Peugeot 308: Checking and adjusting values : EB2LTDH2 engine type

Peugeot 308 2021-2024 (P5) Service Manual / Mechanical :: Engine / Engine assembly / Checking and adjusting values : EB2LTDH2 engine type

1. Foreword

1.1. Units of pressure

1.1.1 - Units of pressure in bars.

N.B. : One bar has the advantage of being close to the average atmospheric pressure at sea level.

1.1.2 - Unit of pressure in millimetres of mercury (symbol: mmHg) or Torr (symbol: Torr).

This unit of measurement of pressure was origially defined as the pressure exerted at 0°C by a 1 millimetre column of mercury, later indexed to the atmospheric pressure.

The pressure values indicated in the tables below are the values read on the pressure gauge (Relative pressure).

N.B. : Relative pressure is equal to absolute pressure minus atmospheric pressure.

1.2. Units of tension

The SEEM unit measures by deflection of the static tension of the belt, by deforming a portion of its length.

4. Oil capacity

Description Value
After oil change, without replacement of filter 3 litres
After oil change, with replacement of filter 3,5 litres
Difference between minimum and maximum on the gauge 1 litre

Oil change interval : Refer to the maintenance schedule.

CAUTION : Always check the oil level using the dipstick.

5. Oil pressure

Oil pressure is checked with the engine hot after checking the oil level.

Oil temperature fixed at 80 °C.

Engine speed Minimum oil pressure
750 rpm 1,6 ± 0,3 bar
1000 rpm 1,9 ± 0,3 bar
1500 rpm 2 ± 0,3 bars
2000 rpm 2,1 ± 0,3 bars
3000 rpm 2,5 ± 0,3 bars
4000 rpm 3,1 ± 0,3 bars
4500 rpm 4,2 ± 0,3 bars

CAUTION : Carry out work on the engine if the oil pressure values are below those in the table.

CAUTION : The values read on the diagnostic tool are indicated in absolute pressure.

6. Ancillary drive belt

operation Adjustment
Belt tension By dynamic roller tensioner

7. Timing chain

operation Chain tension
Chain tension By chain tensioner

8. Coolant pump

operation Adjustment
Belt tension Elastic belt (*)
(*) Replace the coolant pump drive belt (After each time it is removed)

9. Cylinder head bolt

CAUTION : After a removal, systematically replace the cylinder head bolts .

10. Pressure, engine end of compression / Cylinder leakage rates

10.1. Pressure, engine end of compression

Measure the pressure at the end of compression, in order, on cylinders 1, 2 and 3.

Description Minimal value Nominal value
End of compression pressure 9 ± 0,3 bars 12 ± 0,3 bars

N.B. : The difference in pressure between 2 cylinders must not exceed 3 bars.

CAUTION : Always search for the origins of fault(s), where the values measured are found to be significantly out.

10.2. Cylinder leakage rates

Cylinder leakage rates are considered non-compliant if they are higher than the following values.

Measuring of the leak rate of the cylinders

Km (mileage) Less than 30000 kilometres 30000 to 100000 kilometres More than 100000 kilometres
Leakage rate 10% 12% 16%

11. Fuel pressure

Description Pressure
Fuel circuit pressure 5 ± 0,2 bars
