Depending on the year and make of your vehicle, it varies what you can actually replace on a vehicle nowadays. Assuming you have a gasoline engine, 100K is just the halfway mark nowadays; most vehicles easily make it to 200K with little or no major issues. Older vehicles with distributors would benefit from a distributor cap and ignition rotor replacement, igniton wires, spark plugs, PCV valve, Air filter, breather element, valve adjustment and even decarbonization.

The term "tune-up" is often referred to as what can optimize engine performance. A few people often mistake periodic maintenance services such as fluid changes and tire rotation as part of a "tune-up". Maintenance services usually are performed to "prolong" the vehicle's life; preventive if you may.

Newer vehicles no longer have distributors; rather either a coil pack takes care of igniting the air/fuel mix, or each spark plug could have an individual coil (coil-on-plug) sitting on top of it. Coils are not replaced unless they go bad. Spark plugs made with Platinum or Iridium electrodes usually last 100K. Time to replace them. Always use anti-seize compound on the spark plug threads; your cylinder heads are probably made of aluminum and don't want to damage those threads. Those short "boots" that connect the coil to the spark plug is probably in need of replacing at 100K. Rubber deteriorates over time and worn plug boots will result in a misfire. Have a shop perform a "Run-Rite" 3-step fuel system cleaning to remove carbon and varnish left by gasoline. You'll feel the difference when you have clean injectors and intake valves. Emissions are also lowered dramatically. Finally, this may be debatable, but oxygen sensors may certainly be considered as part of a "tune-up".

How about maintenance services due at 100K? If you still have your owner's manual, you'll probably see the following:

Cabin Air filter replacement
Coolant flush
Transmission fluid and filter replacement
Brake fluid replacement
Power steering fluid replacement
Drivetrain gear oil replacement
Lube suspension/steering linkages (if equipped with grease fittings)
Adjust emergency brake cable (unless self-adjusting)
Lubricate hinges, cables. latches, etc.
Rotate tires (unless front and rear tires are position specific), Re-balance if needed.
Oil and filter change
Wheel alignment (if needed)
Shock absorbers (may be replaced as preventive maintenance)
Fuel filter (if serviceable; i.e. not inside fuel tank)

Thanks for choosing FixYa and welcome to the site. At your mileage, it is time to do a tune up anyway. You are going to want to change your serpentine belts. You will want to change your spark plugs/coils, wires, coil packs, distributor cap. You are going to want to change the transmission fluid and filter. Also, flush your radiator and change the coolant. You will want to purchase a new fuel filter and air filter also. It would be a good time for a new PCV valve to. If you want to balance the front end and tires, I would do it. If not, the tune up should increase engine performance. If you have any questions, feel free to ask and thanks for using FixYa.

What should a complete tune-up with new hoses cost for a 2005 Buick La Sabre?

No...your BiL is OOHM (out of his mind) if he thinks they're comparable.

A tune-up shouldn't cost more than $200 - but depends on what all is being done.

What all does his 'tune-up' include? What are the hoses for?

Sell the F150 yourself.... even w/high miles it's worth $$. Go to KBB.COM and look up the Private Party value. Probably $5,000+

I don't know where the plugs are in my towncar. 4.6 2001. I have a miss in the motor . I have not had it tuned up as they say you can go 100.000 . I have 93,000. Or should I take it to the shop?

No where does it say you can go 100,000 miles on any product

Spark Plugs ---get changed at 60,000 miles & not over 3 years
O2 Sensor--- the front ones only-- get changed at 100,000 miles
Trans & Power Steering Fluids --- get changed on ALL Vehicles
every 30,000 miles NEVER over 3 years ( ever )
Brake Fluid --ALL Vehicles every 2 years

No such thing as a tune- up (spark plugs --only)
Computers have done the tuning since 1980 some 32
model years

Plugs are under the COP Ignition Coils
Remove Coils,then Plugs

a vehicle needs to be serviced regularly to keep it in good operational condition, most modern vehicles don't need a tune up as such but should be serviced by a qualified mechanic at the intervals specified by the manufacturer (every 6,000 or 10,000 miles}.....hope this helps......cheers.

You need to change trans fluid on all vehicles every 30,000 miles or two years.
Same on power steering fluid.
Spark plugs every 50 to 60,000 miles or three years
Brake fluid every year,not more than two

There haven't been Tune-ups in 25 years --everything is done with computer/processors

That is called Preventative Maintainance

Looking for a list of parts that need to be changed out on a 2006 ford five hudred for a tune-up

With the advent of platinum tipped spark plugs and distributorless ignition a tune-up doesn't consist of much. Air filters (engine and cabin if equipped) should be replaced at 30k mile intervals (more frequent if in dusty climates). Spark plugs and PCV valve should be replaced at 100k mile intervals. The fuel filter is built inside the tank and is designed to last the life of the vehicle.

So basically if your at 100k miles you should replace the air filters, pcv valve, spark plugs and wires(if equipped). That is the extent of a "tune-up" now a days.

Tune up check list for 59000 miles

Here is the check list. This should also be in your owners manual.

Inspect Brakes and Traction Control
Drive Belt

Fluid - Differential
Inspect front/rear axle fluid level and add fluid as needed. Inspect constant velocity joints and axle seals for leaking. Replace Engine Oil

Change engine oil and filter as indicated by the GM Oil Life System (or every 12 months, whichever occurs first). Reset the indicator. Never drive the vehicle more than 16 000 km (10,000 miles) without and oil and filter change. The system will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5 000 km (3,000 miles) or sooner. Fuel Filter

Oil Filter, Engine

Rotate Tires
