hey guys just a few questions regarding coolant change.

i was told black grime substance like mud is common on the lid of the radiator cap if coolant hasn't been changed for a while?

also, after topping new coolant up. do you need to re-top it again after a drive as it seem to suck in more coolant?

yes.
you re check/top it up again.

mocchi:
the bleeder bolt should be where your top radatiator hose goes to on the cylinder head,

cheers destrukshn

wat about the muddy grime substance? or is that oil leak

[destrukshn]

nah no oil leak, if there was oil, you'd know about it!
lol.
i'm quite sure that will be caused by corrosion.
from not chanign your coolant for sooo long, or using the water or so.
it's fine.

noob question but where is the heater temp control lever?

[Riviera]

in your car....?

where u turn the heater up and down, hot and cold

non climate control cars have a sliding or twisting knob...
climate control cars usually buttons or a twisting knob also...



also i know it was like 4 years ago lol, but its not distilled water u mix in...

its De-mineralised Water... you buy it in 5 L bottles at any auto store...

ordinary tap water containing minerals can cause blockage
over time cause minerals in the water cause build ups in
water jackets and such...

also i recommend flushing the radiator and engine block using a hose
just to get rid of any build up possibly flush it backwards...
i know water restrictions... but that doesnt apply to everyone

I heard the OEM honda Coolant is a blue colour i think? i was wondering if my coolant in my car atm is Green and i drain that away, do i just pour the honda OEM blue coolant straight away? or should i stick a garden hose down the radiator and flush it with that?
Also do i need to Disconnect the radiator hose leading to the engine b4 draining it? Thanks.

[Riviera]

essentially you should follow the DIY just when the radiators disconnected maybe...
flush it out other wise its all good, or even ask a qoute on coolant change
pretty sure it cant be too much

[Bludger]

Listen to destrukshn when he talks about having the thermostat open, or else, you wouldn't be flushing ALL the old coolant out.

do we have to change the washer on the drain bolt? Is it the same one we buy for our oil sump plugs?
