Cougar engine temp...

I am the owner of a 1992 Mercury Cougar LS, with the 3.8 liter v6 engine in it. Recently, I had a slew of overheats which I believe was caused by a bad thermostat. Given the option of paying $7.50 for a thermostat, or $800 for a head gasket, it was a no-brainer.

Unfortunately, I seem to have a new problem, and it's the exact opposite of the old one. With the new thermostat, the car just doesn't seem to warm up! I've driven it for half an hour of city driving, and the temperature still stays far below the norm. Anyone out there have any ideas?

Have your radiator flushed and put another new thermostat in. Do you have heat in the car? Does it move off the Cold end of the gauge? If so, it may be normal temp.

The needle barely budges off the cold end, and the heat is luke warm at best. It's got a brand new thermostat in it now, though. What would the radiator flush do?
