Not frequently,maybe once a month. if the coolant is going down "drasticly",and no visible signs of a leak,then you have a bad head gasket..

2004 nissan sentra heater only blows hot air at 30 mph none when at idle


check your coolant level, it's probably low. if so find the leak to prevent serious engine damage. if coolant level is ok, suspect a thermostat that is stuck in the open position. good luck.

I am getting P0128 obd code for my nissan sentra. how to solve this



Take note of the blurb regarding NISSAN products below


A code P0128 may mean that one or more of the following has happened:

Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:

  • Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat
  • If Nissan vehicle, check for Technical Service Bulletins (TSBs), as the ECM may need to be reprogrammed to correct the P0128 code

Where is the coolant sensor located on a nissan sentra 2001 1.8 engin


I assume you are referring to the coolant temp sensor. as you look at the front pulleys of the engine, its on the right side behind a bracket just above the alternator. See picture below and let me know if you have questions. If you are referring to the coolant level sensor, it would be on the side of the coolant reservoir.

No heat


My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
