I had the same problem with a Nissan Pulsar a long time ago and couldn't figure the problem out until after I had to do an engine rebuild but the previous owner actually used an aftermarket radiator cap. The mechanic that replaced the engine tried a stock radiator cap and there was no overheating issues there after. Its worth checking into because a radiator cap only costs a couple of dollars and take little to no time to check. I hope this works for you.

A car when overheats means two things: (1) Timing may be off including electrical (2) bad head gasket. Chec for code reading with a OBDII reader to be more .
May need a tune up!

When the preform the transmission service they will drain you transmission of its ATF fluid an replace it with new fluid. It is essentially an oil change for your transmission.
Lots of forgein car dealers say no but ive own and service nissan toyota and i dont change the fluid because you never get all the old oil out and then you mix new and old, what we do is called a trany flush done with a bg flush machine and is done every 30,000 miles unless its syntheic trany oil then at 100,000 miles, the flush is done with a cleaner and then a conditioner and removes 100% of the old oil. hope this helps.

You either need a new thermostat or the water pump impeller is worn out,this is if the rad fan is working,if the rad fan is not working then you likely need a coolant sensor or a rad fan relay.the water pump impeller is not a serviceable part ,so of it is worn you will need to replace the pump.

03 Buick Rendezvous Overheating
If the top hose is hot and the bottom is cold, your definitely not getting circulation. You,ve already done alot of work to this vehicle so you have pretty much answered your own question. About the only thing left is the heater core. Of course, I dont want to be the one to tell you it is definitely the heater core because obviously I am not looking at the vehicle. But If i was a betting man, thats where my money would be.

1994 Honda Civic LX\overheating within 2 mile drive
Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

I have a 94 nissan altima that overheats. I
sounds like where the water pump meets the engine has warped or the gasket has been blown. Since the water pump has to come out anyway to fix it then i would suggest replacing the pump. It is 30 to 40 more.
