2008 Pontiac Solstice Repair Question
What type of damage would the engine of a soltice gxp sustain from being driven into water about a foot deep?
Answer
For a small fee get a professional auto technician to go thru it in and out to assess the damages
What you're referring to is called "hydrolock". Water doesn't compress like air does so the water will stop the pistons. I doubt that has caused that much damage. First of all, water should not have gotten into the fresh air intake from just one foot of water. Second, if he was going fast enough to splash water up that high, some air would still have gone in. The water would stall the engine but the chance of damaging a piston or connecting rod would be pretty small.
What does it sound like now when you try to start the engine? If it cranks normally, I would remove the spark plugs and let it sit for a couple of days to dry out. Check the oil level too. If it is too high, water might have worked its way into it. Change the oil and filter, then change it again once the engine is running.
There is an entirely separate issue with the battery going dead. General Motors is one of the most customer-unfriendly manufacturers in the world. They have purposely designed in many things to separate owners from their money after the sale, and the battery issue is one of the best-known. Running the battery dead, or simply disconnecting it to replace it can lock up numerous computers and the radio. Often the car must be towed to the dealer to have them unlocked. In addition, they had a 100 percent failure rate of their cd radios. Since the '94 model year, GM has refused to sell us radio service manuals or parts so you are tied to their two grossly over-priced repair centers. A typical repair bill is around $450.00. To avoid that, a lot of people installed high-quality aftermarket radios. Now, to fight back, GM has been building the Body Computer into the radio so you must pay to have it repaired for the car to run. There is absolutely no legitimate reason to do that except to cost people money. There are so many of these "got'chas" built in that people are getting stung with that GM is having a hard time finding repeat customers.
