Not sure except when they called they said it was “seized”. The sepentine belt was spinning and it was still moving coolant when I drove it over there (watching my OBD Fusion gauge closely… it sat around 185-187 basically the whole time). So I suspect the pump bearings go out and the pulley wobbles and allows coolant to seep out, or somethingSorry to hear about your water pump problem. Where is Ice T when you need him? “You shoulda had Car Shield…” Seriously, what exactly broke on the water pump? I remember a few years back when my mechanic had to replace my broken plastic BMW water pump, he showed it to me and by comparison, he picked up a used LC metal water pump and said “these last twice as long”. So at least you should never have to replace a water pump again. Maybe start saving up for a new head gasket?
I’m not too worried about a head gasket failure. It might happen, and if it does I’ll sort it out at that point, but I’ve no concerns about any overheating, and given I’ve had the radiator done at 76k, the coolant flushed at 110k and the valley plate done at 145k and now the water pump at 161k I feel confident I’m getting plenty of coolant flushing happening in my truck
