2007 toyota sienna radiator flush

Asked by Aug 23, 2016 at 10:37 AM about the 2007 Toyota Sienna CE

Question type: Maintenance & Repair

Hello Sir,
Thank you for your immediate reply, I have followed almost same
procedure as you mentioned, I can do one more time
Can you please let me know why radiator became full when added only 3.9
litres of coolant instead of 11 litres as mentioned in Toyota 2007 sienna
manual. Is it really required 11 litres of coolant while flushing or 11 litres
required only when they fill brand new van radiator ?
you mentioned most of the shop using machinewhile draining, Are they
connecting vaccum machine to drain petcoak ?
Thank you
Kotian

Hello kotian,

litrs engine radiator flushing".

They wrote:
"To drain the coolant using the radiator's petcock you generally get less
than half the coolant in the system (about 40-45%). Most shops use a
machine to flush a cooling system so they know they can replace it all with
new coolant in one step. To do the same at home requires draining and
replacing coolant with distilled water in several passes before you can
safely assume all coolant has been flushed. Here are steps for at-home
coolant flush: 1) Drain radiator via petcock. 2) Fill radiator with deionized or
distilled water. 3) Run engine up to temperature until thermostat opens
(with heater on). 4) Let engine cool a few minutes, then carefully open
radiator cap. 5) Drain radiator again. Flushed coolant should be diluted due
to the added water in step 2. Tighten petcock. 6) Allow engine to cool and
go back to step 2. 7) Repeat steps 2 thru 6 three or four cycles. The
drained coolant should be nearly all water by this point. 8) When satisfied
(or just tired of repeating the procedure), add between 3 and 4 quarts of
CONCENTRATED coolant (not the pre-mix stuff) to the radiator. There will
still be 3 qts or so of almost pure distilled water in there from the above
steps. 9) Don't forget to drain and replenish the coolant reservoir as well.
Just be sure to use distilled or deionized water and not tap water, and to
BURP or bleed air from the system when all is said and done."
