I drove my car to the dealership for the fact that, my coolent was boiling and making a lound bubbling sound in the radiator. I contacted a tech and this is what he said " its normal for evos to do that, its going to happen when you have a car on steroids." I drive the car maybe 10miles a day. I have never heard such a thing!! In all my years of owning cars i have never had coolent boiling in the radiator and in the over fill tank. Any thoughts and fixes would be great.

might have an air bubble, might wanna try burping the coolant system...

if somehow air got trapped in your radiator, like if you changed the fluid recently and didn't get it quite full, it could spew out some steam until all the air in the radiator is diplaced with liquid. It might take a couple a heat cycles, but it will clear itself up. If you haven't touched the cooling system, and it's still doing it, there could be numerous causes. How many miles on the car, and since the last radiator flush? Could be a bad thermostat, a bad radiator fan, a fouled radiator, or a blown headgasket.

Evos are known for boiling over. Try a turbo timer is you want to cool it down for a minute or two. You may also try a GReddy higher pressure radiator cap.

The car has 5000 miles and i only drive it to work and back. I dont have a turbo timer, but i always wait 10 to 15 seconds before turning the car off. It just started doing this.

try waiting 1-3 minutes depending on how fast you're driving. i would also throw in a bottle of Royal Purple Glacier Ice, or some Redline Water Wetter, couple w/a low temp t-stat to try & keep things a lil cooler...

I had the same problem (blown head gasket)

You need to wait 60-90 seconds at least as written on the back of the visor (at least on the Galant VR-4's).

this is only if u are boosting the car a lot. always let the car run at least 30 seconds b4 u turn the car off no matter what, but it all depends on how u drive how long u should wait to turn off your car.

This sounds like another one.

I talked to the dealership and they infaddicly deny that its the head casket. In the long run, what will be the outcome if the head gasket doesn’t get replaced?

I need to let torque Freaks look at it, just dont have the time.

When the HG blows on this engine combustion gases leak into the water jacket forcing coolant into the jug. You'll see boiling coolant in the plastic bottle and dumping onto the ground.

If this is what you have happening then it is the HG.

^ You hit the nail on the head. Every time i drive it there is a bubbling effect, but not enough of a bubbling effect to have the coolant bubble over.
