I heard the other day that it isnt necessary or even wise to put water in your engine anymore, just coolant. Is this the case??

 

neat coolant?

 

tidy coolant

 

 

I was always led to believe that coolant froze if it didnt have water added....but I never had the ***** to find out if it didnt so have always added water as well

 

but i though coolant acted as antifreeze aswell so surely it wouldnt freeze?

 

25-50% is what concentration the coolant should be, not 100% for sure.

 

Think you're looking at "4life" here, that stuff is a special coolant mix that goes straight in the engine, no water added, same performance and lasts 10 years. I bought 2x 5 ltrs the other day for £24 - saves buying distilled water to mix with normal coolant/anti freeze.

 

40% coolant to 60% water.
Consider the fact that coolant is corrosive and having neat in your engine will just eat your head gasket.

as above when i get a new bottle of antifreeze i tip half the antifreeze out into a spare empty bottle and then top up both half full bottles with water. job done 50/50 tip it in from the bottle then.

 

Surely All water is corrosive and coolant added to water prevent corrosion occur to whatever your engine material made off.

 

I use neat coolant in mine and did in the previous few cars without any problems. Used to do it years ago when i was racing oval circuit cars.Could never get enough cooling when following other cars closely and water just boiled away to easily. It has a higher boiling point than water hence we never lost so much from boiling when we were really giving them some beans

 

Water as far as im aware is neutral ph so not corrosive.... chemical reaction with iron blocks causes corrosion to occure,not a good idea to run just water alone in alloy blocke either,antifreeze is a corrosion inhibitor ....... 50-50 mix is fine

 

I have allways filled my cars with a 50-50 mix

 

is halfords all engine coolant any good? found an unopned bottle in me garage n thought i may use it but didnt know if its any good

 

Would running "just water" cause the coolant to boil up and prssurise the system, in view of the fact the coolant helps the car from overheating
?

 

There seems to be some confusion as to what coolant is compared to just water..... generally its a mix of water to ethelyne clycol antifreeze in a mix from 25%-50% depending on how cold the car is subjected to in winter conditions,antifreeze is needed to prevent the water from freezing (obviously) and causing severe damage to the engine as it expands (core plugs are designed to pop out to prevent this but not reliable) and to prevent corrosion building up.... race cars/bikes generally are prevented from using antifreeze when on tracks as any spillage can be hazardous to following competitors due to its slippy nature,so water alone will work in the cooling system,but for general road use A/F is a must,so if you have cooling issues with your car its the system itself not the cooling medium thats at fault.... check general items for leaks,thermostat for correct operation and if its pressurizing check the head gaskets.....

 

remember you can buy neat coolant and premixed....

 

The coolant itself is corrosive, hence on the bottle it says "corrosive" and has a little symbol

Tony

 

"Antifreeze corrosion inhibitor composition for aluminum engines"...it has inhibitor that stops corrosion in ally engines...

 

Pour it on your paintwork and leave it, tell me then that it isnt corrosive

Tony

 

FFS Are you trying to protect the painted internals of your engine?

 

Do you know my ex wife?

 

Water is NOT PH nuetral.

 

Please explain for everyones benefit and not just mine.......

No mixing with water, just poor it in.
