Default 98 Taurus runs hot - need help

I have a 1998 Taurus with a Duratec engine.
The taurus was running great until it overheated on my son one day on the way to work.
Got it home and chenged the thermostat and the temp stay right in the middle of the gauage as long as the car is just idling.
As soon as I put a load on the engine and back out of the driveway the temp goes up. Can barely make it around the block before the temp gage is in the danger zone. Also, it is blowing cold air out when the heat is on now.

I flushed the entire system and back flushed the heater core but still the same problem.

I am stumped as to what to try next.
Any suggestions?

That's what I'm thinking, water pump, but it doesn't make any noise and it's not leakinh at all. Culd the impeller just be worn?
Also, I flushed the system last September and when I flushed it this time the coolant was still very clean so I'm thinking the radiator is in good shape.

The all-aluminum Duratec didn't have corrosion problems, but early models did have problems with the plastic w/p impeller breaking. That sounds like your descritpion.

^+1 with WJC. The impellers didn't wear thin like on vulcans, but the 98 tecs h2o pump impellers were prone to snap off.

I never had a Vulcan pump rot the impellers off ( I have changed 4 or so),
but i HAVE seen the shaft bushing wear eccentric and cause a water leak
or the impeller scrapping internally on the housing.

I HAVE seen a water pump impeller rust off in the Vulcan...part of the reason mine got so hot when I first bought the car. (picture if you want to see)


Anyways, I have a similar question. Yesterday I drove from Sweetwater to San Angelo and back and on the way to San Angelo I pushed the car up to 90 mph passing someone and it got hot fast. I let it cool off and checked the fluids, all were fine. Is there a 'natural' limit of the 3.0 Vulcans? Also, it ran warmer then normal since then. On the way back to Sweetwater it ran warmer then norm (norm on mine is around the 20mph mark) altho it was pretty chilly outside. Does that have anything to do with it?

P.S. my heater would run hot for a bit but it soon cooled off (during the day) tho during the drive back at night it stayed hot and then warm...ish but cooled off as well (just took longer). Any ideas with this would be nice too.

Sounds like more rustsludge has accumulated and is blocking the radiator and heater cores.

Let me guess, your degass tank was completely brown with gunk when you
changed the water pump? Unfortunately, you may have a head gasket
change on your vulcan in the future. If you look in the bone yard, and good percentage of vulcans there died by head gasket failure and brown
cruded up degass tanks due to lack of coolant changes and maintenance.

I would get a chemical flush done, flush the heater core again, and put
in new coolant and pray. YOU may also want to remove the lower cover below the radiator and flush out the radiator and AC condensor cores
up front with hose and nossel.

You may also confirm that your trannie is truly locking up the TC at high
speeds. A unlocked TC will generate a lot more heat in the cooling system
