Moroso 01-06 BMW E46 M3 Coolant Expansion Tank - Direct Bolt-In Replacement

$433.99
Description

Moroso coolant expansion tank for the 01-06 BMW E46 M3. A fabricated aluminum tank replaces the factory plastic reservoir that goes brittle and splits with age and heat. Aluminum handles underhood temperature and pressure that plastic does not, and it is the part you stop worrying about on a track weekend.

Details

  • Application: 01-06 BMW E46 M3
  • Fitment: Direct bolt-in replacement — uses the factory mounting points and hose connections
  • Manufacturer part number: 63793

Worth knowing

  • Plastic expansion tanks are a common failure point on hot-running and tuned cars; replacing one before it lets go is cheaper than the tow.
  • Refill and bleed the cooling system properly after fitting, and check the cap seals against the new tank.
