Hello I'm new to the nissan forum and I wanted to ask a question. I have a Xterra X 2006. I have been having problem with it warming up. I had the thermostat replace to find out that wasn't the problem. So My husband thinks its the water pump. so my question is when I replace the water pump do I need to replace the timimg belt also.

how many miles do you have on your x

You don't have a timing belt, its a chain and shouldn't need to be replaced any time soon. To check the pump, listen for any squealing from the front of the engine that increases with speed. There should also be a weep hole at the bottom of the pump. If the bearings or seals are going bad that weep hole will have green, flaky stuff running off below. If you see that and hear the squealing, its time to replace the water pump.

Also, check the radiator and make sure that its clear of mud and debris. You can remove your cap (when cool) and let the engine run. If the pump and thermostat are working, you will be able to see waterflow across the top tank when the truck reaches operating temperature.

It will warm much faster while driving. If it is an issue of it not warming quick enough, that is a function of a thermostat that is stuck open, not a water pump. New t/stats can be bad from the manufacturere. It doesn't happen often, but I've seen it happen with brand new Honda parts in a dealership service department.

There is no need to idle to let a modern vehicle warm up. In fact it only takes about 30 seconds before everything is set to where you are ready to go. If you reach operating temperature within a couple of miles you are doing just fine. Anything past 5 miles would indicate a problem.

well it wasn't warming up until I drive off.
Unless you are leaving it sitting there for about 15 mins it won't. It may take even longer than that since it is cold out right now. My X doesn't get to warm/operating temp until about 3 mins after I drive away from the house. Usually starts getting warm after I go up the on-ramp about 3-4 miles from the house.

So just remember it does take a little while to get warm. But if you are driving and the temp goes way down then the t-stat is stuck open. That happened to me one time in my old VW Jetta on the way to Tennessee. Never did it in town, I'm in Sav GA so it stays hot, but when I got up around those slow winding turns driving at like 20-30 up and down hill, my temp stayed pegged at cold as the temp gauge reads. At least the engine was warm enough to keep the heater blowing warm air, lol.

I get and crank my truck up about 5:45 and gets in my car around 6:15 and it wwas warm at all when I pulled off and by the time I get out of my neighborhood my truck is warm Like I stated we changed the thermostat and but found out the one I had in their wasnt bad than I was inform that I need to have the radiator flush. But on my next day going to work I notice the hand was rising to h and than coming back down to the point where it should be and it continues to go up and down. But I have decided to take it back to the dealer to $79.00 to put it on the machine and tell what the problem really is.

The only other possability I can think of, is the thermostat was put in backwards. It happens more than you think.
Also a few years ago, I had to put in three thermostats, before I got one that worked. I guess the manufacturer was having a bad week!
