Ford contour troubles

[sean210]

I just bought a 1998 Ford Contour w/ the 2.5 DOHC, for my preggo girlfriend
and on our way home it started to over heat, And the temp gauge was stuck way past hot. The guys said it sat for a while. so I figured the thermostat was stuck. Went to replace it and there wasnt one in the housing.
So I put the new one in and replaced the broken coolant temp sensor.
The gauge works now but the car heats up really quick. Then stays in the
normal area until you increase the rpm's a little bit. Then the gauge
starts to rise to hot. Theres no oil in the coolant, no coolant in the oil,
and it doesnt smoke. So theres no signs of a BHG.

Do any one know why it would constantly over heat

Anyone?

Bad waterpump? Clogged radiator?

Do the normal BHG tests anyway, if nothing else just for peace of mind.

My old contour did the same thing, it was a clogged cat. Though this may be a little different.

I never heard of a clogged cat causeing it to overheat,
but my auto teacher did say that the weirdest thing you thing of
happing to a car can happen.

It goes into the shop on monday so hopfully it is
something very simple and cheap.
