I put engine coolant in my car and water but its still overheating do I need to put more water?

Question

i just recently replace the radiator so it couldnt be that

Answer 1

could be the water pump or the thermostat

Answer 2

As long as the water level is visible when you open the radiator cap, you don't need more water. Try opening the cap, then turning the car on first thing in the AM, when it is running, you'll be able to see if there is enough water in there. If that isn't it, you most likely need to replace the thermostat, any Auto Parts store can help you test yours, they are relatively cheap. If it still does it you may have leaks in water hoses, still, then maybe a clutch fan. I wish you the best of luck. Try the thermostat first

Answer 3

There are many reasons for overheating - if the coolant level is OK, but the car still overheats have it properly diagnosed - it could be bad thermostat, water pump, air in the system, radiator fan not working, fan clutch, head gasket, etc. Have the mechanic to perform proper diagnostic - it's fairly easy with good equipment.

Answer 4

Water pump, thermostat, fans, air pocket in the coolant system. Look for coolant coming out the water pump or if it's noisy. Feel the lower and upper radiator hose's and see if their both hot when it over heats if not a thermostat could be stuck.

If it wasn't over heating before the radiator you could have a air pocket some where.

Answer 5

If your not loosing water -check that you havent lost a fan belt that drives the water pump.you can also take the thermostat out and check that it is opening ok by dropping it in boiling water.When the car is stopped,check the engine oil to see if it has turned a milky color--if it has you have a blown head gasket.You can also take the radiator cap off and run the car while watching the water to see if theres any signs off air bubbles in there,-this also is a blown head gasket.Is the water pump pumping water?-you can check this by disconecting the hose(top) and run the car to see if the pump is pumping ok,as sometimes the impellor blades corrode away and they dont pump.Its a process of elimination--just start with the easy things first and hope its not the head.--good luck.

Answer 6

Drain and flush the radiator. Replace the thermostst. Check the water pump.

Answer 7

Make sure thier isnt a leak if the radiator is new you should have tried the thermostat first i also went all out with a new radiator $195.00 and it turened out to be the thermostat $5.00 and get a new gasket for the thermostat $0.96 always start out with the cheap things.

Answer 8

Also make sure there is nothing obstructing the radiator, sometimes leaves or garbage off the street can get sucked up and stuck and block air flow to the radiator.

Answer 9

GO OUT AND START THE CAR AND LET IT GET UP TO OPERATING TEMP AND THEN FEEL THE RADIATOR HOSE COMING FROM THE THERMOSTAT IF THE HOSE IS HOT THEN YOU NEED CHECK THE FAN TO SEE IF IT IS OPERATING LIKE IT SHOULD IF THE HOSE IS NOT HOT AND IT STARTS TO OVERHEAT AGAIN THEN THERE IS A BLOCKAGE WHETHER THE THERMOSTAT IS BAD OR IF THERE IS A BAD HEAD-GASKET BUT I WOULD START WITH THE THERMOSTAT

Answer 10

No you need to first check your thermostat if this is not the problem then check the water pump..in most cases the termostat is the problem but if the problem is neither one of these you may be dealing with a cracked head.

Answer 11

Take the car back to whoever installed the radiator.
You shouldn't have trouble after a mechanic has worked
on the cooling system.
