Thanks for the feedback!Hi,
I don't work on these so take that into consideration.
But I agree that it could be "localized" overheat taking place.
We have seen several instances here about flow problems in the 90° elbow hoses at the ends of the exhaust manifolds on these engines. See items 7 and 8 in the link below;
In addition to those, there's always the possibility of minerals and debris in other areas of the cooling passages and I have seen cases where a faulty electrical water separator caused an alarm.
Good luck.
Thanks for the advice!Thermostat has nothing to do with "peeing." Typically, if not peeing either the telltale indicator is plugged, or your water pump has totally failed. First, make sure the telltale hose and nipples are clear. Then drop the lower end and thoroughly inspect the water pump. Make sure that the woodruff key the locks the impeller to the drive shaft is in place and has not slipped out of its position. Last summer I had that happen and had to replace the entire drive shaft.
Ordered a water pump. Thanks again!!Unless the water pump is nearly new, replace it - not just the impeller, but the whole thing - it's just about $100 more compared to the impeller and gaskets that come with the impeller kit.
