My mech seems to think it's done, because I drove it that short little distance (literally <2 miles) to somewhere I could safely stop.
It wasn't knocking or anything so I would like to disagree. It had JUST gotten hot as I was getting to work. I don't know a TON about these engines but I drove my cousin's car with a blown head gasket ~20 miles to a repair shop and it was repairable. So I don't see how 2 miles would kill a younger/ well kept engine.
Of course he thinks it shot, he wants the $$$ to fix it.
As far as the issue goes i think that_guy is on the right track with the water pump.. I know it is new but, new parts DO fail, that's why i don't shop at Autozone with there duracrap parts anymore.
Bottom line is something is preventing a proper flow.. If it be the new water pump, sticky thermostat, or a clog in the radiator i can't say but its something. Also you have the 4.7L, when you did the water pump and added new fluid did you burp the system? IIRC, the 4.7L required a good burping so you may just have large air pockets in the system not allowing coolent to get where it needs therefore creating overheating. Just my
STANDARD PROCEDURE - REFILLING
COOLING SYSTEM 4.7L ENGINE
(1) Tighten the radiator
draincock and the cylinder
block drain plug(s) (if removed).
CAUTION: Failure to purge air from the cooling system
can result in an overheating condition and
severe engine damage.
(2) Remove the cooling system bleed plug from the
radiator upper hose inlet housing. (Fig. 11)Fill system
using a 50/50 mixture of ethylene-glycol antifreeze
and low mineral content water, until coolant begains
coming out of the cooling system bleed hole. Install
the cooling system bleed plug. Fill radiator to top and
install radiator cap
. Add sufficient coolant to the
reserve/overflow tank to raise level to FULL mark.
(3) With heater control unit in the HEAT position,
operate engine with radiator cap in place.
(4) After engine has reached normal operating
temperature, shut engine off and allow it to cool.
When engine is cooling down, coolant will be drawn
into the radiator
from the reserve/overflow tank.
(5) Add coolant to reserve/overflow tank as necessary.
Only add coolant to the reserve/overflow
tank when the engine is cold. Coolant level in a
warm engine will be higher due to thermal
