Temperature Gauge

[Trac Bob]

Hello -



2001 ST - Automatic



My temperature gauge is hitting the roof. The coolant and resovoir level are good. No leaks are apparent - some smell of anti freeze though. Per the gauge - the engine gets to operating temperature - fffaaassstt! Then it creeps up pretty quickly.



I'm thinking its the water pump ? I had this done about a year ago - not by a Ford dealer.



Any ideas on what could be causing this ?



What should this cost to replace if done at a Ford dealer if it is the water pump ?



Any help would be appreciated



Thanks.

Stuck closed thermostat maybe? Or a blocked radiator?

Does the ST actually run poorly with the higher temperatures? Then I'm with Stonemiser? If not, possibly a bad temperature sensor/sending unit to the gauge on the dash.

I'm not the expert here but it sounds to me like a bad thermostat as stonemiser said.

TRACket Paul also has a good point. If the thermostat has been replaced it could be a bad sensor. Is the coolant (hoses, ect.) real hot when the temp guage tops out?

:lol::lol::lol:

Stonemiser, sorry but the hoses probably going to be around 200 degrees F. at normal temps. Overheating temps are going to 240-250 F. when the gauge is at the topped out. I have some recent experience with it.

No I'm talking about what he says, "engine gets to operating temp fast". I'm wondering if the hoses are warm at this time. If not then it could be just the sensor. I guess I should have been alittle more specific.:lol:

OHHH.
