Chevrolet Express / GMC Savana 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 Chevrolet Express / GMC Savana — and what it saves
The catalogued element for the Express / GMC Savana 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) |
|---|---|---|---|
| Quebec | 7.0 | $0.06 | $6.72 |
| Manitoba | 10.2 | $0.08 | $9.79 |
| Ontario (avg TOU) | 12.8 | $0.10 | $12.29 |
| Alberta | 14.0 | $0.11 | $13.44 |
| Saskatchewan | 15.5 | $0.12 | $14.88 |
| Nova Scotia | 17.9 | $0.14 | $17.18 |

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 Express / GMC Savana's oil pan is steel first: a magnet won't hold on aluminum or composite pans.

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.
