Rad Flush?

Should I do a rad flush on my 3-year-old Honda with only 48,000kms (30,000
miles) on it, or should I wait until 96,000 Kms? Also, does anyone know of
a good site that shows how to do a rad flush?

Thanks,

Nino

 

From where are you getting your numbers? Do you have the
owner's manual for your 2003 CR-V? I would follow it for (1)
replacement interval; (2) directions on draining and
filling. For your CR-V, all a flush is:

1. Drain old coolant
2. Fill with ordinary tap water; drain; repeat until tap
water comes out clean.
3. Fill with Honda OEM coolant (though some of us here think
the orange Havoline Dexcool is just as good).

Follow the owner's manual's directions for purging the
system of air. It may take over a half hour for the engine
to heat up enough to cause the cooling fan to come on twice.

I see the owner's manual at
https://techinfo.honda.com/rjanisis/logon.asp says your
coolant need not be replaced until 10 years or 120k miles
(192k km) passes (then five years/60k miles).

 

You're so right Elle! In fact, there's a sticker on the inside of my hood
that states that coolant should be changed in 120 months which is 10 years
(12months X 10). I find it hard to believe that coolant will last that
long!

Right, I hear you. Still, I would trust Honda on this.
Especially given the price they charge for their fancy
anti-freeze coolant!

 

aren't you the person that wanted to change the fuel filer after only
48kkm? dude, buy the service manual, then read it. that's much better
use of your time and money than obsessive premature mucking about like
this. or get a hobby.

Listen, I have plenty of hobbies! Secondly, When I took my vehicle into the
dealer for safety recall issues, they gave me a maintained schedule. The
maintenance schedule states: "The Honda West Service Maintenance Schedule is
based on the Manufactures Required Maintenance services and additional
services recommended for the "severe" driving conditions in Alberta, caused
by climate and road conditions."
Then the schedule goes on to list the following service recommendations:
Coolant replacement -3 years; Fuel Filter Replacement -48,000 Kms; Power
steering oil replacement -72, 000 Kms; and on and on it goes. SO IF THE
DEALER LIES TO THE CUSTOMER WITH STUPID OFFICIAL 'MAINTENANCE SCHEDULES'
WHAT IS HE SUPPOSED TO DO? I fortunately use the power of the Internet!
When one pays $35,000 for a new vehicle, I don't want to "muck" about, I
want to do it right!

 

Beamer, again evidently really not wanting to help people

Excellent point, and a good one for the archives.

I just checked the Canadian Honda site's maintenance
schedule, and for your 2003 CR-V, it also says 10 years/192
km. Sometimes there are differences between what's required
in Canada, because it often does demand more "severe" wear
and tear on certain systems.

You are 100% correct to ask for an explanation of the
inconsistency. People need to know that when it comes to
routine maintenance, the dealers often are trying to sell
unnecessary services. This is a great example.

You go ahead and keep asking questions. Anyone discouraging
this should not be spending time on this newsgroup.

 

then buy the factory service manual and read the maintenance
schedules!!! that's not hard is it? coolant doesn't "wear out", it
simply ages, as per the book. your constant bleating with "should i do
this premature work or that premature work" is a total waste of
electrons - spend them on google instead.
