Nissens 996236 Coolant Expansion Tank with Sensor

The Nissens 996236 is a premium aftermarket coolant expansion tank designed to OE quality standards for reliable engine cooling system performance. This essential component maintains proper coolant pressure by absorbing excess fluid during thermal expansion, helping to prevent system stress and potential overheating.

Key Features:

• Manufactured from high-quality plastic material for superior heat and stress resistance
• First Fit configuration includes pre-mounted sensor for quick installation
• Rigorously tested for vibration, pressure-impulse, thermal expansion, and burst resistance
• Advanced welding process ensures strongest possible connection and leak-free operation
• Each tank is individually leak tested before shipment
• Reinforced fittings provide secure, consistent fit for long-lasting durability

Nissens expansion tanks undergo comprehensive development testing to eliminate the risk of leakage or insufficient cooling performance. The tank helps reduce coolant hammer, protects engine cooling system components from excess pressure damage, and redistributes coolant back into the system when pressure drops. This direct replacement meets OE specifications and cross-references to multiple Jaguar part numbers including C2C39438, C2C41899, C2Z13764, C2Z22872, and C2Z29118.
