thermostat
my mom has a 96 or 97 ford explorer with the V6 and it runs really cool so in the winter she cant get any heat. My dad and i both suspected the thermostat but their mechanic says it needs some special thermostat that costs around 300 bucks, is he full of it or is this true?
any feedback would appreciated

My Ex had this problem too, and it was the thermostat.
I hope that your parents misunderstood the mechanic. If he said that a thermostat costs $300, he is indeed full of it. The only thing "special" about the thermostat in my '96 with the 4 liter V6 is that it uses an o-ring around the circumference of the disk, instead of a paper gasket. It may have cost $15.
Did their mechanic just buy a new boat? He probably has pretty high payments....

Just replaced mine a couple of weeks ago. It seems that it goes out after 3 years. Not difficult to do, just a little messy draining the radiator. (lower passenger of the radiator, **** faces toward rear)
BTW, it isn't really an O-Ring, more of a o-ring like thing with a grove on the inside radius, at least on mine with a v-6. the ring fits around the thermostat. Usually comes with it in the same box. Make sure the little hole on the thermostat is oriented to the top position. it is for bleading off air, and to keep a little flow going through the thermostat so it can "sense" the temp.

You don't really need to drain the radiator. Remove the cap to relieve any pressure that may be in the system, and take the hose off the Tstat housing. You will lose some coolant, but not as much if you were to drain the radiator. Put the drain pan under the engine to capture what you do lose.

Sounds like the thermostat to me. My 94 Ranger (4.0 V6) seemed to need a new one every two years. Makes a big difference in heat and performance. Just drain out a little coolant and remove the housing. Replace the thermostat and top off the coolant in the rad and the overflow tank. Now your warm....
