I'm sorely tempted to add in some UV leak detection dye. Then when it leaks again, it'll show up fast.
The Dex-Cool compatible dye is about $10 on Amazon. Might be worth it to diagnose a bum pump or a leaky surge tank.
Is this problem more prevalent in the '12 1.4s, or is it ALL of them, right up to the current '15/'16 Limiteds??
(I ask because I'm looking at a 2012 1.4 RS with ~60K on it.
)
More prevalent on the earlier cars. GM's made many revisions to this water pump design. A pressure test won't indicate a bum pump or soon to be bum pump.
I'd ask if the car is covered by an extended warranty on the water pump. Mine's covered until 10 years/150k miles. It's VIN-specific, so run the VIN at a nearby dealer to check. If it's not, aftermarket pumps are $40-60, depending on the source. It's a DIY-able repair by a decently-equipped DIY'er.
THANKS, will do.
