What liquid is leaking from underneath my car? Ford Fusion Hybrid 2014

John Squire · 2 Apr 2020 at 08:41

Hi, I was wondering if anyone could advise on what liquid is leaking from underneath my vehicle.
I noticed a small pool of liquid a few days ago on my garage floor underneath where my car had been parked. So I put a metal tray with paper towel underneath to try and identify what it could be.

The leak is coming from just inside the rear drivers side wheel (I'm in the US so left hand side drive). I've attached a photo of underneath the car and another of the clear-ish liquid on the paper towel.

Anyone have an idea of what it could be?

Have you sniffed it? Where's your filler cap?

Does it have a rear windscreen washer bottle?
What does it smell like?

If it's colourless and odourless, then it's probably just condensate from your air conditioning.

For anyone that is confused, this is a Mondeo here.

Looks like the fusion drive has a crack in it and the fusion is leaking out.

shock oil ?

sovietspybob · 2 Apr 2020 at 10:11

Is it oily to the touch?

Could be brake fluid as that's clear, or oil from the shock? I guess you'd know if it was petrol as you'd smell it a mile off.

Looks like condensation draining out, anything else would have more of a colour to it on white kitchen roll I would have thought or you'd smell it if it was petrol.

Under a rear wheel? I know Yank cars are weird, but the AC’s still at the front.

Is that underneath the fuel filler? Any chance you overfilled with diesel, or ad blue? They usually have a little drain hole under the flap.

If not, I'd guess shock absorber.

No, because all Fusion Hybrids are petrol.

Cheers.

In that case - I'd be looking at replacing that shock. Looks similar to in this guys rant about the Mondeo and it's faults.

I hadn't spotted the rear wheel bit. Ignore my suggestion of air con related!

bobuk · 2 Apr 2020 at 15:00

I'd go for a leaking shock absorber

ezekial · 2 Apr 2020 at 23:39

It's a serious leak if it's a shock. But I cant imagine much else leaking there other than brake fluid.

That is where the rear lower spring cup is the damper is over a towards rear just out of shot. If a damper is leaking it will be a doddle to spot by looking underneath. Use a phone to video it with the light on.

if you bounced the rear you may discern if its the shock ... but looking in the wheel arch - yes
