Frequently asked questions

What is the DA4751 aluminium header tank?

The DA4751 is a coolant expansion (header) tank for the Defender cooling system, fitted in place of the moulded plastic original. The TIG-welded aluminium tank mounts in the standard position and retains the original pressure cap, so it's a direct replacement.

Which Defenders does the DA4751 header tank fit?

The DA4751 fits the Land Rover Defender Td5 (1998-2006) and the TDCi Puma (2007-2016). It bolts into the standard header tank location for those engines, suiting the Td5 and 2.2/2.4 TDCi cooling layouts. Check which system your Defender has before ordering.

Why fit an aluminium header tank instead of plastic?

The DA4751 aluminium tank replaces the plastic original, which can split and weep with age and repeated heat cycling. Aluminium resists the cracking common on the old tanks, so it's a popular upgrade when the original starts leaking or as preventive maintenance on the Defender.
