Why 2000 Chevy Astro van heater will not give heat and dashboard temp gauge always stays on the very cold side?

You've got a clogged heater core. It's by passing the coils, and no heated fluid is getting into the system. First get a quality thermostat(Robert Shaw)usually @ Advance Auto. Then have your system back flushed. If that doesn't do it, replace the heater core. It is an expensive job($450-700). If you want to try it, it will take some time and lots of hard work. A Haynes Manual should help. Good Luck! BMannino

You can find the block heater cord behind the grill of your 2001 Chevy Astro. The cord will be on the drivers side of the grill.
