Hydrolock linked to hole in radiator?
Hi,
My car was booked in to get a small hole in the radiator fixed this morning. Yesterday I drove through a big puddle, about 30cm high. As did 100 other cars behind me and in front of me. My car stopped working. It had to be towed to a mechanic. Where upon he told me the car sucked up so much water it was hydrolock end and I need a whole new motor. My question is- if the radiator had been fixed prior to this would the car had sucked up that much water? Was the fan sucking harder to compensate the hard working radiator? Is there a link between the two? Thank you. |

There should not be any connection between the two, this has much more to do with speed you were driving, where did you get this idea?

The fan doesn't suck air (or anything else) into the engine. It merely pulls air through the radiator. Air (and in this case, water) is brought into the engine by the suction created when pistons move downward in the cylinders.

ABSURD ..... unless
the puddle was deep enough to submerge the exhaust tail pipe and the car stalled while in the puddle. Thermodynamics in that case is likely to cause water to back up through the exhaust system and potentially hydrolock through the open exhaust valves.
Of course however it had nothing to do with the radiator as others have pointed out. |

I would get a second opinion.

What kind of car is it? How fast were you traveling? If it sucked water into the intake it could have damaged the engine.

Indeed, another opinion is in order. Immersion of 30cm (12in.) would likely kill some of the electrics, but I am a bit skeptical about the claim of hydralocking. If that much water has entered a cylinder, removing the spark plugs, and turning the engine by hand should expel quite a bit of water.

Care to run your car through foot deep water to prove the diagnosis is absurd? He drove through 12" of water, any car with a front mount air intake can draw enough water into the air filter / intake / cylinders to at minimum stall the motor. But, there is a fine line between stalling the motor damage free and hydro locking it / bending a rod. |

The OP has posted once; there are now eight more that are not from the OP!
