Checking engine oil pressure (Renault Espace I)

1. If you have a specially designed connector (Mot. 836) at your disposal, which can be installed together with a pressure gauge, the engine oil pressure can be measured with the engine running.

2. On a 4-cylinder engine, the pressure gauge is installed in one of the four plugs on the side of the cylinder head, and on a V6 engine - in the plug between the oil filter and the front of the engine. In this case, proceed as follows:

3. Warm up the engine to 80°C.

4. Turn off the engine and screw on the connector with the pressure gauge.

5. Start the engine and let it idle. The pressure gauge reading should be within specifications. The engine oil pressure value is not the same for all engines.

6. Increase the speed by the specified value and check whether the engine oil pressure rises to the specified value. Remember that individual engines differ. The values specified are for a new engine. If the engine has been running for a long time, the engine oil pressure value at idle may decrease.

7. Disconnect the pressure gauge and install the appropriate plugs. Very low engine oil pressure indicates possible damage to the oil pump or engine wear.
