8-hose silicone cooling kit BMW E36 325i M50B25 integrated expansion tank — REDOX

REDOX 8-hose silicone kit for the complete cooling circuit of the BMW E36 325i (M50B25 straight-six 24V 192 hp, 1990-1995). This configuration uses a radiator with integrated expansion tank (specific to early E36 pre-facelift), a key identifier for the correct kit.

Kit content

Upper and lower radiator hoses, two heater core hoses (feed/return), expansion tank breathers, and water manifold/pump/head connections specific to M50B25. Mandrel-moulded to OEM geometry.

Technical construction

• 3-ply VMQ silicone REDOX
• Polyester woven reinforcement
• 4 mm wall
• -60/+180 °C continuous
• 65-75 Shore A hardness
• Compatible with BMW G48 and all glycol coolants

Benefits vs OEM

On 30+ year-old E36, OEM rubber hoses almost always show hardening, cracking and expansion-tank leaks. Silicone VMQ offers long-term thermal stability, shape memory and superior ozone/UV resistance. The plastic expansion tank remains a watch point - replace with the kit.

Delivery

Supplied with W4 stainless clamps. Plug-and-play.
