Is the water circulating? could be the water pump not it leaking water?? A head gasket is around 40.00 but the labor could be anywhere between 600.00-1000.00 depending where you go repair it

My radiator of my Hyundai 1997 model are boiling. what can i do

Check radiator cap for good fitment.
If good..
There are two hoses to and from engine to radiator. Upper should be warmer than lower one as it warms up. Hot coolant leaves motor, goes through radiator comes out cooler k?
Is it circulating when hot? Don't let get to hot though, but verify that thermostat is opening up.
You think it's faulty.? Drain coolant, remove hose that thermostat is behind, remove thermostat and take in the house. Put water in pan like a 2 quart type. Put in one quart water. Look at thermostat. This is how it looks closed. Boil water, 220 is perfect above 212 but not 300...k
Drop in thermostat into boiling water
Let set in there 23 seconds...
Remove with salad tongs..that step is critical...i used a piece of wire once that I tied around it ahead of time but that was to easy .
Look at hot it different? Is it open? No ? Go to ripoff zone and get new one and new radiator cap, and new antifreeze, reassemble in reverse, put in new 50/50 mix.
Drive car, enjoy your repair and the 200 buck you saved yourself. Drive to dairy multiple treats...go to time!!
If this wasn't sufficient to fix, dang, check water pump. Pray it's water pump...good. oh no. . Check oil for anti freeze and vice versa...probably head gasket.. oh no!!!

Van blowing cold air

It has air in the line. let ir idle with the radiator cap off for a little while and the air will work its way out. You may have bigger issues, but I do not think you need to clean heater core because you get heat sometimes. Do you see a lot of bubbles when you take the radiator cap off when running, head gasket if so.. You can take the cap loose while the engine is running, but not after you stop it, it will be to hot. Good luck

I changed the thermostat in my 91 plymouth sundance and my car is still overheating and the reserve tank is spitting out coolant

You change the head gasket

The spitting is cylinder pressure or combustion
gases blowing out coolant

My chevy impala keeps running hot eventhough the radiator and the fluid isn't getting hot. But after running for a short period of time or trying to drive for a short period the car runs hot and c

I would start by checking the fluid to make sure it's at the proper level, Then check to see if the thermostat is opening like it should. If you have good flow and you get heat inside the car but the car still overheats I think I'd be checking for blown head gaskets and head warp.

1996 Honda Passport overheated. Heater started only hot air when moving, then would go cold at stops two days ago. When it overheated today, a lot of steam came out of the radiator cap. I noticed the...

Ususally when the heater blows hot air only when the car is at hight RPM is because low coolant in the system. It sounds like a bad thermostat . In the worst case you need to do a diagnostic check to the head gasket. Because the first thing to get blowen out when the car over heat are the head gasket.

Could be, need to check all hoses as well . if you think thermostat you can pick one up cheap enough and change it out, if left without fixing you could cause much bigger problems such as blown or cracked heads. I'd spend less than $50 and save yourself the major repairs.

Ive put everything new on my 626 and it still runs hot

the engine may have a leaking head gasket, to eliminate this possibility a reputable auto repair shop will use a device that attaches to the radiator cap it has a blue fluid in it that will change to yellow if any combustion gas is present in the cooling system passages indicating a blown head gasket. Try the alumi seal product sometimes that works.
