The chances of three separate
thermostats being faulty are extremely remote. We suggest verifying the in-dash temperature gauge using a temporary thermometer in the acura integra radiator. It is possible that in-between thermostat changes, your car lost a small amount of coolant, either externally or internally from the engine which would cause the temperature gauge to fluctuate. |
If by some chance a head gasket has started a leak or if a head has
cracked, it can cause exhaust gas to excape into the coolent system. This will displace the coolent and cause a over heat. It usually will take 20-40 min to do so. I would go to a trusted shop (or 2) and have a combustable leak test performed on the radiator. Lets just hope its a air pocket within the system. But the test should only take 30min tops. If you were in Fort Collins Colorado i would do it for you for free. |
