What's wrong?
The engine block heater on these 2019 International CV trucks is an option that warms the engine coolant before a cold start. A power cord plugs into a standard outlet, runs to a heating element threaded into the engine block, and warms the coolant overnight so the diesel starts cleaner and faster in cold weather. The cord connects to the heater through a set of terminals at the engine.
On affected trucks, coolant can leak from the block heater itself and reach those cable terminals while the cord is plugged into an outlet. When coolant touches the energized terminals, the connection short-circuits. That short can damage the heater, the cable, and nearby engine components, and it can trip the circuit breaker or blow a vehicle fuse.
Warning signs include smoke or a burning smell near the front of the engine, weak block-heater performance on cold mornings, tripped breakers or blown fuses when the cord is plugged in, visible damage to the heater or its cable, and coolant pooling under the truck.

What's the safety risk?
A short circuit in the block heater can damage engine components and start a fire. Watch for smoke, a burning smell, tripped breakers, blown fuses, or coolant pooling under the truck, and stop using the block heater if any of those appear. Repair will be free at any franchised International dealer once International opens it.
What should I do?
- Check your VIN to confirm your 2019 International CV is included in this recall.
- Wait for Navistar's second owner letter, which confirms the final repair is ready to schedule. The remedy is interim, so the free engine-block-heater replacement is not yet available.
- Contact a franchised International dealer once the second letter arrives to schedule the free engine-block-heater replacement that fixes the short-circuit and fire risk.
- Avoid plugging in the engine-block heater until the replacement is complete, since the cord or terminals can short-circuit and damage engine components.
- Call Navistar customer service at 1-800-448-7825 with questions and reference recall number 19V372 (Navistar recall 19508) when you call.
What happens at the repair
Until the final dealer repair is available, the recall remains in interim status. Once International opens the final repair, an International technician will replace the engine block heater on the affected CV truck, free under the recall. Parts and labor are covered. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, since the affected trucks are within their original warranty period. Ask the service desk how warranty coverage applies if you have prior repair paperwork for the block heater or its cord.

Frequently asked questions
What is recall 19V372?
Recall 19V372 covers 705 2019 International CV trucks equipped with a Duramax 6.6 liter diesel engine and the optional engine-block heater (feature code 12XBL). The heater cord or its terminals can short-circuit, damaging engine components and increasing fire risk. International dealers will replace the block heater for free.
What should I do if my 2019 International CV is on this recall?
Check your VIN to confirm your specific truck is included in recall 19V372. If it is, contact a franchised International dealer to schedule the engine-block-heater replacement once the final remedy opens. Reference recall number 19V372 when you call. You can also reach Navistar customer service at 1-800-448-7825.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to perform the recall repair at no cost. Navistar will replace the engine block heater free of charge at any franchised International dealer once the final remedy parts are available.
Can I keep driving my International CV before the repair?
The recall does not carry a do-not-drive order. The short-circuit risk centers on the engine-block heater circuit, so owners concerned about fire risk can avoid plugging in the block heater until the dealer completes the replacement. Check your VIN to confirm inclusion in recall 19V372.
When will the final repair be available?
The remedy is interim. Navistar mailed an initial owner notice on May 31, 2019, and the recall began November 14, 2019. A second letter will be mailed once the final block-heater parts are ready.
