I'm gonna replace the coolant on my 89 MCI102C3. Any advise.
What's the best way to drain it
What's the mixture going back in, 50/50?
Any preference on coolant brand
Most Detroit dealers will have the best price anyway so just buy their Power Cool brand I just purchased 4 cases of straight antifreeze at Williams for $12.99 a gal check your local DDD ? what engine. Detroit Fluid Specs 93K217 you will find most approved antifreeze's listed there
Hi Viking, The red antifreeze, you don't add water, lvmci...
