If they are warped they will cause the vehicle to overheat. if youve run it hot at all it could have made the heads warp.

    no not will make the engine run hot if they are warped and then you will lose the head gasket.if you have any white smoke from the tail pipe or water in the oil you are on the way to the head gasket going out on the vehicle. i would bet your heads are warped though

Changed xterra manual automatic transmission , now it's overheating

What's overheating? the engine or the transmission? If the transmission is getting hot, then most likely the cooler lines weren't cleaned. If it is the engine. It's just coincidence. Start with the thermostat.

I have a 2001 nissan xterra 6 cyl I have replaced the thermostat and still its overheating. What is the next step?

I can't believe that your radiator is shot, it's a new truck. How about clogged? How about full of bugs or hay in the front? How about the coolant? Are you running coolant or water? Look for white smoke or steam coming out the exhaust after it warms up. This you don't want to see. I would get it to a radiator shop and have them check it for a blown head gasket. They will be able to tell what's happening.

Block liner crack

Most cracked blocks will put the coolant into the crankcase and you would see a milky colored oil. Thoough it can also crack and allow the engine to burn the coolant. In this case, at the rate you are saying the overheating is occuring, you should easily be able to see white smoke from the exhaust.

More than likely than not the cylinder is pressuring the radiator causing the overheating, you can verify this by removing the radiator cap with the engine cold and placing the palm of your hand where the cap was. Start the engine, within less than a minute you will likely notice pressure building.

This can be caused by blown head gaskets, cracked heads or cracked block. The way to diagnose a cracked head/block is to disassemble it and send it to a machine shop capable of doing a magnaflux on the part.

It sounds like they stood behind thier repair and did the right thing with the second repair.
So your options are to pay to have a second shop diagnose the problem or believe the first and replace the engine and or car.

Sorry about your misfortune.
