2001 Nissan Sentra - heater only works when RPMs are above 3000, like when I'm cruising down the highway at 60mph or more. Only cold air when driving through town or on country roads. Also, coolant not cycling properly between radiator and reserve - when driving home yesterday the engine ran very hot. After shutting the car off I noticed the coolant reservoir was full. I checked later that night and reservoir was back down and radiator was full. Car also leaks some coolant near cap (which doesn't seal as tightly as in other cars I've driven). Any ideas? Thanks!
have the same problem?
