I have a 2012 SHO that is a touch over 100k miles and it has started leaking coolant. It's become fairly aggressive leak and I suspect it may be a water pump (since I've read that is a common cause at this point in my SHOs age).
I have had the cold start rattle (not too bad) since I bought the car in 2020, so obviously I would get both done at the same time.
My question here is two-fold:
1. What is the best way to diagnose the source of the coolant leak? I heard something about a weep hole by the alternator?
2. Can anyone recommend a shop in the Seattle Metro for a waterpump and timing chain replacement? I just moved here from Colorado
