That is NORMAL. The head bolts go stright into the water jackets on all Chevy engines.
The oil has coolant in it. The normal causes are a failed head gasket, a cracked head, or a internally failed oil cooler.
You may have a cracked head or bad head gasket. The car will start to overheat from lack of coolant if you don't check the radiator coolant and refill it, if it's low. You need to get the car repaired or replaced before it breaks down and leaves you stranded .
Most likely you have a leak when the system is pressurized (engine running and at normal operating temperature). A radiator shop will be able to pressure test your coolant system and find the leak. Could also have a cracked engine block, or a hairline crack that expands when the casing gets hot.
my s-10 has a 383 stroker it runs about 190 until i cut it off then it runs about 230 i dont no if this is your problem but mine had to have a fan that ran for about two min after i cut it off.
obviously !
Because the temp gauge is not giving you the temperature of the water/steam in the radiator. You may have a bad head gasket or a cracked head causing the coolant to have that boiling effect.
It weakens the effect of the coolant.
The normal direction of circulation in the coolant system would push the coolant out the thermostat opening.
it could be a plugged radiator ,faulty thermostate,water pump. or over fill of water that's why of spill. The worst case !!! cracked head gasket.!!!
180-220
If it is just water, it is condensation, and nothing to worry about as this is normal when you first start the engine. If however it is coolant you have a serious problem which is more than likely a blown head gasket or cracked head. If the water smells or taste sweet it is coolant, and not plain water.
The 2000 Chevy Corvette normal operating coolant temperature is 195 degrees. You can install thermostats that will allow the coolant temperature to only run at 180 degrees.
