Hey does any one know if I should change my spark plugs I just turn 60,000 mile mark. The dealer want $480.00 for the seviced check at 60,000 I think that really high any thought's?
I have not seen your spark plugs, but in general Toyota thinks they will last 120,000 miles. (I am using a 2009 Guide, as that is what I own) 60,000 miles or 72 months Replace cabin air filter Replace engine air filter Replace engine oil and filter Rotate tires Inspect the following: __ Automatic transmission fluid __ Ball joints and dust covers __ Brake lines and hoses __ Brake linings/drums and brake pads/discs __ Drive belts __ Drive shaft boots __ Engine valve clearance __ Engine/Inverter coolant __ Exhaust pipes and mountings __ Front differential oil __ Fuel lines and connections, fuel tank band and fuel tank vapor vent system hoses __ Fuel tank cap gasket __ Radiator, condenser and/or intercooler __ Steering gear box __ Steering linkage and boots Additional Maintenance Items for Special Operating Conditions Driving on dirt roads or dusty roads: Tighten nuts and bolts on chassis and body (Even at Dealer prices, I would expect this to cost around $100 unless something they inspected actually needed replacing) 120,000 miles or 144 months Replace cabin air filter Replace engine air filter Replace engine oil and filter Replace spark plugs Rotate tires Inspect the following: __ Automatic transmission fluid __ Ball joints and dust covers __ Brake lines and hoses __ Brake linings/drums and brake pads/discs __ Drive belts __ Drive shaft boots __ Engine valve clearance __ Engine/Inverter coolant __ Exhaust pipes and mountings __ Front differential oil __ Fuel lines and connections, fuel tank band and fuel tank vapor vent system hoses __ Fuel tank cap gasket __ Radiator, condenser and/or intercooler __ Steering gear box __ Steering linkage and boots Additional Maintenance Items for Special Operating Conditions Driving on dirt roads or dusty roads: Tighten nuts and bolts on chassis and body (Even at Dealer prices, I would expect this to cost around $150 unless something they inspected actually needed replacing)
That looks more like the maintenance guide for my FJ Cruiser. There is nothing to grease on a Prius. The cvt fluid is 4 qts and easy enough to diy. The spark plugs should be good to at least 100,000 in a Prius. Once you unbolt and swing that relay box out of the way, very easy to diy. The FJ uses regular spark plugs that need to be changed much more often, but also an easy diy
60,000 is way too early for iridium tipped plugs. $480 is way too high for any level of preventative maintenance! I recently changed out plugs in my '04 RAV4 for the first time, at 150,000 miles. Only one plug looked truly worthy of replacement, though I did not yet have any problem with misfires. Replaced with Denso Iridium IK20 plugs, grand total of $34.44 for four plugs from Amazon.
I changed the spark plugs on my 2006 Prius at 101.7k miles yesterday. It took about 90 minutes. I used NGK IFR5T11 to replace the NGK IFR5A11 's that were in the car. I got the parts at Advanced Auto, where they come up under code 4996 and cost $7 each. According to the manual, the relay box bolt torque spec is 6.1 ft-lbs and the coil bolts are 6.6 ft-lbs. The spark plugs torque to 13 ft-lbs. Good luck!
The only things I would recommend beyond the manufacturer's list above would be to change the transaxle oil, and especially if you DIY, to remove and reinstall the spark plugs with anti-seize. I have 160k on my 08, when I changed the plugs at 120k, they were very difficult to remove, and required much care to avoid stripping the threads. If you are going to use a dealership, make sure you do not buy one of those "packages". Tell them exactly what you want done based on the manual, and get a price quote before the repairs. Good luck with your Prius!
+1 on the anti-sieze recommendation. I originally removed my plugs at ~65K back in 2008, and cleaned them up and applied antiseize, and then put them back in. They were very rough and difficult to remove at 65K. This past Saturday, when I removed them at 101.7K, they came out much more smoothly than they had come out at 65K. This time I replaced the plugs with new ones. I put a little fresh antisieze on the new NGK's ( just a little dab smaller than a pea that I smeared around into the threads).
What help do you need? Post #6 provides tightening torque and one suggested source for the correct replacement iridium spark plugs. The normal replacement interval is at 120K miles. The overall process is to remove the relay box mounted to the cowl, to improve your access to the spark igniters. Then disconnect the wiring harness connectors attached to the spark igniters, and then remove the igniters. Inspect the igniters, looking at the terminals for corrosion and the plastic body for any cracking or burn marks. If you see any problem, replace the igniter. Remove the old spark plugs and examine them, looking at the porcelain insulator at the tip to see what combustion deposits have formed. A very thin layer of deposits is normal. Then while observing the tightening torques listed in post #6, install the new spark plugs, replace the igniters, reconnect the wiring harness connectors (making sure that each one is locked in place, you can hear a little click as the connector engages) and then replace the relay box. Then make the Prius READY and take for a short test drive. Good luck.
Every time I see this subject line the first thing I think is... wow, 2008 plugs would be enough plugs to do complete changes to 502 Priuses. Is that just me or do others out there see this? Or maybe you will now?
going to tackle the plugs next on my 2008 w/ 600,000 km! Helpful post - thanks a lot. Yesterday it was quirkin out red triangle loss of power, today was all good, even got some green bars... Only other concern is the big jerk that happens when the ICE kicks on..
Look up on utube and you will find how to do the change of plugs it is easy peazy. Don't forget the anti seize on the threads and as a added bit of advice put it on the wheel studs as well the next time you remove a wheel.
