Could be that,And its easy and cheep to do ( my dad always told me growing up to always start with the easiest and cheapest things first.and work your way up from there.), but when thermostats go bad they either stick open or shut,if it sticks open, that can cause it to run hot because it don't slow the fluid down enough to get cooled down in the radiator before going back to the engine...if it gets stuck shut than that's when you blow a hose because the pressure builds up and cant go anywhere...if the thermostat dont fix it your radiator might be getting clogged,which will cause them to overheat also,so your system might need flushed to remove the gunk....but you are on the right track start with the thermostat and if it still gets hot, then flush your system...good luck. yz-maniac

Might be your thermostat or it could be your water pump....Is it getting hot soon after you start it or does it have to run for a bit???? Check waterpump by leaving your radiator cap off (when the motor is cold), and start your truck. Let it run for a bit and look in the filler neck of your radiator and look to see coolant moving around. Sometimes, also the waterpump will give off a howling sound or will sound rough. Also wouldn't hurt to replace radiator cap.

That appears to be trans fluid mixed with the coolant. There is a trans fluid cooler built into the radiator and it appears to be leaking meaning you need a new radiator. Use some dishwashing soap to flush the system after the repair.

I would start by checking the fluid to make sure it's at the proper level, Then check to see if the thermostat is opening like it should. If you have good flow and you get heat inside the car but the car still overheats I think I'd be checking for blown head gaskets and head warp.

Check the thermostat, if it isn't opening when engine warms up, the coolant in the engine will overheat and make pressure in the cooling system but the fluid in the radiator will still be cold.

I change the thermostat and the heat will no get hot

You may have an air bubble in the system. Try removing the upper radiator hose and see if there is fluid there if not fill radiator with fluid until it starts to leak out at that point and replace hose. Start the engine and let it run until the thermostat opens and add more radiator fluid. Leave the radiator cap off for the entire process.

Runs hot must times not all the time.think i need a intake gasket

I don't believe replacing the intake manifold gasket is going to help with it running hot. Try replacing the Thermostat and if that fails look at your water bump and possibly low radiator fluid.

Cooling fan is on all the time

There are only a couple reasons for the cooling fan running constantly. Either the temperature sensor is faulty or the car is running to hot.
In most cases it's the car running to hot. There are several possible causes for this.

  • Corrosion build up in the radiator and engine water jacket.
  • Incorrect radiator fluid/water ratio.
  • A faulty thermostat.
The first thing that should be done is to drain the radiator and refill it with water and a radiator flush.
A good indication of corrosion in the system will be a brown color to the fluid that was first drained.
Once you have allowed enough time for the flush to do it's job. Drain it and refill with water. Run the engine for 10 more minutes and then drain it again. Now refill it using the correct radiator fluid and water ratio.
If the problem persists the next thing to do is replace the thermostat.
This is relatively simple to do and can be completed in under an hour with basic tools.
The thermostat is located on the engine where the large radiator house is attached. Undo the hose clamp and any bolts holding the thermostat housing on. Once you pull that off you will see the thermostat. Replace it, making sure to install the new one the same way the old one comes off. Now reinstall the housing and house.
If this doesn't take care of the issue you may need to seek a mechanic for help.
I hope this helps.

Top radiator hose is HOT, radiator is steaming

have u replaced the radiator and hoses? Thermostat could also be stuck open. Water pump could also be your issue. with motor cool and of remove radiator cap(cap may be bad as well) top-off fluid and start car check for fluid flow with flashlight. Water pumps typically leak from what is called a weep hole when the shaft seal fails. Yours will be located under the timing cover (drivers side) running of the timing belt.
Hit me up after u have check on these.

1990 Lexus Ls 400. What tempture is my car suppose to run at?

your car should not be near that, it should stay at the middle line or a little under. You need to keep an eye on your radiator fluid level. I just changed the radiator and thermostat in my wifes car. DO NOT DRIVE YOUR CAR IF ITS RUNNING THAT HOT, IT WILL BLOW YOUR MOTOR!!!
