By the time I got the car back home the front passenger floor board was soaked. The average cost to replace an axle seal in a non-4-wheel drive vehicle would range from $200 to $400 US dollars. Where it is coming from may take a bit more work but figuring out what fluid it is first half the battle. Check the crossmember, see if it's wet. It just started and it's a fast leak on the passenger side of my car. It seems to be coming from somewhere where the waterpump meets the block. Leak under front passenger side of car. Coolant or water leaking in front of Q1 I drove for about 30min is stop and go traffic the other day and when I parked in a angled parallel parking spot I opened my door to find water had run off my under pan and raced across the parking lot.
