Re:


Thanks Ben,

If I understood you correctly, flushing with water results in 4L still being stuck in the engine? There must be a drain spot on the block if that is the case.

I want to make sure it is completley flushed as I have no idea what the previous owner has done (nor did he).

Yep there is a drain block plug but it is in a VERY annoying spot - it's on the back of the engine near the knock sensor behind cylinder #1. If you can get under the car on stands it might be easier to reach but very hard from the top. Manual says to apply fresh grey silicone onto the plug when re-installing. Plus you will have to drain the heater core and heater hoses if you are trying to drain it all out you will not get it all.

Should be about 1-2L in the block. Flush with water a few times - drain, fill, drain, fill, run the engine up to temp, let it cool, drain, fill etc until no traces of green dye are seen. You can also remove the top and bottom thermostats and flush the system & engine with a hose from the top radiator hose, reinstall the thermostats when done, you could renew the two thermostat housing gaskets while in there, they are about $5 each from nissan (or replace the thermostats as well).

Depending on the K's of the vehicle you might want to replace the water pump while doing the coolant flush, an aftermarket pump is less than $100. PM me and i can send you the relevant procedure from the service manual if you want

thanks emoticon The owner did give me a manual, but I haven't looked at it as yet.

I was considering replacing the [sign in to see URL]'ll see what they are worth when I pick up the coolant.

Re:


Nissan ones will be a little pricey but quite well made, I used dayco thermostats when i did mine which were about $40 for both of them (yes two thermostats, there are two different temperature zones in the engine...). Nissan will have some issues finding the second one's housing gasket as they call it a water control valve or something like that

Re: Blue Coolants


Hi all,
I have a T30 II (2004) that I've noticed a very slight buildup of scale/deposits when looking in through the radiator cap. Got the vehicle second hand from a Toyota dealership 3 years ago and it was filled with a green coolant (not sure if it is genuine Nissan, but i would think it would be Japanese compatible at least).

Anyways, I figured its probably time to look at flushing and replacing coolant just for peace of mind.

I live in remote WA, so access to Nissan coolant is limited, so I am thinking of using something like Penrite's Blue 7 year/450,000 km coolant (probably the best i can get here). Some facts about this coolant are:
[sign in to see URL] (page 5)
- Spec complies with Nissan NES M5059 Specification. It is an Organic Type A (also compatible with Toyota Long Life spec)
- Phosphate, amine, borate, nitrate and silicate free.
- Compatible with all plastic and rubbers and seals
- Gylcol content is similar to Nissan's i think (1074g/L)
- Instead of phosphate, uses denatonium benzoate (10mg/kg) as corrosion inhibitor

Jap spec coolants contain phosphates but no silicates. I figured phosphate free could be a good thing in my case since i will be flushing with hard water and final filling with distilled, so there will be some residual hardness left over (distilled is super expensive here). Bottle says compatible with Nissan, Toyota, Subaru etc in addition to a bunch of European makes. But it also says suitable for use where blue coloured coolant is originally specified.

Reckon it's safe? Is it just an age thing (green = old, blue = newer, thats it)? Could using a blue where green is originally specified based on (from what i can tell) compatible formulations be okay? Guy at Repco reckoned it would be fine but not sure how much i should take his word haha.

Any coolant gurus here?

Cheers!

Re: Blue Coolants


I understand blue has less stuff in it that hurts sensitive engine bits:
"Silicate, Borate and Phosphate free"

It's the 'Silicate' that is a problem for my Dakar bike's Rotax engine. A lot of people reporting frequent water pump seal failures, and they are all running Green coolant, whereas BMW specify "Silicate Free" which is the BLUE. I am yet to prove that Green coolant contributes to early WP failures in Rotax engines, and I have also installed 'Double Lip Seals' in the WP this time as well, so I can't be certain either way, except if it fails again soon = nothing was 'correct' and it makes no difference.

Re: Coolant


Cheers for the input Wiz

Yes I have heard that coolants with silicates (standard off the shelf green) contributes to silicate dropout and casting sand issues in some vehicles.

Re: Coolant


The only thing to keep in mind regarding coolant is that if there are any engine issues which can be traced to a manufacturing fault then Nissan will not consider any compensation unless genuine coolant has been used in the correct concentration.
