Coolant Overflow Resevoir Replacement

The overflow reservoir for the radiator coolant shows cracks and brittleness after 10 years cycling temperature and pressure.


You will need to purchase a new replacement overflow reservoir as shown below for about $60.

 
You should drain the coolant and replace it with new. But I was too lazy to remove the engine shield, so I skipped that step and tried not to spill any coolant. Grab the reservoir and wiggle it out by pulling it upward.
 

 
 Use vise grips to crimp the bottom hose and the top hoses to prevent spillage. Use nose pliers to loosen the hose clamp and pull out the hoses. Start with the top two hoses and orient the reservoir so the coolant inside the reservoir does not spill out.


Replace the old reservoir with the new one and reconnect the hoses. Fill up the coolant to the Max line.

  1. I bought a 2006 S40 a few weeks ago and it needs a fair bit of work. I just discovered your blog and wanted to say thanks for putting all this info up. It's going to help me out a lot.
