In this article, we have included the 10 Steps for a Maruti Suzuki Engine compression check procedure and compression value PSI for all the Maruti Suzuki makes and models.
Compression Check Tools Required:
- Compression gauge
- Compression gauge hose
- Compression gauge attachment
Compression Check Procedure
Compression pressure check procedure for 4-cylinder or 3-cylinder petrol and diesel Maruti Suzuki engines.
Start the engine and let the engine reach its normal operating temperature.
Once the engine reaches its normal operating temperature, stop the engine. Put the transmission in neutral position, apply the parking brake, and for additional safety, block the drive wheels (so that the vehicle doesn’t roll if you accidentally put the transmission in gear).
Gently disconnect ignition coil couplers (1).
Remove ignition coil assemblies (2) with high-tension cord (3). Mark, label, and take pictures of each ignition coil and cord for reference.
Remove all spark plugs and mark them cylinder-wise for further diagnosis.
Disconnect fuel injector wires (4) at the coupler so that fuel injectors don’t flood the cylinders with fuel during the compression check.
Install the compression gauge (A) into the spark plug hole using the gauge hose (B) and attachment (C). Check the whole setup fitment for eliminating any type of leakage.
In a manual transmission vehicle, disengage the clutch to lighten the starting load on the engine, and in the automatic vehicle, depress the accelerator pedal all the way to make the throttle fully open.
Make sure the battery is fully charged and then start the compression check by cranking the engine and noting the highest pressure on the compression gauge.
Carry out Steps (7) to (9) on each cylinder and note the readings for each cylinder.
Once the compression check is done, install spark plugs and ignition coil assemblies (2) with high-tension cord (3). Connect ignition coil couplers (1) and fuel injector wires (4) at the coupler.
Compression Check Notes:
Petrol Engines: Typically have compression values between 170-200 PSI. Lower values may indicate worn piston rings, valves, or cylinder walls.
Diesel Engines: Have much higher compression values, usually between 350-450 PSI, due to their higher compression ratios.
Testing Method: Compression tests should be performed with the engine at operating temperature, throttle fully open, and all spark plugs removed and fuel injectors disconnected.

Your Ultimate FAQ Guide
What is the recommended compression PSI range for Maruti Suzuki petrol engines?
The recommended compression PSI range for Maruti Suzuki petrol engines is typically between 170-200 PSI, depending on the engine type and condition.
Why do diesel engines in Maruti Suzuki vehicles have higher compression PSI compared to petrol engines?
Diesel engines have higher compression PSI (~350-450 PSI) due to their higher compression ratios, which are necessary for igniting diesel fuel without spark plugs.
What tools are required to perform a compression check on a Maruti Suzuki engine?
You will need a compression gauge, compression gauge hose, and a compression gauge attachment to perform a compression check accurately.
How can I identify if my Maruti Suzuki engine has compression issues based on PSI readings?
If the compression PSI is significantly lower than the recommended range (170-200 PSI for petrol or 350-450 PSI for diesel), it may indicate worn piston rings, damaged valves, or cylinder wall issues.
Does Maruti Suzuki offer hybrid engine options, and what are their compression PSI values?
Yes, Maruti Suzuki offers strong hybrid options like the 1.5L K15C Strong Hybrid and 2.0L Strong Hybrid engines, with a compression PSI of ~180-200 PSI.
Can I perform a compression test on a cold engine, or should it be at operating temperature?
It is recommended to perform a compression test with the engine at operating temperature to get accurate PSI readings.
What is the impact of Dual Jet and Dual VVT technology on Maruti Suzuki engines' compression PSI?
Dual Jet and Dual VVT technology improve combustion efficiency and fuel economy without significantly altering the standard compression PSI range of 170-200 PSI for petrol engines.
Which Maruti Suzuki variants use the 1.0L Boosterjet Turbo Petrol Engine, and what is its compression PSI?
The Maruti Suzuki Fronx uses the 1.0L Boosterjet Turbo Petrol Engine with a compression PSI of ~180-200 PSI.
How often should I perform a compression check on my Maruti Suzuki vehicle?
A compression check is advisable every 30,000 to 50,000 km or if you notice symptoms like power loss, rough idling, or increased oil consumption.
Can I use a compression gauge for both petrol and diesel Maruti Suzuki engines?
Yes, but ensure your compression gauge can measure higher PSI ranges required for diesel engines (up to 450 PSI).
