Coolant - Ready made or concentrate...?

Howdy Z-Folk,

Just wondering which type you prefer and/or recommend - ready made coolant or concentrate???


I currently use Motul ready made, which is rather expensive. Although I'm somewhat clueless with different coolant types...

Should I stay with Motul?
Is ready made any better, or is it really dependent on brand?
What brands are generally considered the best?
Should I avoid mixing coolants?

Cheers all,

Captain Mark

 

Concentrate is more convenient to carry home.....

after all, ready made is just concentrate with water added. With concentrate you get to choose the percentage of your mix. I always use distilled water in the concentrate.

I was always told NEVER mix coolants, apparently they can cause some really bad chemical reactions.:sick:

As far as brands go I think as long as you stick with a reputable name you can't go to far wrong.

 

Yes you guys are right

Basically a complete fill is ok if you have pulled the motor out and can be assured that the block is clean (no coolant at all). Here we use a concentrate that way we can be assurred that the correct ratio 50-50 with distilled water is the go! Stick with a brand that you have easy access to as some are a little hard to find at times. We use a product called Tectaloy Anti-Freeze Anti-Boil, a lot of coolant manufacturers do this as a sideline,there main line being oils and petrol, I personally prefer to use a specialist coolant manufacturer we use about 1000 litres a year.
hope this helps

I would suggest this one, it's really good

but before you put it in your system you have to get rid off all the old stuff completely

redline water wetter

drops your temp by round 20%, lubricates everything. www.cypherindustries.com.au get details in their product list . best coolant on the market ,costs a bit more, works a lot better. Coventry stock it.

 

Redline water wetter

this product is not a coolant and has nothing to do with corosion protection! This product is a water modifier it actually changes the characteristics of water and without getting into the technical details ,but suffice to say can be used with coolants but is no way a coolant. I have seen water wetter used with some success in cars but also seen it show a car as running hotter(to do with the fact it tends to even out water temperature and depending on where the water temp location is taken can sometimes give the impression of running warmer. Stick with a anti freeze of at least a specific gravity of 1060 and you should be fine

 

I use Castrol concentrate....

...for alloy blocks and mix it 50/50 with distilled water. I use castol as I travel a fair bit in the zed and know that I can find it readily at a lot of servos if I ever need to top it up, which is not often but I have had occasional instances of coolant loss from leaking hoses

 

Same as mine perhaps? >>

Castrol Anti-Freeze Anti-Boil Engine Coolant Concentrate, I use it 50/50 plus a splash of Redline Water Wetter.

 

Redline

have to disagree, water wetter is a coolant, ask anyone thats been within 50 meters of a rally car.it's also the choice of most drag racers . if it cools (round 20degrees) also lubricates pumps and seals,stops aluminum corrosion,It's a coolant!

 

water wetter

Russ you have it all wrong water wetter is used to change the property of water by taking or breaking the surface tension of water to enable it transfer heat. If for one moment you think a 12oz bottle of water wetter would suffice when the manufacturer of your zed states a 50% mix of anti freeze. Not trying to stop you using it but if you don't believe me check out if it meets the nissan oem specs!!:thumbsdown: Oh for the fact of rally cars I have competed at state level and we used it for the abillity to transfer the heat more evenly through engine so as to try to remove engine hotspots. It will mix with coolants!!

 

I have no idea where your come from russ, but>>

it might be a good idea to listen to someone who runs a Radiator Service, and deals with coolants every day of his life.
Spot is one such person, and at this point of time, my money is on his opinion, rather than yours.

Don't place all your faith in what someone else uses, just because they're in some form of Motorsport, I remember Peter Brock and his "Magic Crystals", he placed his reputation on them too, bet he wishes otherwise today.

 

Redline's definition >>>

Redline's Water Wetter page

This would indicate it is a coolant additive, not a coolant in its own right. I do use it.

 

Water wetter part 2

WaterWetter® is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30ºF. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass and bronze systems. Compatible with all antifreezes, including the latest long-life variations.

straight from there own web site!!

 

Mark, if you want some water wetter, I have an unopened

bottle you are welcome to grab. let me know if you are coming to Mike's mini tech day?

 

Sounds like the same stuff

 

Straight from their own site!

If it reduces temp by up to 30f, what does it take in your book, to qualify as a coolant? unlike most other coolants can be used with other rust inhibitors etc,(This is comforting to those folk that just have got to have their water green)it does work in a different way,by improving heat transfer,The people that came up with this amazing product dared to think outside the square! Hey! It works!and works great!

 

Nobody has said this product is no good, but it simply is not

a coolant in real terms. It is an additive which enhances and improves the performance of coolants (which includes water), As stated on their site, it can be used with water(a coolant), in racing engines, and will provide a level of corrosion protection in those engines.
There is no such advice given for everyday, prolonged use in road vehicles. In such conditions it is best used in conjunction with a coolant, other than straight water.

Your comments about people who want their coolant to be green

does little to strengthen your argument, and simply serves to inflame an otherwise inoffensive discussion.
Maybe you need to keep an open mind.:zlove::zlove:

 

Hey Russ your last line

how do you know it works? ps all coolants aren't green infact the chemical ingreediants in coolants have little or no colour and the colour is a way of marketing it

 

Have another look at their site

2.5 times greater thermal conductivity than glycol coolants, "Can be added" It can be used on it's own , but is not an anti-freeze.It is one of the few products on the market that tells you that it can be used in conjunction with other companies products,Dump some in, enjoy.The Nissan handbook does state percentages of coolant required, but it's an old car .this technology was not out there when the 300 hit the road, Time and tech did not stop then.I have a book on airframes published in England, 1917 It goes into the best wood for frames, it mentions that the Germans are experimenting with metal Frames, but it will not work due to being too heavy.Dont get stuck with what dad used to use.Got to move on, check your information make a decision based on what you think is best for your needs, I didn't set out to outrage the gods , this stuff works well for me. Hell, VB is a great lubricant, pour some of that in.

 

VB is another story,

but in my last post my question has not been answered that is "how do you know it works for me"
