Reviews LAST UPDATED October 8 2019 Entering our 7th season of DRIVE on NBC Sports and with millions of YouTube and Facebook followers Antifreeze and engine coolant are the same product sold in the same packaging and both go into the vehicle s radiator. It looks like it starts at the front of the engine and slides down the oil pan you can see this in the picture the direction it is flowing . The coolant flows from the radiator to the bottom of the overflow tank through the overflow tube. Try a new radiator cap and let us know if it nbsp 2 Apr 2013 So with the car running I opened the radiator cap and the coolant So I just topped it off with the rest of coolant I had left and then went to a gas station to the coolant is just below boiling point or there is a leak somewhere nbsp Coolant antifreeze and radiator fluid all describe the same fluids that are critical to your vehicle 39 s cooling system. Its never had that kind of pressure before. This is easily solved take your radiator cap off as your car is running in a properly working coolant system that is bled the coolant will just flow by not come out bubble out. Add water and coolant or pre diluted coolant as necessary. Same result when i go WOT it blows coolant right out of the cap. However the Fiero is NOT most cars and the the radiator cap is well below most of the coolant level so if you open it most of your coolant will come pouring out. Average repair cost is 980 at 104 550 miles. It s equally important to make sure the coolant is at the correct level is the right color and clear of rust. Caution To avoid being burned do not remove the radiator cap or surge tank cap while the engine is hot. When the cooling fan operates and coolant circulates refill coolant through the radiator cap. This is not something to ignore but it isn t necessarily a difficult problem to fix either. coolant exploded out of radiator cap
