I have 1999 Porsche 996 3.4l engine. Can you mix coolant

Removal

CAUTION: Do not mix Standard (green) Coolant with Extended Life Coolant (orange). If mixing occurs, drain engine cooling system and refill with originally equipped coolant type. If this contamination occurs the service change interval on Extended Life Coolant will be reduced from 6 years/150,000 miles to 3 years/30,000 miles.

1. Partially drain the cooling system.
2. Remove the upper radiator hose.

1. Remove the bolts.

1. Remove the thermostat and gasket.

Installation

1. Follow the removal procedure in reverse order.

Remove all plugd and disable coil pack (for safety) and crank engine.

The pistons on all cyc. will push all gas + coolant out of the engine.


Please use towel /newspaper to protect the engine bay and floor before cracking the engine.
The oil/gas/coolant mix will make the floor.

Either low coolant (usually caused by a leaky coolant tank) or the engine compartment blower is on the fritz.

I wouldn't attempt that. Stick with the fluid that the manufacturer recommends many problems can occur if you put the wrong coolant into the system.

have you checked your engine oil if it looks the same?? If your engine oil is mixed/milky colored, then its your head gasket!!hopefully this helps!!

Time to replace the Thermostat and Radiator Cap, if the cooling system has not been serviced, you may want to replace the coolant with a 50/50 mix water/antifreeze. Make sure it's 50/50, to much antifreeze will gel up and to much water will freeze or boil over. If your not sure how to mix the antifreeze, you can buy the pre mixed.
