Old post got air pockets in it, burp it like we do all cars.
ask
see list of 17 signs here, (evidence)
http://www.fixkick.com/overheating.html

and all cures.
just for G16 engines
both 8v and 16valve versions.

i bet its cold out.right? February.
Cel lamp out running, if not, spark timingen may be way wrong.
when the read tubes clog then spark is wrong, the rad can overheats due to 2 failures at once. ? even 3.
or cap is no good, or thermostat bad.
you have tons of cold air there moving so the rad would have to be super clogged to fail
thermostats are weak technogly, see netfilx video of tour o that.
and he show why, they go bad 3 to 5 years old.
shorted lived part. so we always assume that it bad.
like car batteries, same deal ,weak tech.

or not burped right
proof?
easy

  1. pump in, all in.
  2. fill it with 50% AF ,right, to top of neck ,side tank 1/2 full.
  3. run (idle) engine until AF exits filler cap hole, kill engin, put on new cap.
  4. drive around block
  5. let cool below 130F or near.
  6. open cap.
  7. is it still full, sure its not, its got air pockets, all do.
  8. fill again, jump to 4.

g16 are not hard to fill
unless shade tree puts therm stat in, with bleed hole forward ,up hill. or upside down.

Dodge neon overheating

I would be thinking radiator or water pump. When the engine is warmed up and the upper hose is hot, feel the lower radiator hose. It should be hot too, just a little cooler than the upper hose. If there is some blockage in the radiator, the lower hose may feel cold or just lukewarm.
Even though the water pump doesn't leak, the impellers may be made of plastic and have considerable wear. That would restrict circulation.
The heater core should not be an issue. Heater cores do not cause overheating even when totally plugged up.

When your daughter rear ended the other car, she could have caused one hose somewhere to get a kink in it. Please follow especially the pipes underneath to check for a kink. It may be a very small hose but it can cause this problem. It did it to my 1990 VW Golf GTI.

It could also be that there was a metal pipe that bent also and water is not circulating properly.

97 Landcruiser. It overheats, and the water does not seem to be circulating. (No pressure or water flow through upper and lower hoses). Is this a water pump? I always thought water pumps leaked and...

Before throwing a waterpump at it, try a thermostat. If that sticks shut you'll get no circulation and overheating. A way to test, pull thermostat and TEMPORARILY run it without thermostat.I stress temporarily and just for test. You should see water circulating through radiator then. If not then you know waterpump is bad.

Engine overheating

Try to flush the system And inspect radiator. When moving the engine is also cooled by air. Make sure the water is circulating trough the manifold and the heater core. You can do this by atching a garden hose to each hose one at a time. You may also want to check the waterpump & thernostat..

Vitara overheat

When driving down highway only, it overheats? When running steady, I take it you mean, sitting idling? If it's only overheating at highway speeds, and all else has been checked out & is o.k., I'd take a close look at rad hoses for soft spots (easy to squeeze) that may be causing hoses to collapse at highway speeds & restricting flow of cooling system. Another thing to try is, turn your heater on high fan & high temperature when it starts to heat up & see if temperature gauge goes down (cooler) at all. If it does, then rad not doing it's job properly.
