B6 Cylinder Head Coolant Pipe Connections The cooling system diagram of the audi a4 1.8t consists of several main components, including the radiator, thermostat, water pump, coolant reservoir, and various hoses and pipes. the primary goal of the cooling system is to regulate the engine’s temperature by transferring heat away from the engine and dissipating it into the surrounding air. So here goes: this is the easiest and less messy way to do a complete coolant system flush (with heater core). drain coolant. 1. jack front end of car up enough to fit a bucket under the car, on the left side of the radiator core. 2. place bucket under the lower radiator hose at the core. 3. The best way to refill your cooling system (without any aids such as a vacuum fill) is to do it with a totally cold system. open the hard pipe bleeder screw and expose the bleeder hole in the upper heater core return line. prop the coolant reservoir up 90° from the normal position. this will increase the static pressure. If you cannot work on a cold car, allow the cooling system to cool down to a coolant temperature of less than 90°c. open the cap of the cooling system slowly; turn a conventional coolant cap as far as the first detent and turn a screwed coolant cap approx. 1 2 turn and release the pressure. wear protective gloves, protective clothing and eye.

Figure 2 the expansion tank is the high point in the coolant system so you only need to drain enough fluid to get below the bottom of the tank. if the coolant in the car is new there is no reason to replace it as long as you drain it into a clean container. note: if reusing the fluid use a container cleaner than the one illustrates in the picture. If you still smell coolant, the other primary leak location on the 1.8 is the coolant flange on the back of the block. peer between the valve cover and the firewall with a flashlight and see if the top of the transmission is "wet". a4 (b6 platform) discussion coolant leak location 2004 1.8t i have a coolant leak, some where right under the.
