Trying to figure out if the thermostat is dead. Thanks.

I own a shop, and think this; It really depends on what the outside temperature is. On a cold day it may take from 20-30 minutes to bring the engine up to temperature, but on a warm day it may reach operating temperature in as little as 10 minutes. Thermostats are funny, they can stick open or closed, and be difficult to determine if they are any good or not. The first thing to look at is; The coolant level being up to full, as this can cause you to not have heat, or the engine to not get hot enough. Once it is full, let the engine idle for about 20 minutes or until the fan comes on. If the fan hasn't come on in that length of time, you might have other problems with the temperature sensor, fan motor, relay, fuse, or the thermostat being stuck. Thermostats are pretty cheap, and are the first thing to suspect when one doesn't act like it should. When the engine is up to temperature the top radiator hose will be real firm, and hot to the touch. If its not, then make sure you have a good radiator cap, and have the system pressure tested.
Glad to help out, Good luck!!!

Had this same problem with my 95 and a new thermostat fixed it but after a bit of a go-round because the first thermostat didn't work right. Looked ok in the hot water, The shop said, "I guess we better get the thermostat sold by Nissan.". That second one worked fine.No reason the first one shouldn't have worked except that some component makers have better quality control than others.

The normal operating temperature will be determined by the ambient temperature, the efficiency of your cooling system, and the heat range of your thermostat.
Summertime hot weather tends to allow more engine heat.
Coolant fans, AC, radiator size, H2O pump, hose leaks and heater can all effect operating temperatures.

As in the last answer. Drive over and get you a thermostat and metal gasket Dealer has them. So far I don't know any aftermarket places to get one.
