What's wrong?
The radiator on a 2007-2010 Nova Bus Nova Lfs bus is part of the engine cooling system. It helps carry heat away from the engine by moving coolant through the radiator assembly. Small O-rings seal connection points in that assembly so coolant stays inside the system under heat and pressure.
In this recall, the roof mounted Modine radiator was built with the wrong type of O-ring at certain locations. Nova Bus says those seals must be Viton type O-rings. Viton is the specified material for this application, so the wrong seal material leaves the radiator assembly with seals that do not match the design requirement.
There is no warning sign before failure. The filing does not identify a reliable sound, light, smell, or driver symptom that appears before the O-ring problem shows up, so the VIN decides whether the bus is included.
Who's affected?
Spans the 2007, 2008, 2009, and 2010 model years, all tied to the radiator assembly.
| 2009 Nova Bus Nova Lfs | Radiator assembly |

| 2010 Nova Bus Nova Lfs | Radiator assembly |
| 2008 Nova Bus Nova Lfs | Radiator assembly |
| 2007 Nova Bus Nova Lfs | Radiator assembly |
| Units affected | 104 |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
Deteriorated O-rings can let hydraulic oil leak or seep from the system. The recall does not list a warning sign, so treat visible oil seepage or fluid loss as a reason to stop using the bus and call a Nova Bus dealer. Repair will be free at any franchised Nova Bus dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2010 Nova Bus Nova Lfs is included in this recall.
- Contact Nova Bus customer service at 450-472-6410 and ask whether the free Viton O-ring installation has been completed for your bus.
- Reference recall number 10V132 when you call or speak with a Nova Bus dealer.

What happens at the repair
The source remedy says dealers install Viton O-rings free of charge, and the safety recall began on May 11, 2010. At the dealer, a Nova Bus technician replaces the incorrect radiator O-rings with Viton O-rings at the affected roof-mounted radiator locations. Parts and labor are covered by the recall. If the service desk cannot confirm current parts availability from the filing alone, ask them to verify the remedy before bringing the bus in.
