Honda Civic engines & block heater part numbers
Engine list built from Natural Resources Canada model-year data. Part numbers are catalog candidates unless a source review is shown for that application. Confirm the exact engine code, model year and installation port before ordering; an Amazon listing match does not confirm vehicle fitment.

Reading the numbers: Zerostart 31/35- is the heater kit, 36- the detachable cordset ("lit" glows when the outlet is live). Kat's 11xxx is an element, 28xxx a cordset, 24xxx a pad. Location codes are the manufacturer's (LF = left front of block).

What it costs to plug in a Honda Civic — and what it saves
The catalogued element for the Civic draws 400 W. Natural Resources Canada recommends a timer that runs the heater two hours before you drive rather than all night — that is what the numbers below assume.
| Province | ¢/kWh | Cost per 2 h plug-in | Full winter (120 nights) | Net per day |
|---|---|---|---|---|
| Quebec | 7.0 | $0.06 | $6.72 | +$0.20 |
| Manitoba | 10.2 | $0.08 | $9.79 | +$0.18 |
| Ontario (avg TOU) | 12.8 | $0.10 | $12.29 | +$0.16 |
| Alberta | 14.0 | $0.11 | $13.44 | +$0.15 |
| Saskatchewan | 15.5 | $0.12 | $14.88 | +$0.14 |
| Nova Scotia | 17.9 | $0.14 | $17.18 | +$0.12 |
Natural Resources Canada rates the Honda Civic at 8.4 L/100 km in city driving (median across 1995–2026 model years). On a 20 km winter commute that is about 1.7 L a day. NRCan measured that at −20 °C a block heater improves overall fuel economy by as much as 10% — roughly 0.17 L, or $0.26 of gasoline at $1.55/L. On a single short trip at −25 °C the saving can reach 25%. In most provinces the electricity costs less than the fuel it saves; in the priciest it roughly breaks even, and you still get the wear, defrost and cabin-heat benefits.

Canadian buyer checklist
Three checks before spending money
1. Check for a cord
Dealer installs route the cord through the lower grille.
2. Match the engine
Confirm displacement, fuel and model year against the table. OEM accessory numbers can vary by VIN and market.
3. Check recalls
Search the VIN in the Transport Canada database before using an unfamiliar factory heater or cord.
No exact-fit listing? Use the three-question heater selector for a safe fallback.
Where to look for the Honda Civic block heater cord
Dealer installs route the cord through the lower grille. Use a flashlight from above and through the lower grille, then check behind the bumper cover without pulling on an unidentified wire. A factory cord may be capped and clipped or zip-tied out of sight.
Found damage? Use the cord identifier before choosing between a plug-end repair and a complete cordset.
No tools? The stick-on option
If you'd rather skip the install entirely, a magnetic heater grips any flat steel surface — oil pan, block, transmission pan — and moves between vehicles. Check that the Civic's oil pan is steel first: a magnet won't hold on aluminum or composite pans.
Amazon buying options

The definitive block-heater test tool. Any meter with an ohms range and audible continuity can isolate a dead cord from a failed element.

First: check whether you already have one
Canadian-market vehicles are often fitted at the port or dealer and then forgotten by the next owner, so check the cord location above before you buy anything. If a cord is there, test it — a dead element and a dead cord look identical from the outside.
If you need one installed
Budget $40–$120 CAD for the part plus about an hour of labour, and book in October — Prairie shop calendars fill after the first cold snap.
FAQ
Does the Honda Civic come with a block heater?
Dealer-installed accessory in Canada. Check behind the grille for a coiled cord before buying anything — many Canadian-market vehicles have a heater installed that the owner never knew about.
What block heater fits a Honda Civic?
The recommended setup is a frost plug (cartridge) block heater (typically 400 W). Honda Canada sells a genuine engine block heater kit for the Civic — a common dealer add-on in the Prairies. The 1.5L turbo runs long warm-up cycles in deep cold; pre-heating shortens them dramatically.

Where is the block heater cord on a Honda Civic?
Dealer installs route the cord through the lower grille.
How much does it cost to plug in a Honda Civic?
At 400 W on a two-hour timer the heater uses about 0.80 kWh a night — roughly 10¢ in Ontario, 11¢ in Alberta and 6¢ in Quebec. Over a 120-night winter that is about $13.44 at Alberta rates.
Does a block heater save fuel on a Honda Civic?
Yes. Natural Resources Canada rates the Civic at 8.4 L/100 km in city driving, and found that at −20 °C a block heater improves overall fuel economy by as much as 10% — about 0.17 L on a 20 km winter commute. On a single short trip at −25 °C the saving can reach 25%. In most provinces that is worth more than the electricity it costs.
