Temp gauge

2003 PT Cruiser turbo, 57K miles, check engine light on, temp gauge not always moving up to normal temp range, but many times stays at the cold temp range.

Dealer indicated they “check out and scanned and tested 00100 check out and scanned and tested found codes for thermostat B rationality so new stat and housing.” Dealers states the stat and housing should be replaced and the prices scribbled on the internal papers indicate this would be an expensive repair.

Does this sound like the proper action to address my problem? I was wondering if perhaps I only needed to replace the thermostat to correct my problem.

I don’t know about the housing, but the stat sounds legit.

Suggestion: find a reputable independently wned and operated shop. Have them look. Chances are good that they’ll be less costly.
