I'm getting a P0401 Insufficient EGR flow DTC and I plan to unbolt the intake manifold according to TSB 99-085.

Question:

What size bolts attach the intake manifold to the engine block? (10mm, 12mm, 14mm)? Will i need a breaker bar or extensions?

I don't have any metric tools and will need to buy some just for this job. Ideally, I can buy the just ones I need and will have them on hand so I don't get stranded half-way into the job by missing a key tool.

Thanks for any suggestions.

 

Yeah you could just get the 'short' set [8 thru 19mm] of sockets from like sears or a parts store.
The 10 12 and 14 are the most common bolts on the Honda and I'm sure you could do the job with those sockets and wrenches.
Get a 6" extension to.
Craftsman/ sears has a long handle flex head 3/8" drive ratchet with life time warranty

 

might wanna grab a breaker bar if you have the cash while you're there for other jobs too.

 

thanks for all the replies, i think i found a mechanically inclined friend who might be willing to lend me his tools.

the breaker bar and the short mm set are good ideas. i did look at home depot but hadn't gotten around to sears yet.

i will probably have to get my own 10-80 or 10-100 lb-ft torque wrench.
