YES.. Thermostats are Important!

Complaint; "I have no heat inside my Dodge Grand Caravan. Can you tell me why and fix it?" Why sure I thought; time for the space age tools! Using my laserguided thermal temp gun I was able to deduce that the vehicle no longer had a thermostat. I would find that the thermostat had fallen apart and was now spread out deep within the upper intake manifold. Using my borescope, with grappler attachment I searched the inside of this vehicles lower intake manifold and retrieved 90% of all the thermostats components.

Now the fun begins.

The thermostat assembly in this vehicle was used in two model years, and that's 10 years ago. If I wait another four days I can get another housing. NAH! I decided to reuse the outlet housing, and it was no big deal. By grinding the stakes away I was now ready to install a new thermostat. Only thing left to do is align the thermostat and stake it in place.

These are the parts I finished out of that Dodge Grand Caravan. Yes it needed new antifreeze, and the fluid state might have caused the thermostat to fall apart, or was it simply poor engineering.

Can you recall the last time your thermostat was replaced? I know that IT HAS A PROFOUND EFFECT ON FUEL MILEAGE, but I can't remember the last time it was changed.
