Toyota Yaris Hybrid 2013 | Water Leak Detection

Video transcript

0:00 OK, today we have a Toyota Yaris in today, 2013, so we're just going to show you what we've found first of all. So if we concentrate on the back, first things first we're going to concentrate on the drivers rear light. So what we're going to do is we're going to pour a bit of our water just down on the top of this light, just simulating this out in the rain. And if we come on the inside, we can see that the water is passing through light gasket and then filling up the driver's rear box section. And then what we need to do is, if we

0:37 just turn this little flexi camera on. And what we've got is we've got our camera going up and behind the box section, which is looking at our rear air vent. So our rear air vents here in the box section. And so if we go on the outside, we're going to pour a bit of water just on the back of the bumper, and then what that should do is it should come in. And as we can see there, the water is coming through the air vent and then filling up the box

1:02 section. It's doing that on both sides. The rear light only on the driver's side is leaking, but both the rear vents are leaking. So it's filling up that box section. When it then fills up that box section, which is behind this panel, it would then work its way towards the front of the car on both sides as well, filling up the spare wheel holder. And if we just quickly come into the drivers rear footwell, we haven't pulled the carpet up yet, but if I just push down on here, we can see that we've got

1:35 condensation on our hands. And if I just quickly clean my hand again, so we've got a nice dry hand, on the passenger rear footwell, if we push down again quite hard, so we can see that there's moisture in the back foot wells. So what that's then done is it's followed the trail all the way down, use this, and then it's then started to fill up. And then what it's then done is it's worked it all the way to the front of the car. So I've just lift this bit of carpet up here, and it reveals a little bit of

2:05 underlay. And if I just lift the underlay up a second and give that a squeeze, so we can see how wet that underlay is under there. So that's soaked all the way to the front of the car. There we go, so we've got the water down there. And just quickly coming round to the passenger front, just to show that it's travelled all the way down the passenger side as well. So once again we've got this trim up, this carpet we can get up a bit higher. So we've got the underlay under here, and if we just pick this underlay

2:43 up and give it a squeeze, so that's completely soaked as well. So all of the carpet in the underlayer completely soaked, so we need to take all of the seats out to lift up the carpets and the underlays and suck it all out. The only issue is this is a hybrid, and underneath these back seats is all of the batteries for your hybrid system. So as we can imagine, from the leak from the boot and then coming to the front, obviously all the water will be around

3:11 your hybrid system. So we're gonna have to make sure that it's completely bone dry before we put it back together. And so that's everything we've found on that on so far, or we'll see if you...

It's no surprise that the rear air vents are leaking on this Toyota -- door membranes and rear air vents account for a huge amount of leaks on cars.

There's also a leak around one of the rear lights where the rubber gasket has shrunk with age... probably. Either way, we will attempt to fix this with a rubber reviver. This is much cheaper than ordering a new rubber set for the car. 

This car is a Hybrid and has batteries which are located under the rear seats. It should go without saying that water and electrics don't mix, and in the case of hybrid and electric cars it can be potentially dangerous, not least for anybody trying to work on them. Our staff have been trained on electric cars, been on the course, got the certificates etc. 

A lot of people, especially those watching these videos, want to try and fix the leaks themselves, which is fair enough. But please be aware that on modern cars there are some modern "issues". Aside from the explody things which can potentially cause you physical harm like the lithium batteries and air-bags, it is possible to do damage to the car, and it's delicate computer systems. Be careful out there.
