How Much Coolant to Drain???

[krminyl@...]

You know you've drained enough when it stops leaking coolant at the
thermostat.

(Sorry Curt, I couldn't resist).

Thermostats and parts are on order for our 1987 8V92. How much coolant
will need to be drained to lower the coolant level to below the
thermostat housings?

I thought about that when I posted my email. But remember, I have an
A-Hole, down the street that is always looking for reason to call code
enforcement. Just trying to be good in the neighborhood.

Curt,

I caught about 3 gallons and about 1 gallon missed my bucket :-|

There are 2 little 1/4" drain plugs on the "bowls" of the thermostat
housings. I used a funnel with a long hose to catch the coolant in
buckets.

My Bird runs at much lower normal operating temps than before the
thermosat change.

Oil temp was 230, now 210
Coolant was 190, now 175
trans was 230, now 210-220

The thermostats increase in temp over time. 3 years ago the Bird was
displaying temps very close to what they are today, after the
thermostat change.

I do plan to replace the water pump soon, prawly in August. Just
preventative maint ;~]

Jay,

Thank you for that information. I'll have a couple 5 gal. buckets handy.
I'm guessing the 8V will let out more coolant than the 6V.

I'm thinking the same about the water pump. The engine mileage is at 87,000.
