My sons radiator hose busted. It has been replaced and refilled with antifreeze. Runs fine, still burning off antifreeze that got onto the motor. The temperature is running good but the "low coolant" light is still on??

raditor cap bad pressure test the system look for leaks

Use a garden hose and flush your cooling system (specifically the heater core) to clear out any blockage or buildup. Once the water comes out clear put the hoses back on and refill the radiator and overflow tank with 50/50 Antifreeze and see if you have heat. If not the next thing to check/replace is the heater core itself.

Refill with proper coolant and regular hose water, following manufacturer or product recommendations.

Go bk to the mechanic and tell him to redo his mistake

Replace the hose that burst and refill with coolant. If the motor shut down almost immediately then the cpu may have shut down the system to save the motor. Use a code reader to read for faults and also to reset the cpu.

You just blew a hose. Let it cool down, locate leak and replace that hose & refill w/ 50-50 mix of coolant(antifreeze) and water.

Not “thermastate,” “thermostat.”

Put a bucket under it, and open the radiator drain valve.
Find the upper radiator hose.
Follow it to the engine
That which it is pushed onto is the thermostat housing.
Unclamp the upper radiator hose at the engine.
Pull it off of the thermostat housing
Remove the bolts holding the thermostat housing to the engine, & remove it
Clean the gasket surface on the engine, and on the thermostat housing
place the new thermostat in position. If the thermostat is vertical, I put a liece of dental floss or sewing thread through it, thered them out the radiator hose hole, and hold both ends to keep it in position. The copper button goes on the engine side, leaving those supporting arms to wrap the thread through.
With the thermostat in position, and the gasket in position, replace and tighten the bolts to attach the thermostat housing to the engine.
Remove the thread if you had to use some.
Push the radiator hose onto the thermostat housing.
Tighten the hose clamp
Refill wit coolant. If the coolant in the bucket is clean, use that. If not, refill with fresh coolant, using the proper mix of water and antifreeze. (Yes, you need anti-freeze in the summer. It raises the boiling point, reducing the risk of a boilover.)

Your cooking the oil in the engine ( getting to hot/possible oil leak on top of engine). Check the front of the radiator for anything that will cause air not pass through the radiator.If you find any bugs/trash/or a build-up dust or dirt clean it out. Next check to see if the radiator and coolant recovery jug has any antifreeze in it. If not refill each to proper levels with a 50/50 mix antifreeze. Then if all is good run the car in the morning and as it is worming up put your hand on the upper radiator hose to feel if it is hot or cold. If the hose is hot and you can feel the antifreeze moving through the hose then the pump is working correctly. If not and the hose feels luke warm with no movement of fluid then the thermostat is stuck closed and will need to be replaced. Also you need to replace the engine coolant temperature sensor (ect) on engine. Hope this will help you.

Hi there.
Not all radiators have drain plugs as stated in the books but all you need to do is to take off the bottom hose from the radiator and let out all the contents ,,but it wont compleatly drain the engine of water,, but if your going to refill with Antifreeze then just add extra strenth antifreeze
and check all hose clips for tightness and turn on the heater to hot when draining water from radiator, and top up antifreeze when refilled
after running for 12 minutes. RON

Check you coolant resevoir. The low coolant switch is located in the resevoir so if it is low on coolant there, the light will come on. If it is full, it could be that the switch is stuck due to gunk build up in the resevoir. Hope this helps you out
