    Chrysler minivan cooling system pressure

    The dealer wanted $25 for the thermostat and they didn't stock it. Their price for the gasket was $40. Even the guy behind the counter thought it was a unusual price. Picked up a thermostat & gasket at Autozone. Got the cheaper $10 one with one year guaranty. It looks right.

    Chrysler minivan cooling system pressure

    I have a 1984 Corvette, on which, the radiator fan is controlled by a simple temperature switch that switches on at 238 degrees. That's how it works. It turns out that the boiling point of the coolant mix under pressure is like 268.

    Water pump has been replaced by the prevoius owner. I got records & recepts for everything that's been done to it. A lot of stuff was done at the dealer. I'd have to look up when the pump was replaced. It's at 110k miles now

    Chrysler minivan cooling system pressure

    It's not A/C condensate or the radiator fan not working. I just wondered if anybody ever had to actually measure cooling system pressure. It's just something I'd like to fix before taking the van on another road trip. My daily driving is not severe enough for any of this coolant loss to happen.

    Chrysler minivan cooling system pressure

    Just browsing around some discussions here, it seem that some members have some in depth understanding of automotive cooling systems. Here's what I got. I'll get to the problem first and than fill in more detail. It's a 2005 Chrysler Town & Country minivan with the 3.3l motor. I believe the...
