Volvo XC90 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 Volvo XC90 — and what it saves
The catalogued element for the XC90 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 | +$0.41 |
| Manitoba | 10.2 | $0.08 | $9.79 | +$0.38 |
| Ontario (avg TOU) | 12.8 | $0.10 | $12.29 | +$0.36 |
| Alberta | 14.0 | $0.11 | $13.44 | +$0.35 |
| Saskatchewan | 15.5 | $0.12 | $14.88 | +$0.34 |
| Nova Scotia | 17.9 | $0.14 | $17.18 | +$0.32 |
Natural Resources Canada rates the Volvo XC90 at 14.9 L/100 km in city driving (median across 2003–2026 model years). On a 20 km winter commute that is about 3.0 L a day. NRCan measured that at −20 °C a block heater improves overall fuel economy by as much as 10% — roughly 0.30 L, or $0.46 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.

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 XC90's oil pan is steel first: a magnet won't hold on aluminum or composite pans.

Digital multimeter with resistance and continuity
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

How much does it cost to plug in a Volvo XC90?
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 Volvo XC90?
Yes.
