ok -- i'm at 30k on my 06, and have decided to replace both low and high pressure filters. i've read here and there that neither filter change is all that advanced for a decent home garage mechanic. i feel that i've also read that no-one but a trained CNG specialist should do them. if YOU have actually done one of these, i would like to get the exact protocol from you, as well as any suggestions/advice. if you have only 'heard' something about something ... please don't reply, as i've also 'heard' the same something (probably). based on what comes back, i'll either attempt it, or take it in to the shop. thank you very much, brian (epi)

Replying to: rojak (Mar 27, 2008 9:01 am) The CA SULEV rating is available to the manufacturer who wishes to make the vehicle qualify , and wishes to warranty for that long. It is not a mandatory rating. The generation 7 (01-05) and generation 8 (06 and later ) sold in those states do , and will be on the emmisions sticker under the hood. The rating is also only for the GX first sold in CA and I think MA, and NY. If you take it to other states, the federal warranty applies. On the fuel injectors, You could call Honda Customer Service and tell them a sad story and how much you love Honda products..... They may split the cost , like Honda pays for the part and you pay for the labor. Remember they have to listen to people complain ALL DAY EVERY DAY , and do not have to do this ,so be polite when you call ! If that does not work out , internet Honda parts dealers like Bernardi, Majestic, or hondapatrscheap.com will sell them for about $350 each. 30% off list price. I have purchased from all 3 . |

Replying to: epnfrn (Feb 21, 2008 12:15 pm) I have changed both on my generation 7 (01-05). The high pressure one is the same on all years to present. other than having to fabricate a tool to properly re-torque the housing cover to factory spec ( 30 ft lb) , it was no harder than changing spark plugs. 20 minute job, including r and r of the tank brace/filter cover. The low pressure filter on the 01-05 is a spin -on , exact same size as the oil filter , but it's red and has a thicker shell and different seal. NOT interchangable with an oil filter. On the 06 and later , I think the low pressure filter is an element in a housing. Never seen or done that one. The last time I changed filters , they were VERY clean and prob. did not need to be changed. Any southern california member of cngchat.com can borrow the tool from me , no charge. send a pm on that forum . Also can e-mail photos and info from the gx service supplement. J.L.

Replying to: fbaldwin (Jan 08, 2006 7:03 am) Close the CNG shut-off valve (every GX driver should know where this is, behind the left rear wheel). Let the car idle until it shuts off by itself. Here's the tricky part. Find a 2' long oil filter wrench. Unscrew the old oil filter and put the new one on. Open the valve, check for leaks, and start 'er up. |

I have just purchased a 2007 Civic GX and after about 30 miles the engine has started to make a noise like one of the valve or tapits is out of adjustment. i took it to the dealer, and they said that all the GXs make this noise becuase the magnet in the injector is larger. Has anyone else ever heard of this, and do any of your cars sound like a clock when you drive it? Thanks, joe |
