That's EXACTLY what's going on with mine!!! I saw the leak spurting out in the same area as described after turning off the engine and yes the flavorful smell of the coolant lingered before and after shut off. Since the waterpump is covered under the 120k warranty, I'd rather have them do it since it's such a hassle from what you've described. I've already made an appointment to have the entire waterpump replaced by Thurs or Fri to resolve any issues. I also made their parts dept. order the gasket ahead of time since they didn't have it in.Originally posted by Tone
Mine did it more right ater I shut off the engine from driving but I could smell coolant for a long time before that.
I also just placed an order for a new timing belt and thermostat from St. Charles Isuzu which should arrive later on the week so they can replace them while they have the engine apart. I verified whether it takes additional labor to replace the thermostat and St. Charles said that it's right in line with the pump so changing the parts won't add any labor charges outside of the warranty coverage.
Thanks again Tone and the rest for your input and advice. I wasn't expecting to see the waterpump go out so soon. Oh well, at least I can get the thermostat and timing belt replaced over and done with at the same time.
