Ok, so Bumblebee has thrown a low coolant level warning a couple times this year. For the time being, since I'm not really going anywhere, I just top off the reservoir. It hasn't been dry, just a bit low. Tonight I think I figured out the source is the radiator. I could smell anti-freeze taking the dogs to the park and when I got home I checked it out while it was running. The brace for the radiator was a bit wet with antifreeze and the hoses seemed dry. Before I popped the hood I was expecting it to be the water pump but that looked dry.
It's a 2003, Z71 with 185,000 miles on it. I bought it with 109,000 six years ago and don't know it's prior service history. I've done no coolant system maintenance since I've owned it. I figure I should at least replace all the hoses, including to the heater core, while I'm doing the job. My question is whether I should proactively replace the water pump and thermostat since I don't know if they are original or replacements. All I know is that they have at least 76,000 miles on.
My tendency is to replace things that make sense "While I'm in there" so I don't have to mess around with it later. So my pool is, what you do?
