You explained it really well, I just changed my battery but think it will need alt. Im gonna try to replace it following yr tutorial, thanks heaps. Btw, You have the coolest hair/style. Very nice 👍
Job done ! Thank u mate i just suggest to all that give litle time with engine was running so they can recognise the new alternator.After 15 minutes starts again my heater and my indicators. Happy ending finally.
Car runs bad after restart because the throttle body is dirty. ECU will compensate to make it run correctly but if you clean the throttle body and possibly the MAF sensor it should idle pretty good right after reconnecting the battery. I did the same job and had the same problem but cleaning the throttle body fixed it. Before it had a slight vibration under load with the A/C or a lot of electrical components turned on.
I broke the bolt on mine. A 10 minute job turned into a nightmare. They put low grade bolts in here so be careful and if you get it out without breaking it replace it with Grade 10 bolt for the next guy. The alternator is lile 250 bucks near me so I had to drill and tap mine which was a complete pain in the ass.
No. Belt is screeching because you have to tension the belt correctly. Screeching means it’s to loose. My 2009 yaris sedan did that a few years ago. I loosened the 2 bolts on the alternator and used a pry bar and pulled the alternator more forward a bit. Solved the problem.
2:20 something to note when removing this connector. My 08 is a squeeze release. The video shows the dude easily removing it. What I did was I left it connected and when I was able to remove the alternator. The connector was very easy to remove. I fought it for so long and almost broke it. Don’t do what I did unless absolutely sure.
I think the yaris was running on 500 RPM and dying for a few times not because of the new alternator. Today I've disconnected the battery to clean the connection points and my yaris had exactly the same symptoms as your but then went fine.
It happens because the computer resets the throttle body plate position once the battery is disconnected, when driven for a while the computer adjusts the position again. Or clean the throttle body plate :)
Belt needs to be pulled further up ( towards you if your in front of the car) mine is pulled closer like way further up, that belt is too loose. Has way to much slack, needs to be tighter. You did a good job tho that was the only thing you messed up on. Also, stay oem, Toyota makes amazing cars, and the Yaris is from Japan they’re even better made in Japan compared to Hondas and Toyotas that are made in Mexico, USA, and Canada. Japanese know what they’re doing. When my oem alternator went out a few years ago on my 09 Yaris ( same as yours and also grey) I went to the dealer and spent $280 for a NM new manufactured oem denso alternator. Denso and aisin make amazing parts and are Toyotas lead suppliers. If I got 13 years out of a oem alternator made in Japan might as well spend a little more money and go oem again.
I had a Bosch alternator in before I put the oem one in and the Bosch lasted 2 weeks. Battery light kept flickering. Since I put the denso from Japan In, no problems 2-3 years now trouble free. Make sure to keep that throttle body clean every 10k miles give it a wipe down, keep battery terminals clean too and keep a strong battery in that car AGM batteries are best and maintenance free and last longest. Strong battery works well with an alternator weak battery makes alternator work harder. Also if you replace the spark plugs go to autozone they sell denso TT iridium plugs $40 for 4 plugs. Best plugs out there
Also change that oil every 3k miles or every 6 months whatever comes first I use Castrol 5w-30 synthetic blend oil from autozone amazing oil with a good API rating. These engines are one of Toyotas best engines ever made. Since you drive same car as me I wanna see you get a ton of life out of it bro. If you ever need assistance or have questions on anything let me know I’ve done tons of maintenance to my car I wanna get 5 more years out of this thing so hmu on these comments.
Just did this last night and my new alternator is only putting out 12.3 volts(which I know means it isn't providing any current to the battery). I disconnected the battery before starting. Any ideas what could have went wrong?
That bottom bolt is just stuck hard for me, already kinda slipped and messed the shape of it. No idea how im going to unscrew and replace the alternator 😮
