problem #3

i ve taken my car to get fixed multiple times for overheating and coolant overflow. it seems as if the mechanics don t want to fix the problem they ve done pressure tests etc. put a new water pump on but it s still running hot. the gauge reads 205-210 on an hour drive and the overflow happens rarely but still happens. i ve been reading up on this, now is the gasket the problem that i ve been reading about or should i replace the thermostat. I mean there's a way to get that fan going that stabilizes the temp gauge(but that shouldn't be). Got 1 month left on the warranty. thank you.

Just purchased car. Check engine light was on and temperature gauge was working intermittently. Some brown sludge on oil dip stick. On warm days the temp gauge would work and on cool days it wouldn't. When gauge was working the car would come up to operating temp (200 degrees) after 15 miles of driving. Hooked car up to OBDII tool and trouble code was "engine running too cool." Installed new thermostat and problem solved. Check engine is now off, gauge works 100% of the time and car hits operating temp within a mile or two. Fuel economy is improved. The brown sludge is gone.
