Disconnect and release the plug "2" of the exhaust temperature sensor 4 "G648" on the air duct pipe. Remove the air hose with the air flow meter "G70", to do this, loosen the hose clamp "5" and loosen the clamps "arrows".
Disconnect the electrical connector "arrow". Unscrew the coolant temperature sensor "G62".
Installation
Install in reverse order. Replace the sealing rings. To avoid coolant loss, immediately insert a new coolant temperature sensor "G62" into the threaded hole. Hose nipples, air ducts and hoses must be cleaned of oil and grease before installation. Secure all hose connections with hose clamps of the appropriate series. To ensure reliable fastening of the air duct hoses to the nipples, treat the threaded connections of the already used clamps with a rust remover. Install sensor 1 of the exhaust gas pressure "G450".
