What services you need and what you don't

[Britprius]

I cannot understand how the Optima at 41 AMP/HR and £173.88 is a better deal than another battery at 60 AMP/HR £65 with 4 year guaranty both being AGM deap cycle batteries.
The other batteries I have listed at £45 if they fail for whatever reason provided they are fitted to the correct vehicle will be replaced free of charge up to 4years. The Optima has only 1 year guaranty.
Lucas now do a battery no price yet but believed to around £80 with a lifetime guaranty. I am not knocking Optima's product just saying that in the UK we have better choices. All the batteries I have listed are marketed by large companies as replacements for the Prius with correct size posts and with vent tube.

This is awesome - thanks! What about

1. oil changes- I have traveled little miles= have a 2008 and it only has 14,4000 miles. How often should the oil be changed?

2. tire rotation - same question.....

3. I now have an issue - the car has been taken into Toyota - I have their five year 'cover all' - haha - - warranty -

it 'appears' as though the 12 volt battery has gone out - got all kinds of squirley messages - any info on this battery - and known issues for this model year?

Thanks so much!

just a list of commonly recommended services, whether they're needed and if so, when, and other useful info.

1. brake flush
may be a good idea after 100k miles/10 years. completely cleaning out the whole system is near impossible with standard brake flush equipment (mainly because the prius has almost 1 gal of brake fluid in it!) possible complications include air in brake system, damage to actuator or solenoid valves. (PS to those of you worried about rusting... the calipers are aluminum body construction with a composite plastic piston.)

2. clean/adjust rear brakes
only if you have drums (obviously in the prius, we do). ideally, for optimal brake life and performance, this is probably a good idea every 30k miles. for other cars, 15k a better idea. when you hear a tone out of the rear brakes, it's either time to change the brakes or have them cleaned/adjusted. if it's not done, you can see an increased brake wear rate (front and rear). possible complications are problems due to technician error- adjustment extremely tight can overheat a bearing. otherwise noise, brake chatter, or increased wear rate and glazing if not properly adjusted.

3. transaxle fluid
there is no way to "flush" the trans on a prius. if someone tries to sell you this, run. they can drain and fill, however. the fluid is expensive and is supposed to go 100k, but you can never go wrong changing it early. in most cases it isn't necessary. this is the same fluid that goes into a tundra for 100k under towing conditions. the only complication you might see is again due to tech error- using the wrong fluid or not filling all the way.

4. engine and inverter fluid
drain/fill is OK, but NO flushes. it's not even possible on the inverter and the engine is difficult but not impossible, however NOT recommended as it can cause serious damage to the electric water pump and switching valves. you do not need the drain/fill until your car hits 100k. if the coolant is still nice and pink, don't do it then either. again, the coolant is said to go 100k. while you're not going to do any wrong by changing it early, again it is expensive like the trans fluid. possible complications include more tech error- bleeding these systems is a PITA and getting all the air out is hard. an incomplete fill, use of the wrong coolant, can damage your car.

5. EFI or fuel injector cleaning
really not necessary until you see 100k, if you have a bad tank of gas, or if you start seeing misfires (and you'll see a check engine light when that happens.) possible problems include damage to fuel lines or connectors while disconnecting/reconnecting the adapter equipment to the system. the fuel line that you would access to hook up the adapter is directly above the exhaust manifold... NOT a place you want a leak. other possible problems could include seal failures due to pressure (rare but possible.) since it doesn't idle, most techs will get in and stomp on the gas pedal until the EFI cleaner runs its course. this leads to a condition called "blinky check engine light" which means that you have overheated your catalyst and are in serious danger of melting the insides of your catalytic converter.

6. three-part service, fuel induction service, throttle plate cleaning
these are all different names for essentially the same service. (the "three part" also includes a top engine cleaner aka fuel induction service and fuel additive.) this is really only needed if the throttle plate starts to stick. a good idea after 100k, but just the throttle plate cleaning. there is no accessible port to feed the top engine cleaner through, and fuel system additives are not recommended with the bladder fuel tank. possible complications from doing various parts of the service: fuel tank additive can possibly damage the fuel system- unlikely but still possible. biggest issue with this is deposits on the spark plugs, causing reduced power and fuel economy. for the throttle plate cleaning, using too much of the cleaner can cause the car to run funny for a few minutes but that's about it.

7. PCV valve replacement
a good idea at a 60k interval just to be on the safe side. if this fails, it will either stick closed (rare) and blow oil seals, or stick open and allow oil to enter the intake. most people forget this valve because it's hidden. but it's a simple replacement and damn hard to screw up.

8. alignment
depends on your driving style. aggressive drivers should have it checked every 10k. otherwise every 15-20k just to make sure it's right. a MUST when replacing tires and if you notice uneven tire wear.

*if you have a question about something that's not listed here, please do ask.

5000 miles or 6 months, which ever is first.

5000 miles, I can't think why months would be important.

A) On any 12 volt battery ever in any car, after 4 years you are on borrowed time.
Because the 12 volt battery does not start the engine in a Prius, Toyota sized it very small, perhaps too small. It is easy to drain it overnight with a dome light. Once completely drained, it never really recovers. A better battery is the Optima Yellowtop, It recovers from draining more than once, but sadly it is not cheaper.

The battery in my RAV just had its 8th birthday. Generally, a flooded Toyota OEM battery (mine came from Japan) is of exceptionally high quality. This leads to complacency with the Prius, and its hopelessly inadequate AGM battery from Panasonic or Yuasa.

FOB?????????

Do ever need to replace the battery (how long) and does it charge when inserted into the dash? If we do what is the battery number?

Thanks,

[Patrick Wong]

Yes, you need to change the 2G fob battery periodically, every two years or so. It is a CR 2032 which you can buy at any drugstore. You will need a very tiny Phillips screwdriver to remove four screws securing a plastic cover over the battery.

No, the fob battery does not charge when inserted into the dash.

Hi,
got a 2008 Prius about a year ago & did not gave service records (its about 150K miles now.. i know its a lot when I bought it but i got a grt deal).. so far, the car is doing fine & i am happy withit. When I took it to the dealer for some service, he recommended a major service..
I plan to do most of it myself..
In the list given by the dealer, he had two items I don't know anything about:
- Install Fuel conditioner - what is this? how to do this?
- Install oil conditioner - same?
I tried searching for the above two - could not find relevant discussions.
thanks,
