Coolant circulation pump "V50" (coolant pump "V36") for vehicles with a 4-cylinder engine

For vehicles with a 4-cylinder engine and additional equipment with a start/stop system, but without additional equipment with an independent heater, a ("V50") "V36". Control "V50" ("V36") depends on the vehicle's configuration and production date. For vehicles with a 4-cylinder engine and optional start/stop system, but without optional independent heater, the coolant circulation pump "V50" ("V36" A) is installed, for example, in the area between the engine and the front wall of the water drainage box.





This is the drawing the location shown is for the Audi A4 with a 4-cylinder TFSI engine, 2010 model year. Depending on the engine, vehicle type, and production time, the coolant circulation pump "V50" (water pump "V36") "A" may also be installed in a different location (for example, in a water drainage box). When working "V50" ("V36") The coolant is sucked in through the coolant hose "B" (from the engine through the climate control heat exchanger. installation and shut-off valve of the coolant "D") and via the coolant hose "C" flows back to the engine (observe the flow direction "arrows"). "V50" ("V36") with the ignition on, depending on the temperature. Coolant and reg. on pan. manager and climate indicators. installations, used Clmatronic "J255" receives direct control signals from them. Depending on the vehicle version "V50" ("V36") receives control signals not only when the stop function is active, but also when the engine is running, for example, when pre-selecting the temp, on Heat on the panel. control and indication, used Climatronic "J255" (HI indication on the panel display. climate control and indication. installations and MMI). The control of the coolant circulation pump "V50" is then carried out to support the engine coolant pump. On vehicles with a start-stop system "V50" ("V36") and the coolant shut-off valve for Climatronic "N422" is controlled directly from the panel. climate control and indication. installations, used Climatronic "J255". If the fault persists. on these nodes in pan. climate control and indication. when installing a used Climatronic "J255", it is necessary to comply with the design, coding, and adaptation of the "J255". On vehicles with an optional independent heater, the coolant shut-off valve for the Climatronic "N422" is not installed "V50" ("V36"). In such vehicles, this function is performed by the components of the independent heater (the coolant shut-off valve for the heater "N279" and the circulation pump "V55").

Coolant circulation pump "V50" (coolant circulation pump "V36") for vehicles with a 6-cylinder gasoline engine

For vehicles with a 6-cylinder FSI engine (the 6-cylinder TFSI engine is not currently available) and on other engines with certain additional equipment (for example, in a car with a start/stop system but without additional equipment, an independent heater is installed "V50" ("V36"). For vehicles with a 6-cyl. FSI engine without an optional independent heater, a "V50" ("V36") "A", for example, in the area of the engine and the right side member under the right headlight.



Coolant circulation pump "V50" ("V36") depending on the production date, it is controlled via the circulation pump relay "J160" (via the same output as the coolant shut-off valve of the Climatronic unit "N422") or directly from the used and climate control indication. installations, used Climatronic "J255", which is gradually installed with mod. year 2009. On a car with a circulation pump relay "J160" (for example, on a 2008 model year car) management is carried out "V50" ("V36") with the ignition on, if the Climatronic coolant shut-off valve "N422" is not controlled correctly (e.g. when the temperature mode is warm on the panel. climate control and indication. installation, Climatronic unit "J255"). On vehicles without the "J160" circulation pump relay (gradual implementation from mod. year 2009) "V50" ("V36") with the ignition on, depending on the temperature. Coolant and settings on the pan. climate control and indication. installations, used Climatronic "J255" receives control signals directly from this panel. Depending on the vehicle version "V50" ("V36") receives control signals not only when the stop function is active (gradual introduction as an additional equipment since 2010 model year), but also when the engine is running, for example, when pre-selecting the temp, on Heat on the panel. control and indication, used Climatronic "J255" (HI indication on the panel display. climate control and indication. installations and MMI). The control of the coolant circulation pump "V50" is then carried out to support the engine coolant pump. On vehicles where the coolant circulation pump "V50" "V36" and the coolant shut-off valve for Climatronic "N422" are controlled directly from the control panel. climate control and indication. installations, used Climatronic "J255", these units still have faults in the panel. climate control and indication. installations, used Climatronic "J255". Therefore, the design, coding, and adaptation of the "J255" must be taken into account. On vehicles with an optional independent heater, the coolant shut-off valve for the Climatronic "N422" is not installed "V50" ("V36"). In such vehicles, this function is performed by the components of the independent heater (the coolant shut-off valve for the heater "N279" and the circulation pump "V55").
