On Volvo D16 engines, the front timing cover and thermostat seal are precision-dependent. The ATC 9998318 provides the mechanical leveling force needed to ensure a leak-free assembly every time.

The Dual-Function Challenge

The Volvo D16 platform features a unique design where the thermostat seal is housed directly within the front timing gear cover. This means that if the cover isn't perfectly level during assembly, the seal will never seat squarely. The ATC 9998318 is an application-specific press that handles two critical tasks: leveling the timing cover and driving the thermostat seal to its precise depth.

• Even Pressing Force – Eliminates the "cocking" of the seal that occurs with hand-pressing or generic drivers.
• Timing Cover Leveling – Acts as a leveling fixture to ensure the front cover is perfectly aligned with the engine block during installation.
• Zero Distortion – Precision-machined to apply force to the seal’s outer diameter, preventing the rolling or tearing of the sealing lip.
• Coolant Leak Prevention – Ensures a 100% mechanical seal at the thermostat housing, a common leak point on D16 FM series trucks.
• Heavy-Duty Precision — Built from high-strength materials to survive the rigors of a professional fleet maintenance shop.

Precision Tooling for D16 Overhauls

The ATC 9998318 Leveling Press is an essential investment for technicians working on heavy-duty Volvo trucks. By standardizing the front-cover assembly process, you reduce the risk of coolant contamination and expensive redo labor.
