  Q: How to replace a thermostat in a cooling system on Chrysler Cirrus?

  A: Before you assume that the thermostat is in charge of a problem on an air conditioning system, inspect for coolant level, drive belt tension and temperature gauge operation. When the engine seems to take long before warming up, then the thermostat could be stuck open. Replace it with a new one. If the engine is hot, put your hand on the upper radiator hose to verify this. If this hose feels cold but engine is hot, then probably it happened that the thermostat closed so tightly not allowing any coolant from out of engine to go into radiator. Replace thermostat. Therefore if upper radiator hose is hot as well as there are signs indicating that coolant actually flows around and therefore our thermostat is opened up to some extent we know what to do. In order replace it remove negative battery cable; empty cooling system; trace upper radiator hose end to identify where it fits onto the engine block (thermostat housing); unfasten both clamp (joint) and pipe itself; release clips and remove cover off; get thermostat out of its place; wipe away residues of old gasket's traces and glue (sealer) from these two components in question; fit the gasket back on housing together with a new O-ring by putting (installing) aforementioned component onto "the right" part of car's bodywork as well as installing fasteners' cap over same hole again simultaneously just like by mounting another gasket finally just affixing housing-cover assembly also next tighten up similar joint using fixing tools while refilling cooling system again then turn starter key switch thus making motor start normal temperature test for leakages and adjustment of controlling unit will begin now or other time after all.
