procedure to replace coolant

[ualav8]

what is the best way to dump, refill, and bleed the coolant system on the '00 vmax 700? thanks

to drain;

1-lift the rear of the sled remove seat/bumper cover then rear heat
exhanger bleed bolt.
2-go back to the engine bay and remove the the drain bolt then rad cap.
let drain,when done i like to use a little shop air through the rear exh. bleed hole and blow any remaining out.

to fill and bleed ;

Step 1,

1.remove seat,and bumper cover
2.lift up tail of sled slightly higher than motor
3.remove bleed bolt on rear heat exchanger
4.while slowly adding coolant in the hose,allow the coolant
to drain untill all air bubbles disappear, re-tighten bleed bolt
set sled back down.

Step 2,

1. remove the bleed bolt on top of the thermostat housing
2. add coolant and alow coolant to flow out untill all air bubbles
disappear.
3.tighten bleed bolt, make sure system is full and cap is on.

Step 3,

Start the engine and run @ 2500 to 3000 rpm's till warmed up and
coolant circulates good, check heat exchangers should be warm
to the touch all the way around.

if air is still expected repeat above steps..

how do i remove the seat?

two bolts in back inside the trunk off to each side,then up front there's a few snaps on each side that hold the front,watch for the rear light harness when you remove the seat..unplug it.

coolants of today are better then ever,every 5 years or so i'd say is fine.

What kind of coolant do you recommend? I am over due then. I have never changed mine. (I don't mean to hijack the thread here...)

Use Zerex G-05 it's a Ford & Chrysler coolant(NAPA) very very good stuff, low silicate formula.

use it in all my GM cars trucks/sleds...

Awesome, how many gallons does the average sled take?

 

[daman]

for your sled('99 600sx ) should hold around 4 qt's,premix some up(50/50) then have at it..
