I am not really familiar with the external Torx sizes, although I admit I should have bought a set the day I bought the car since there are so many under the hood.


Just did my water pump and tstat this weekend. It is about a 3-4 hour job, and small hands are very helpful. The toughest part is removing the coolant hoses in a very small area. The Tstat is held by 2 10mm bolts and the Water Pump is held by 3 E10 torx bolts. The water pump bolts are very diffucult to remove as they are in a tight space. I couldnt have removed them without a 6 inch extension using a small 3/8 ratchet. good luck
