Nissan Patrol 4x4 (Africa)

Anybody replaced their "normal" coolant with this stuff??

Was watching discovery channel - I think - re-doing an engine and then replacing the normal coolant (which contains water) with a waterless coolant.

Firstly no water = no rust
Secondly boiling point is no longer 100 degrees celcius but something like 180.

Guy let the motor get up to working temperature and then took the radiator cap of while the motor was running no steam and nothing pooring out

See that Silverton radiators stock it as - Evans High Performance Coolants.

Opinions??????

So your engine is going to cook before you are aware off it ?? or am I just plain stupid

Shalom

As I understood it with "current" coolant it will cook at 100 (because of the water)with waterless coolent at only 180 wich is way beyond what your engine opperates, so it should NOT cook at all - ever basically.

Also their is no rust in your cooling system, that nice ugly brown water.

Aperantly one should flush and replave your coolant every two years as well and with this waterless coolant - not necesarry to replace.

I have been using volo coolant in my patrol for a while ....reasons being that when it has water inside it rust the cast ion in the block and walsh plugs take strain .....the rust gets stuck in radiator channels and is abrasive to waterpumps ect ....the other thing is that this coolant is desigend for stationary engines like gen sets ect it takes the heat out of the block and gives it to the air that moves past the radiator so the better the conductivity the better the cooling . Found that the aircon also works better with this becouse car is running cooler when working hard in soft sand ......to get back to water or no water ......no rust is better less wear on engine and parts , the thearmal conductivity of the waterless stuff is mutch better to better heat exthange between motor and radiator the working temps of enginge stays the same so the tipe of coolant being water or waterless doesn't change that . Becouse the radiator is under pressure I think water boiling point moves up to 110 or round oubout but it then changes to steam witch doesn't work becouse the car thas a water pump not n steam one,and the expansoin is not good for the system .....the other reason that it makes sense to me is that my patrol stands for long times some time for 2 months without starting and it keeps the corrosion to a min

So it does seem the better way to go.

Where did ypou obtain and more or less what cost is one looking at?

I don't know too much about this stuff, but one of the concerns I have is that some of the cheaper antifreeze/coolants have a high amount of hydrochloric acid, which is supposed to clean the block, pipes, head and radiator, but high acid will also eat your block away !!!!

I guess the Brand name waterless coolants will not do this type of thing.... but good to check

Siverton Radiators are the agents.

I would check it out very carefully before using this - see below something I found on another forum about this- it says the thermal capacity is less than that of water - not good!

Very much a mixed bag, the lifetime product has a lower thermal capacity than water based coolant. This means the average temperature will be higher. For the NA lotus owners, this is a small penalty. For supercharged owners, who are concerned about higher temps and heat soaking, perhaps not such a good thing. If your coolant temp is higher, your block is hotter, conducting heat to the intake manifold. The serious plusses are reduced corrosion, steam bubbles not forming in the water jackets, which reduce the risk of warpage at extreme temperatures (when overheated) and a long life for the coolant. As a note: the evens cooling website must be quite ashamed of their product's thermal capacity; they do not post their products thermal capacity. Keep in mind, water and anti-freeze are a tough act to follow, when it comes to cooling capacity. The evenscooling website sells higher flow waterpumps for corvette LS engines, this is likely to compensate for the lower thermal capacity of the coolant. It is also a back-door admission there may be a problem when the standard pump is used.

So what will happen if one only uses "normal" coolent and do not ad any water?

The way I understand it.... your ratio of chemicals will be out of balance. Remember there is a certain amount of acid in the coolant to clean the system.... too much acid will be like " pacman " eating your block, waterpump and any other metal
