Common questions

Why is there a puddle under my car?

Why is there a puddle under my car?

The evaporator, under your dash or in the heater box, gets quite cold in operation, and the warm and humid air forced over it by the fan condenses and forms water droplets. The water is drained away by a scupper and hose, and this is the puddle you see under your vehicle.

Can a puddle of water cause a car to start?

There is a good chance that water got into the sensitive electronics of your vehicle. Having a trained professional inspect your vehicle is the only way to determine the exact cause of your starting problem. The statements expressed above are only for informational purposes and should be independently verified.

What happens if you run through a water puddle?

If the water was very deep and got sucked into the intake, then its possible that it can destroy the engine. Water is incompressible and if it makes it into the cylinder while running it can blow gaskets, or bend or brake your piston rods. Ok it took me a while to figure this out about my 1997 Honda Odyssey but I ran through a water puddle.

What happens if you drive through a deep puddle?

Notes: Water deeper than the bottom of a center line of wheel is too deep! If a true 10 mph – that’s just fast enough to water ski and would make quite a spash unseen perhaps. Sometimes air intake will suck in water and that can blow the engine! Thanks guys! Yeah the water wasn’t super deep…maybe about a foot or so.

The puddle under your vehicle can’t be due to an air conditioning leak. Why? Refrigerant, the substance that makes the air-conditioned air blow cold is actually a gas, not a liquid. So, if your vehicle’s air conditioning system springs a leak, it’s gas that goes into the atmosphere, not liquid forming a puddle under your car. So, what is it?
