Car Forum / Honda Cars / August 2004Timing Belt Question
My friend and I replaced the timing belt, water pump and balancer belt on my 98 Accord with a 4-cyl VTEC engine. Everything seemed fine and I've put about 100 miles on it since then, but now it seems the belt is making noise. It's kind of a whirring noise once the engine heats up. The sound is more noticeable at idle. I think we failed to adjust the belt tension properly, doe's this sound like that's the case? Also, I read it that you should not use an impact wrench to tighten the crank pulley bolt, which we did. Now, I 'm concerned we did some damage. What potential damage did we do? Thanks in advance.

If you do it right, you can reduce the tension without removing the TB covers, just the valve cover.(at least I _think_ you can on the non-Vtec) 'Curly The 12 V charger port is shut off when the car is parked.

I know I don't, and my '94 Civic has the same issue. I'm planning to rewire the cig. lighter so that it's always energized. Has anyone figured out the best point at which to tap into an energized positive line? I'm assuming that it's switched via the positive, and that the ground is always connected.

The under-dash fuse box has two connectors where you can get battery voltage. See http://www.honda.co.uk/owner/civicmanual/pdf/23-a36.pdf for a drawing of the UK fuse box, it differs slightly from the US one, but it is close enough for this discussion. Above the two rows of fuses you will see 5 options connectors, numbered from left to right, 1 through 5. On US models, the connectors are in a straight line rather than a zig-zag pattern. Number 1 (left-most) has constant battery voltage, fused only by a 50 Amp fuse in the under-hood fuse box. Number 2 has constant battery voltage fused by fuse #17. On Canadian models this fuse is a 10 Amp fuse used also for the DRL function. In the US the fuse is not installed. So, stick a fuse in there, and options connector #2 is a prime location for hooking up low-power accessories like a cell phone charger. In the interest of completeness, options connector #3 has battery voltage only with the ignition on, but not during start. Fused with 7.5 Amp fuse, number 16. This fuse is installed on Canadian models, not on US models. Options connector #4 has battery voltage whenever your parking lights or headlights are on, fused by fuse # 19, 10 Amp. Good location to hook up the parking light flash wire from alarm systems. Finally, options connector #5 has power with the ignition key in "ACC" or "Run", but not during start. Fused with fuse #23, 15A. Normal, 1/4" quick connects fit the options connectors. Post a valid e-mail address if you want a photo of the US fuse box with options connectors marked. Several other Hondas ('96 Accord, Accura Integra) has similar options connectors. I would be shocked and dismayed if the 2004 Civic didn't have them as well. > So, stick a fuse in there, and options connector #2 is a > prime location for hooking up low-power accessories like a cell phone > charger. Awesome, Randolph. Thanks for breaking down the schematics for those option connectors. It's nice to know I've got an easily accessible option that I can fuse appropriately. I just reviewed the electrical schematics in my Helm manual and see exactly what you're referring to. How accurate are those schematics, though? For example, my 94 manual on p. 23-70 omits the under dash fuse #23 that is listed on p. 23-63 as supplying the radio--just shows an unfused path from the under hood fuse #32. Also, it doesn't make much sense that the under hood fuse #32 is listed at 7.5A, yet the under dash fuse #23 that it supposedly supplies is listed at 15A. Gives me some cause for concern. > > So, stick a fuse in there, and options connector #2 is a > > prime location for hooking up low-power accessories like a cell phone [quoted text clipped - 11 lines] > listed at 7.5A, yet the under dash fuse #23 that it supposedly supplies > is listed at 15A. Gives me some cause for concern. I also have the 94 Helms manual for my '94 Civic. I have added a fair number of electrical accessories over the years, and have not found any discrepancies in the wiring diagrams. As to your specific concerns, page 23-70 shows the memory keep-alive power supplied to the stereo. It is indeed fused by the 7.5 A fuse (#32) in the under-hood fuse box (same fuse as for the clock and the ECU memory backup, hot at all times). Fuse number 23, listed on page 23-63 supplies the operating voltage to the stereo (hot only with ignition on), as shown at the top of page 23-69. Page 23-224 (or 23-225) brings it all together and shows both supply paths. The only frustration I have with the wiring diagrams is that, although they are accurate, they omit wiring not relevant to the current section. E.g. on page 23-69 the manual show power being supplied from fuse #23 to the stereo, the lighter and the options connector, yet on page 23-224 there is no mention that both the WHT/BLU and the WHT/BLK wires go other places in addition the the stereo. It would have been convenient if each of the section would stick a label on the relevant wires, indicating that "this wire goes to other stuff as well". > As to your specific concerns, page 23-70 shows the memory keep-alive > power supplied to the stereo. <snip> Fuse number 23, listed on page 23-63 > supplies the operating voltage to the stereo Aha, that makes lots of sense and didn't occur to me at 1 a.m. Something obviously has to keep the presets alive and the anti-theft light flashing... > It would have been convenient if each > of the section would stick a label on the relevant wires, indicating > that "this wire goes to other stuff as well". It may be that the separate Electrical Troubleshooting Manual has more complete schematics--the blurb says it does: Written by Honda, this book has the most in-depth wiring diagrams available. Information on how to troubleshoot electrical problems, this manual includes circuit schematics, power distribution schematics, ground distribution schematics and component locations to accurately repair electrical problems. ETMS are model and model year specific, and their schematics are far more detailed than the wiring diagrams in the Service Manual. For best repair results, use this manual in conjunction with the Service Manual. <<< Only $39, printed to order. Just head over to Helm, it's listed along with all the other manuals available for our model. Abe |
