Honda Civic battery: test, then match
Ask for a load test on the battery and a check of the charging system before anything is bought. If the alternator isn't charging, a new battery goes flat just like the old one did.
The MTA lists the usual culprits: lights left on, short trips that never recharge the battery, and a car that isn't locked with the remote, which keeps its computers awake and slowly drains it. An occasional longer drive, about once a month, helps a Civic that mostly potters around town.
A Civic Hybrid is different. Those built from 2003 to 2015 use Honda's Integrated Motor Assist, with a high-voltage battery as well as a 12-volt one. Only the 12-volt is a routine swap; the other is work for a mechanic trained on hybrid systems.
Civic cambelt or chain?
| Camshaft drive | What to do about it | |
|---|---|---|
| 1.8-litre R18, Civics from 2006 to 2020 | Chain | No routine replacement. Keep oil changes on time, and report any rattle from the front of the engine. |
| Older Civics and many Japanese imports | Depends on the engine | Have the mechanic identify the engine code and look for proof of a belt change in the history. |
| Type R with the 2.0-litre K20 | Check with the mechanic | Ask before assuming either way, and keep the receipts with the car. |
If your Civic does have a cambelt
The cambelt (a toothed rubber belt that keeps the valves opening in step with the pistons) wears out without any warning. On an interference engine, a snapped belt lets the pistons hit the valves, and that turns a planned job into an engine rebuild.
So treat an unknown belt as overdue until someone proves otherwise. The water pump is often replaced at the same time, because it's right there and wears too, and belts usually come in kits with the tensioner and idlers. A good quote lists all of it. More on the job in cambelt replacement.
Japanese-import Civics
Civics imported second-hand from Japan, like the FD1 version of the 2006 to 2011 car, often arrive with little paperwork. The AA's import buying guide says compliance usually includes a basic oil and filter change and nothing more, so the air filter, transmission fluid and spark plugs may be due.
Check for airbag recalls too. Consumer Protection says you'll need the plate or the 17-character VIN to look a car up under the compulsory Takata airbag recall, and to check again later if it's clear, since recall action can start afterwards.
If it were our Civic
Get the battery and charging system tested before buying anything. Then settle the belt question for good: the engine code tells you whether it's a chain, and if it's a belt with no record, we'd book the change rather than gamble the engine on it.
