Coolant

[Modena]

My car has done nearly 50 000 KMs. The coolant was last changed at 30 000. When would it be a good time to change it? Also any particular one for my R33 or any will do?

[Topaz]

I would also like to know how to change/flush coolant (in an R32 GTR though) and what brand of product to use in the system....

Anti-Freeze Anti-Boil??

[hanyou]

me too for 32 gtr...

A mechanic friend of mine recommended about every three years for a coolant change.

Cheers but thats like telling me a car needs an oil change every now and then...

Any specific number of KMs it must travel?

bud - i have put in castrol anti-freeze mixed at 1part to 3 with water. When i take it on monday, im gonna get wayne to put the same in - cos it has to be flushed before the welsh plugs are changed.

Go for the best ones, cos as I found out, the wrong coolant (or lack off) can totally mess up your engine (im sure the idiot who owned the car in japan didnt take care of it as well as he/she shoudl have)

I like to flush and change mine every 6 months. Typically before summer kicks in is a good time!

Anyone else think 'toilet'?

Every 2 years or 40,000 k's, if you use 33% glycol, if you use 50% , 3 years 60,000 km. Dont use more than 70%. Its best to use ready mixed, otherwise use de-mineralised water to mix it with .

Never use the cheap coolant ( it has about 5% glycol ) .

wrxhoon is right,

i have been using nissan coolant for years, its cheap and i have ZERO corrosion issues, its good stuff

Sorry that the images are stuffed I don't know whether to fix them (again) because Prank has said they would fix them forum wide.

Another cool trick if you are not sure if you have the correct type or not enough coolant consentrate in your system is to put your multimeter onto amps, Positive in the COLD coolant (radiator cap) and negative to earth! Under 200 milliamps is OK and anything over 200 milliamps most likely means you have some electrolicess going on = bad

Two metals (cast block, alloy head) together with water have a chemical reaction causing an electric charge which means your inhibitors (glycol) aren't working properly with the compositions of the metals which causes rust and corrosion - only a general rule

Make sure when you flush the system - the thermostat is out and you flush the heater core as well

My coolant (water really) came out Brown when i first did it after importation

Thats cool, I remembered seeing it when it had pictures and I couldnt make sense of it Nothing to do with your pics, it was just the locations on the engine weren't recognisable, must have been in a helluva spot.

When I got home from work that day I also realised I had saved it to my Bookmarks

[Jolinator]

ellie that is not how you check if your coolant is decent, that is how you check if you have stray current going into your cooling system, if you really want to check coolant, get a magic eye, it will tell you ethelyne glycol percentage

couldnt agree more. ive had my whole block heater core flushed 3 times so far and im still gettin chunks...

radiator is awesome though cos i had it rodded out at a radiator joint. it needed the top tank replaced too...

guys, check ur hoses as well. just so u know, theres 2 small coolant hoses that run around the back of the motor block between the firewall and the motor. an absolute prick to fix! i needed to have my gearbox removed to get to them. at least now i have some good pics of my clutch assembely.

maybe for a preventative measure, get all new hoses. just a suggestion

I've heard that you should steer clear of the red coolants. Is there any truth to it?

...something about if you haven't used it in the motor since 0km then you shouldn't go near it? :scratcheshead:

For those that care, I have fixed the images (again... again.. again! urgh!)

I just bought Nulon Ultra Cool concentrated radiator treatment. Actually is this a proper coolant or did I just buy something useless for my Skyline? lol

I also got the Nulon Radiator Flush and Clean.
