Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello I will help,
The waterpump is inside the timing cover and it could be leaking down onto the steering pump. Can you dry the area and run it for just a few seconds to see if you can spot the leak?
Other alternative its to dry the area and use a cooling system pressure tester (autoparts stor loan a tool) to put pressure on a cold engine to see the leak.
Can you post pictures of the highest point you see the coolant?
