the 1992 or 1993 tuned integra had been sitting in the garage for 6 months so i start my car and park it on the driveway, it wouldnt start again. We checked the timing belt, it was fine, but it was loose. So the belt tensor is messed up.
We need to get to it, i have a B16A2 i think (might be B16A1 but prob not) so can someone please let me know a good way to get to the tensor.
We tried going from behind the right wheel, but we couldnt get in (me and my dad). Anyone know a better way to get to the tensor? is it possible to just do it straight from above the hood after taking the engine cover off?

From the top, you'll need to remove the plastic timing covers and valve cover to get at the belt tensioner (pain in the *** while the motor is in the car), nothing complicated to changing or tightening it though.

You'll need to remove the accessory belts and crank pulley to remove the bottom cover.

All B16 motors have the same timing belt setup, model will not matter.

Here's what it looks like with the covers off with motor out of car (the tensioner has the green bearing seal), this is my b20-vtec, but its the same idea...

thanks so much
but wait, is there another way to do it?
my dad and i tried taking out the crank pulley, and some bolt just wont give so we cant. A mechanic recommended an air compressed drill to take out the bolt as we already tried an electric. Or is there another way to get to the tensor.
thanks again.

Can't get to the tensioner without removing the covers. I assume you mean that the crank pulley bolt wont come out? Yes, an air powered impact gun should do it. Heating it also does the trick.

yes as civtegra was saying the crank pulley had to come off first. This gives you complete access to all the cover 10mm bolts. You have to remove all the cover bolts and it will look like the picture he has posted. At this time set your engine timing and remove the timing belt followed by the tensioner. Once the timng belt is reinstalled make sure you tension the engine correctly. Rotate the engine slightly to confirm there is no to very little slack in the belt. Rotate the engine 2 full revolutions and confirm timing marks are aligned and belt is still tensioned correctly.

we tried heating the bolt, and it wouldnt budge with the electrical impact gun
so yea the air powered impact gun is our last bet
thanks guys

okay. DAMMIT.
the we tried 2 different strengths of air compressors with the impact gun, 110 psi and i think something around 170 psi (from my dads work truck) and it STILL wouldnt budge! this is so frusterating...
it wouldnt b a reverse thread would it? even if, im sure we tried the opposite direction with the electrical impact gun.
Is there no way to get to the tensor without taking out the crank shaft pulley bolt?

realistically you should be taking off the crank pulley. If you try and get the at tensioner otherwise it will be a big pain in the *** and you will most likely break the front cover, which you dont want. It is not so much your PSi going through the gun but its torque rating. Do you have a good gun on there? Anyways get a legit gun on there and get it off, or you need to heat it cherry red with an oxy actenlene torch. Maybe try 3/4" gun

damn, mine wasnt even that bad. I just heated it up with a small propane torchfor a few mins and loosened it off with a 4 foot bar on the end of a tire iron, lol

 
Rep Power: 746

maybe hes just a wimp hahhah just kidding man, there are many methods you can do to get the crank bolt off and one of them is bound to work.

and don't use any extensions! you'll lose all your torque. only use ones that are rated for impact guns.

 
Rep Power: 676

kinda have to use extensions...
i donno if the one we have is rated for impact guns.. how do u tell?

we tried the propane torch, didnt even budge.
as for the oxy actenlene torch... maybe our last bet? if not then i have to take it to
an actual mechanic?

You need something like this:


Or you can do a "hack" job by removing the flywheel dust cover and well, use your imagination.

yes the crank pulley too does help, but i think he is struggling with actually breaking free the crank pulley bolt.

 
Rep Power: 676

yea... the crank pully bolt won't freaking budge...
really frusterating that the car can't be fixed at the moment due to just one bolt....
