine Overhaul, Timing Belt And Sprockets.
  4. Installation is in reverse order of removal noting the following: Top off cooling system with the recommended fluid and concentration. For additional information, please refer to the following topic(s): General Information And Maintenance, Fluids And Lubricants.
Post your email address and I'll send you a couple of exploded diagrams. Have fun.
