Hot heat at idle cool when driving

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.

Possible thermostat but more likely fan belt is slipping when idling causing waterpump to slow or even stop spinning. Tighten or replace fan belt that runs over waterpump pulley

Truck is running hot. i got fluid in the radiator. is it time to replace the thermostat?

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

97 Hyundai Lantra. Temp gauge shows engine very hot

If the replacement thermostat is good, and installed properly, then the temp sensor might be bad. I hate to tell you ($$$$$) but waterpump could be bad (more expensive)
