Volkswagen Jetta 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 Volkswagen Jetta — and what it saves
No supplier lists a wattage for every Jetta element, so this uses the 1000 W figure typical of this body style. 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 | $0.14 | $16.80 | +$0.18 |
| Manitoba | 10.2 | $0.20 | $24.48 | +$0.12 |
| Ontario (avg TOU) | 12.8 | $0.26 | $30.72 | +$0.07 |
| Alberta | 14.0 | $0.28 | $33.60 | +$0.04 |
| Saskatchewan | 15.5 | $0.31 | $37.20 | +$0.01 |
| Nova Scotia | 17.9 | $0.36 | $42.96 | −$0.04 |
Natural Resources Canada rates the Volkswagen Jetta at 10.4 L/100 km in city driving (median across 1995–2026 model years). On a 20 km winter commute that is about 2.1 L a day. NRCan measured that at −20 °C a block heater improves overall fuel economy by as much as 10% — roughly 0.21 L, or $0.32 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.

Block heater recalls on the Volkswagen Jetta
Transport Canada has recorded 3 recalls on the Jetta that involve the block heater or its cord. Check your VIN before you buy parts — if your vehicle is affected, the repair is free.
Issue: On certain vehicles, the warning label for the engine block heater cable is written in English only. As a result, a French user may not receive important safety information about how to use the engine block heater. A label that is not provided in both official languages could create confusion. Safety Risk: User confusion could increase the risk of injury when trying to use the block heater. Corrective Actions: The company will mail each owner a new label for the block heater cable. If you would like help installing the label, you can contact a dealer for assistance.
On certain vehicles equipped with a factory installed block heater, the block heater could overheat while in use. This could result in a fire causing injury and/or property damage. Correction: Dealers will replace the block heater. Owners are advised to stop using the block heater in the interim.
On certain vehicles, the factory installed block heater could overheat during use, which could increase the risk of fire causing injury and/or damage to property. Correction: Dealers will inspect and, if necessary, install a new block heater.
Issue: On certain vehicles, a software problem could cause the rearview camera image not to display or cause it to freeze. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear. Safety Risk: A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash. Corrective Actions: Volkswagen will notify owners by mail and instruct you to take your vehicle to a dealer to update the rearview camera software.

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 Jetta'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 $60–$180 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 Volkswagen Jetta come with a block heater?
Dealer/aftermarket 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 Volkswagen Jetta?
The recommended setup is a inline coolant heater (typically 600 W). Frost-plug access is tight on many VW four-cylinders, so inline coolant heaters are the common route — including on the TDI diesels, where pre-heating matters most.
What is the block heater part number for a Volkswagen Jetta?
1.8L 4-cyl: Zerostart kit 3100034 with cord 3600016; 1.9L 4-cyl diesel: Zerostart kit 3100034 with cord 3600016; 2L 4-cyl: Zerostart kit 3100034 with cord 3600016. Confirm displacement and model year against the fitment table before ordering.
Where is the block heater cord on a Volkswagen Jetta?
Varies with install; typically routed to the grille.
How much does it cost to plug in a Volkswagen Jetta?
At 1000 W on a two-hour timer the heater uses about 2.00 kWh a night — roughly 26¢ in Ontario, 28¢ in Alberta and 14¢ in Quebec. Over a 120-night winter that is about $33.60 at Alberta rates.
Does a block heater save fuel on a Volkswagen Jetta?
Yes. Natural Resources Canada rates the Jetta at 10.4 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 0.21 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.
Is there a block heater recall on the Volkswagen Jetta?
Yes. Transport Canada has 3 recalls on file for the Jetta involving the block heater or its cord — starting with recall 2020353. Check your VIN in Transport Canada's recall database before buying parts; if your vehicle is affected the repair is free.
