Coolant loss through the water pump bearing seal is commonly caused by a faulty cooling system pressure cap. With certain designs of the plastic pressure cap, if the cooling system overheats distortion of the pressure relief valve in the cap can cause the valve to stick and result in excessive pressure in the cooling system. It is recommended that the coolant pressure cap is always checked for correct operation, prior to the fitment of a new water pump. Thermostat Testing In order to confirm if the thermostat is operating as required, the correct testing procedure should be adopted. Equipment required : 1) A container of undiluted anti-freeze mixture, to allow the temperature of the liquid to be raised above boiling point. (DO NOT use plain water). 2) A suitable heating element to raise the temperature of the liquid. 3) An accurately calibrated thermometer, with a range suitable for the thermostat to be tested. Testing Lower the thermostat into the container of anti-freeze, along with the thermometer, and heat the liquid slowly to the temperature marked on the thermostat, e.g 88 degrees, whilst agitating the thermostat. Let the temperature remain stable for one minute, then check for initial opening of the thermostat valve, Note: The valve will only just crack open at this temperature. Increase the temperature of the liquid to at least 14 degrees above the initial opening temperature, e.g.102 degrees, again allow one minute, then check the valve is fully opened. Allow the liquid to cool to below the initial opening temperature, then check that the valve is fully closed. Opening and fully open temperatures should be within plus or minus 2 degrees of those stated A build up of sediment coating on the thermostat can adversely effect the performance of the thermostat.

Special Precautions Special Precautions Disconnect battery earth lead. DO NOT turn crankshaft or camshaft when timing belt removed. Remove glow plugs to ease turning engine. Turn engine in normal direction of rotation (unless otherwise stated). DO NOT turn engine via camshaft or other sprockets. Observe all tightening torques. Check diesel injection pump timing after belt replacement. Removal Removal 1. Support engine. 2. Remove: Air filter and air intake hoses. Auxiliary drive belts. RH engine mounting. Vacuum pipe bracket. Timing belt upper cover . 3. Turn crankshaft clockwise to TDC on No.1 cylinder. Ensure crankshaft sprocket timing marks aligned . 4. Insert M6 x 1,00 bolt in camshaft sprocket and M8 x 1,25 bolt in injection pump sprocket to lock sprockets in position . NOTE: If locating holes not aligned: Turn crankshaft one turn. 5. Remove: Crankshaft pulley (4 bolts). Timing belt lower cover . 6. Slacken tensioner bolts . Remove tensioner spring . 7. Move tensioner pulley away from belt. Lightly tighten bolts. 8. Remove timing belt. Installation Installation 1. 2. 3. 4. 5. Use crankshaft pulley to check TDC marks aligned . Ensure locking bolts located correctly . Fit timing belt in clockwise direction, starting at crankshaft sprocket. Ensure belt is taut between sprockets. Temporarily fit crankshaft pulley. Ensure timing marks aligned . Fit tensioner spring . Corsa-B/Corsavan/Combo: Slacken tensioner bolts . Allow tensioner to operate. Remove locking bolts . Tighten tensioner bolts to 19 Nm . Turn crankshaft slowly two turns clockwise. Ensure timing marks aligned . 6. Astra-F/Vectra/Cavalier: Slacken tensioner bolts . Temporarily fit crankshaft pulley. Remove locking bolts . Turn crankshaft 60° anti-clockwise (against normal direction of rotation) . Tighten tensioner bolts to 19 Nm . Turn crankshaft slowly two turns + 60° clockwise until timing marks aligned . 7. 8. 9. 10. 11. Ensure timing marks aligned . Ensure locking bolts can be inserted in sprockets . If not: Repeat tensioning procedure. Remove crankshaft pulley. Fit timing belt lower cover . Fit crankshaft pulley. Tighten bolts to 20 Nm. Install components in reverse order of removal.
