Running hot replace therostat and radiator and hoses, and it runs hot after driving for 5 min

check the upper radiator hose, and hard to squeeze. that would be a stuck therostat

sounds like it's time to take it to the shop and change head gasket if head is still good ! every time it gets hot it warps it, prob. need new head too !

i would replace thermostat and also check to see if fan motor is running. Best way to check fan is to turn on the defrost and fan should kick on. flushing radiator would help and also check for leaks in the coolant system. hoses,heater core,waterpump. Hope this help and good luck

If you have no air in the system, cooling fans & water pump are working properly, and you didn't install the thermostat backwards, you could have a head gasket problem. Also, make sure the gauge is reading correctly, and the engine is actually hot & the gauge is not giving you a false reading.
If you installed the thermostat upside down, it will not open to allow coolant to circulate. This 5-10 minute time frame you give points to a water pump or thermostat.
I hope this helps.

the thermostat is in the housing where the top radiator hose connects to the engine !!!!
1. remove the top radiator hose from the housing
2. remove the bolts that hold the housing together ( be careful NOT to break them off )
3. remove the old thermostat
4. remove the old gasket with a suitable scraper & clean both surfaces of the housing with the scraper or sandpaper
5. fit the new thermostat & new gasket
6. put the housing back together & replace the bolts being careful not to over tighten
7.replace top radiator hose & tighten clamp & fill radiator with water
8. start engine & run to reach normal running temperature & check for leaks
hope this helps......cheers.

Get your A/c recharged .....

you might need to add water to your radiator

sounds like you need to replace the therostat

replace the therostat ( most likely )

and the radiator cap

1)check coolant level if low ,check for leaks,examine all hoses for cracks and wear also chek thermostat housing for leaks,if no leaks. 2)when engine is hot use your hand to check temp. of upper hose if hose is cool replace the therostat. also make sure the cooling fan runs when engine gets warm. otherwise bad water pump drive belt or belt not adjusted correctly,ignition timing incorrect,radiator core blocked(flush&fill) of radiator grill dirty, radiator cap not maintaining proper preassure(have it pressure check at a shop) good luck
