How's Your Antifreeze?

[DRC458]

just don't mix the old silica based (green) coolant with the new extended life OAT (pink or orange) coolants otherwise your radiator coolant will turn into a slushie.

Now you tell me.

I drained the coolant out of one motor. The other is parked in my garage so it doesn't get as cold outdoors.

It is a great reminder! Thank you!

New Green Deal supporters should go top of with clear water as it is the cleanest on the environment.

Drain and add to the radiator doesn't replace the coolant in the block until the engine runs long enough to open the thermostat though. So you could have a radiator good to -30 but a block that still has -5 coolant correct?

Engine block heater will solve the problem, not that anyone in this part of the country has one.

I would think so.

I drained the coolant (water) my outboard motor.

Fire it up and run it a few minutes. There's a bypass hole so the coolant can get through in the t-stat. Some motors even have a bypass hose for when the t-stat doesn't.

Thank you.
I found one of my vehicles needing attention.

Tis why I have enjoyed Diesel fueled trucks. Battery, oil and coolant heaters.

And read on VVKB Diesel Truck heaters. They are superb!
