Engine Cooling problem V8 Two Wheel Drive Automatic 49000 miles
Twice coolant temperature gauge has failed to register pass 100F. After approximately 10 minutes driving time, gauge warning light came on and AC quit working. Engine is not overheating. Dealer replaced thermostat after first occurrence. Problem came back few weeks later but self corrected - gauge started working, warning light went out and AC came back on. Gauge readings are erratic at times - between 165 and 210 ( 1/4 mark to 1/2 mark on scale ). Gauge never reads past 220. I have Chevrolet TrailBlazer LS 2008 ( American Version ) having 65000 miles
I am facing problem of dropping of temperature gauge while driving. It comes automatically down after some time during driving. One of the mechanic has replaced temperature sensor but problem still persists. Moreover, once temperature needle goes down to zero during driving, Air conditioning COOLING system also stops working during that period. Sometimes temperature needle works perfectly fine and sometimes drops automatically during driving. Once mechanic RESET from computer, it becomes ok but again same thing happens after few days. I am really so worried. Please help me to resolve this issue.
the dealer have change the coolant temperature sensor, water pump and also the dealer try to fix wires lose but it does not fix the problem. Could it be because of the battery?
Any ideas on problem?
have the same problem?
