Coolant recovery tank
 

I was looking under the hood and couldn't find it. Does anyone know where there located on 08 3.3 santa fe and the oil filter? Also noticed that when I go in reverse down my driveway and then forward it clunks when it hits second gear only for a second and then is fine and only does it when its a cold start.

The graphic is from page 6-3 of the owner's manual. The tank is located under the cap shown next to the passenger side fender wall. The oil filter on a Lambda V6 engine is located on top of the engine. You have to remove the engine cover to see it. The filter is a cartridge style located in a housing that will be towards the rear of the motor next to the fire wall with a black plastic dome cap on top.

I would check the fluid level in the transmission.

Below is a link to the procedure for the 3.3L in the Sonata but it's the same on the Santa Fe.
