re: 2000 C70, 2.4
Looking just to be sure, seems changing spark plugs is fairly simple even for me to do.
Engine requires 5 plugs, gapped at .28.
This is the part number, and they usually come pregapped...
FR7DP, 4228
( BTW, I have a tool to check gap...)
Again, thank you!
[No idea about your car, but from years experience gapping plugs...] Gap seems a bit much, or that's a typo. Better double check that...
Sounds about right, it's about what the gap on a 240 is supposed to be. "Modern" cars (as in made in the last 20-30 years or so) with electronic ignition use relatively large gaps compared to the old Kettering ignition systems.
I recommend putting a bit of anti-seize compound on the threads, and be very careful not to crossthread them or over-tighten. They thread directly into aluminum which is much softer than the threads on the spark plugs.
Oops, I mean .028! Yeah typo.
the online maint manual at
Distributor ignition system Firing order: 12453 Distributor ignition setting: Not adjustable Spark plugs: Champion RC8PYP (or equivalent) Spark plug gap: 0.03" (0.75 mm) Tightening torque: 18.4 ft. lbs. +/ 3.7 ft. lbs. (25 Nm +/ 5 Nm)
Replacing spark plugs
The spark plugs should be changed every 30,000 miles (48,000 km). However, city driving or fast highway driving may necessitate changing after 15,000 miles (24,000 km) of driving. When installing new plugs, be sure to fit the right type and use correct torque, see "Specifications". When changing the plugs, check that the suppressor connectors are in good condition. Cracked or damaged connectors should be replaced. When changing the spark plugs, clean the terminals and the rubber seals.
thank you again Reed.. I have saved the links you have given me.. I was unaware Volvo had this all posted...
