Boosted Yaris 100k miles service/repair/etc.

[47_MasoN_47]

Hey guys, my 2009 Yaris has just hit 93k miles. Around 50-60k of those miles are supercharged. I change the oil regularly, put new spark plugs in it when I boosted it, replaced the water pump sometime last year (and put all new coolant in). The water pump has been the only "major" repair I've done to the little car. Coming up on 100k though, I'm just curious as to if I should do any preventative parts replacement, etc. or if it's good to keep going until something breaks. I've heard most people say the timing chain never needs to be replaced and that sort of thing, but just want to make sure. It's been a good little car and I hope to get another 100k out of it before I have to buy something else.

That's what I was hoping to hear :)

I put anti seize on my plugs since I plan to leave them in till 100k miles. Deposits on the threads can seize them in place if you don't remove them every so often.

I anti-seized mine when I swapped them out at 50k.

If you use NGK plugs, do not use anti-seize. You could over torque them and break the treads. Very bad. NGK plugs are plated to NOT need anti-seize.

Do you know if a 2005 Camry has these plugs? Unfortunately I waited until 100k to take them out and now they are seized. I'm too scared to force them out if they strip that will be that.

Carbon from combustion builds up on the threads, seizing them. That's different from moisture or corrosion.

It's well known that if you use a torque wrench on lubed threads they ll be overtorqued.

Don't use one and everything will be fine.

spark plugs have built in crush washers. you should remove them as few times as possible.

huh. I always use antiseize on ngk (or any) plugs. it's only bad if you over applicate. (very thin swipe/layer, then roll around sister plug threads to pull even thinner. keep electrode and ground clean) if you install them to "finger tight" then an 1/8-1/4 turn you feel the crush washer crush. I have never had any issues. installed hundreds of plugs over the last 20 years....
