I must admit, this isn't my best shot video. I should have chosen different camera angles so you could better see the bolts, however, this video still gives you a good idea of what you would need to do to replace an alternator on this vehicle.

Watched this video before changing the alt on my brothers. You absolutely shouldn’t remove the motor mount as there is no reason(no offense). The alt fit perfectly underneath the upper rad hose( I personally just opened the rad cap and squeezed the hose, then closed the cap to make it more flexible to move the alt under). But it fits under no problem. As for the tensioner, I personally had to tighten it while it was running to get it perfect, then turn the car off and clamp all 3 bolts. Thanks for the vid

removing the engine mount is optional it's alot easier to remove the coolant res it slipped out for me no prob and i had tons of room to get the bottom bolt out

That is the easiest and proper way, unless one fears spilling some coolant liquid.

samuel lopes I totally agree, When he started talking about removing bracket, I said hose it is, as some antifreeze and that's that

@shadowthahedgehog33 5 жыл бұрын

Samuel lopes so true Mom always taught me work smart not hard and he is working to hard. It's easier to just take the hose off put a little small bucket under it to catch the antifreeze and then take the alternator out and put the new one in put the hose back on and re top with more antifreeze because you won't loose all your antifreeze from that top hose anyways.

I've done this twice, taking the hose is the best move. 1 hour job tops.

You don’t need to remove the hose.

If the coolant went into the alternator would it ruin it

Thanks for the video +50skid! Saved me a bunch of $$ for sure. There was some collateral damage - broke the coolant temperature switch terminal since it is part of the same harness. How tight should the belt be? Is there a torque spec for it or some other method for checking?

@50sKid 7 жыл бұрын

I broke the same switch myself at some point. I usually make the belts tight enough that I can twist them 1/4 around in the middle of the longest span, no more, no less.

@Bonbonbon739 2 жыл бұрын

find the longest part of the belt, and you should only be able to twist it exactly 90 degrees. No less no more

my alternator starts at around 13.8 then slowly starts going down 13.7 , 13.6 etc with the radio and everything off . its a new alternator but I don't think its working the way it should never goes up to 14.5 . do you think I need a new one or any other things I could check ?

@50sKid 7 жыл бұрын

What does your battery read when the car is off? Usually alternators are voltage regulated to be 2 volts higher than the battery, so 12.5 = 14.5. If your battery is 11.8, it may not be bad. Charge your battery up until it's at 12.6 after taking off the surface charge and then recheck the alternator.

@warriors71759 7 жыл бұрын

ya i have done that already and get the same thing and if i load it with everything on it drops below 12v and doesn't go back up that's why i think its the alternator but its new so i don't know if maybe i got a bad one from store and with the battery voltage it will start at 12.5 but starts going down the more and longer the battery is used until the car wont even start because the batterys dead

@50sKid 7 жыл бұрын

Check the alternator connections for corrosion, also check the battery connections for corrosion. Including where the negative cable connects to the engine and frame. If you find corrosion, sand it off with sandpaper until you have bright shiny copper.

@warriors71759 7 жыл бұрын

all the connections are clean and good . also the voltage drops even lower when the cars in drive and iam at a stop until i give gas .

@DeathInANuse 7 жыл бұрын

That sounds like it's just based on the throttle. Check what rpm your engine should be at when running and in park/neutral.

Hey! I really appreciate the video. It just helped me with my first car. I do have a question tho, how tight should I re-tension the belt?

@50sKid 6 жыл бұрын

It's kind of a feel thing--it's hard to explain. The belt should deflect about an inch at it's widest point. Another way to tell is to twist the belt--you should be able to twist it 90 degrees but not more or less.

I did notice though you're missing a couple valve cover bolts. :)

Yeah I fixed them by the time I did my timing chain video series on this car. Some guy (me) had stripped them out (me) years back before he really knew anything about cars (me).

@trssho91 8 жыл бұрын

+50sKid it doesn't take much, I've got one weak thread on mine that I'll have to helicoil if I ever remove it again (and while I've broken or stripped my share of bolts, this one isn't my victim. It was already that way when I pulled the valve cover to replace the leaking gasket). I'll have to look up you're timing video sounds like a good watch. I feel for you on that job, just looking at it looks like a bad day. This is from someone who did a 2.5l ford probe timing belt in an afternoon. ;).
