USA '04 Tundra Disappearing Power Steering Problem Help!

Hello, my '04 Tundra has an unusual problem with the power steering. The power steering fluid (dex/merc) gets low all the time and I add half a quart here and half a quart there. Naturally you would think there was a hole in a hose or a loose fitting or something but there is not. Some of the hoses and a sensor on the front of the pump look like they have seen oil but nothing like the amount of fluid being lost is found in the engine compartment or on the ground underneath it. Can anybody help me find out where all the fluid is going?!?!!? Thanks -Benjamin

You have a leak.

You may not see it until there is a load on the steering, or only at certain rpms.

So, add a dye and find the leak.

Use valvoline maxlife ATF. Should help with tired seals.

mine would leak from the hoses leading from the cooler. They are held in place with those little clip on hose clamps. the leak was very slow and hard to notice. Most people wouldn't even know that there was a power steering pump cooler. it's just a little loop in the system in front of the a/c core.

There is a vacuum valve at the power steering pump that can get an internal leak. This causes the fluid to be sucked into the intake system and burned in the cylinders. If you don't see any leaks, this is likely your problem.
