Idler pulley #2 or lowest one on the engine of a 2017 tacoma sr5 4x4 replacement procedure

Hi everyone on the above vehicle I got stuck because the bottom or a lower idler pulley froze up it is behind the oil filter housing or oil cooler as some people are calling it I think that the oil cooler have to come off the engine block in order to replace this pulley has anyone done it yet I couldn't find it thread plus I have no torque specs on the oil cooler or the pulley any help would be appreciated

 

Are you sure it's No.2?


2GR-FKS

 

It's a 3rd gen I believe it's #2 behind the oil filter housing its the only one that can't taken off easily

 

The problem is the oil housing prevents just removal without removing it I don't know if that procedure would be extensive or what the torque specifications would be do I drain the oil or will it stay in the pan ?

 

I guesstimate you'd loose only the oil in the cooling space...since it's higher than the oil pan. But still a mess...

 

Well that's the right view .....any idea what it entails taking it apart any thing I should be thinking about before removal or torque specifications for the oil housing or the tensioner? I do have to remove the entire cooler not just the top

 

4 cyl?
32 ft-lb on the idler pulley
15 ft-lb for the 2 nuts and bolt on the oil filter assembly

 

6 cyl

 

Should be the same I guess and thank u for your reply

 

30. INSTALL NO. 2 IDLER PULLEY SUB-ASSEMBLY
(a) Install the 2 No. 2 idler pulley sub-assemblies with the 2 bolts.
Torque: 43 N·m {438 kgf·cm, 32ft·lbf}

HINT: "DOUBLE" is marked on the idler pulley to distinguish it from the No. 2 idler pulley.

 

Did the job today all went as planned except the belt routing it is wrong I will post the proper routing tomorrow

 

Yours or mine, on your Tacoma?

 

The one toyota gave me is wrong this is the right one

 

So you never looked at my post....

 

Reviving old thread.... Can you not drop the skid plate and do this relatively easily from underneath or is the oil cooler still in the way? For the lower pulley

 

It is still in the way per photo--taken from above but doesn't matter: you cannot replace the lower idler without pulling the oil filter mount. I've seen good engineering and I've seen bad, but this is just malicious engineering: these vehicles are intended to be used offroad and exposed to adverse environments like mud, sand, grit, etc. My idlers needed replacing at 60K even though my engine is protected by full length skidplates. But unless you have the foresight to pack an extra gasket and can figure out how to clean the crap off a dirty, oily exposed engine part, you ain't gonna do a field repair on this. I was ticked with the brake light leak that Toyota left on the backs of owners and I've long hated the stupid two-piece oil filter, but this pissant design is sending me to other brands when I (soon) replace the Tacoma.

And adding to all this, I added the Tacoma to my AllData subscription--and discovered that Toyota doesn't even give any instructions whatsoever to remove the oil filter mount. That means that 2021 Toyota is providing less information to users than Jeep did for my 2006 Wrangler. To me these are all signs of a company that rests on its past and doesn't care about the present or its customers....
