    Head gasket blown

    I have a 2012 1.4 turbo with 150k highway miles... relatively trouble-free for last few years... recently changed water outlet, but reused coolant line back to reservoir...long story short, that blew apart, coolant gone and car overheated. Pulled over and shut off immediately... fixed hose and refilled, but exhaust gas bubbling through coolant tank bottom hose. Mechanic wants to install new head gasket, machine the head if it's not cracked, new water pump, and new timing chain. $3k. New engine is $6-7k or I can try getting a salvage and do it myself (he won't put in used engine). Anyone else had this problem? Shame to scrap this car, but I'm pretty close.

    Welcome Aboard!

    Water pump is an extended warranty item on earlier models, not sure about yours.

    150K/10 year warranty on the Cruze Water Pump?

    You normally need to burp the coolant tank a few times after a refill. Make sure that is not one of the issues. I would think you could do a compression test to find out if the block is compromised.

    Call the dealer for a engine quote.

    Someone blew a piston that dealer wouldn't warranty. Cost him $3500 for a new engine and install from the dealer.

    If the mechanic wants $3G. That's a LOT of money. I'd defenitely look in to a new engine. Specially since head gaskets aren't usually worth repairing due to the simple fact that engine components don't like water in the oil. You might get the motor fixed and running but it probably won't last.

    Just had the car towed home..stars and runs, but still bubbling back to coolant reservoir. Leaning toward finding an entire engine and not messing around with the head gasket. Any recommendations for shop manuals or videos so I don't screw something up?? Couldn't find much on YouTube for this engine.

    I just replaced the head gasket on a 2014 1.4. The head gasket is relatively easy to get to and straight forward

    Do a pressure check on each cylinder first to determine where the leak is. For each cylinder turn the crank to top dead center and put an air pressure line with 120 pounds of air on that spark plug hole to find out which area of the head gasket is leaking. Then pull the head and take a close look at the head gasket at that cylinder location. Take a close look at the cylinder for leaks and have the head pressure checked for leaks and flatness. Have it planed if not flat. Check the block for flatness. If everything is Ok, then just replace the head gasket. Not much money to do that and not difficult to do. Replacing the engine will probably cost more than the car is worth.
