1986 Mercedes Benz 300e Water Pump Leaking

Hello George

Sorry Sir - the manual doesn't provide any pics. . .. . .. . ..

If you get the pump say at Auto Zone and do it yourself the pump is about $70 and thermostat about $8. Me - I would check the belt really good too.
WATER PUMP
The water pump and thermostat housing are a single unit which is bolted to the left side of the cylinder block. The water pump is sealed to the block by an "O" ring in the pump mounting base.
Removal & Installation
1. Drain coolant. Remove air cleaner assembly. Disconnect water hoses from radiator. Remove drive belt and power steering pump. Remove water pump drive pulley.
2. Loosen hose clamps on cylinder head-to-water pump cooling line. Remove mounting bolts and water pump. Reverse removal procedures to complete installation.

Now if you have it done, I have put an estimate below. . .. . .. . ...

Hey George - one other thing. . .. . ..

Looks like you may have a recall on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
