MG TD TF 1500 - Waterless coolant

Hi guys As nothing is too good for our pride and joys I was wondering what people thought of waterless coolant. Yes or No
D Lamb

No. Nothing wrong with water + ethylene glycol based antifreeze, which is much cheaper and a better coolant. Providing you change it at the recommended intervals.

I have to concur with Dave. I have water plus red antifreeze in the TF and there is absolutely no problem with boiling so why go to the expense of waterless coolant. I also believe that you must only top up with waterless fluid, it does not mix with water. I am now a grumpy old man and am anti all modern, expensive, trendy additives.

It mixes perfectly with water because it is fully compatible propylene glycol. However having done so you just have a regular water / antifreeze mix and any advantage that it might have had before has gone (you can't remove the water once added).

Jan. The type of antifreeze that you should be using is usually blue - Antifreeze with Silicate stabiliser. The pink / red stuff is usually the other kind of Antifreeze with OAT type stabiliser - intended for use in modern engines that have lots of Aluminium components. Halfords, for example, have both types.

I use standard antifreeze but add No-rosion...

I use a purple antifreeze from Caterpillar which prevents silicates from clogging up the radiator. A very expensive proposition on heavy equipment and semi trucks. Ask me how I know

I use water and a water pump lubricant in the summer as water is the best for heat transfer.

In the winter,I do use antifreeze, whatever is least expensive at the auto store. Difference is when I change it back to water in the summer, I also do a cleaning of the system.

I have used waterless for the last two years with no overheating problems and haven't had to top it up once.
XPEG blocks are too rare to risk rusting.

Check the archives, this has been discussed numerous times in depth.

Bottom line, the gunk is more viscous; harder for pump to circulate, thus slower; has lower thermal capacity, thus the engine internals are operating at much higher temps, even if the gauge says it is cool.

Just something hyped by snake oil salesmen to take your money.

Guess I should have labeled this "Waterless Coolant Again Again!"

Or as you say Jim read the archives.

My reference to the archives is not to curtail an interesting discussion, it is just to say there's a great deal to read from a few years back... you can get a lot of discussions all at once, rather than just trickling in.

I pressurize TD cooling systems with a radiator neck & pressure cap connected to the over fill drain tube
Glycol & water

We used Caterpillars pre mix in all the Cat engines, I don't remember the part number or even what color it was, but if Cat recommended it for their equipment, it was all we used. Came in 50 gallon drums carried on the grease truck. I never put it in my vehicles, I always used the Green and never had a problem. PJ

Using Cat recommended liquids was a warranty issue, just in case there was a problem later.
