Which spark plug does the Changan CS75 use?
2 Answers
According to multiple sources, the Changan CS75 originally uses LDHDIPVR or single iridium VH7RTCI spark plugs. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the firing order and secure the cover.
I've worked on many Changan CS75 models, and the spark plug specifications depend on the specific year and engine. The 1.5T turbocharged engine commonly uses the NGK ILZKR7B-11S, which is an iridium spark plug with a heat range of 6, offering good durability and ignition efficiency. However, models before 2017 might use Bosch FR7DPP33 instead, so don't assume it's the same across all years. I recommend owners first check their vehicle manual or verify the model number at a 4S shop using the VIN before purchasing. Never buy and replace spark plugs blindly. Spark plugs are crucial—using mismatched ones can cause poor engine ignition, skyrocketing fuel consumption, or even damage the cylinders. They should be inspected and replaced every 30,000 to 50,000 kilometers. Opt for OEM-recommended or equivalent quality iridium spark plugs for longer lifespan and smoother driving. Keep this in mind to save money and drive with peace of mind.
