its a 1.4 i need the coolant for .

I would recommend going to a honda dealer and getting OEM stuff.

How often should we change the coolant.

2/3 years is about average.

The coolant that comes in the mondeo is meant to last the lifetime of the car...

The Coolant in Volkswagen Group cars is meant to last the lifetime of the car. However if you top it up with normal G12 coolant you will void this. The coolant in Volkswagen group cars Is Pink.

Yes in fairness, the quality ones come with instructions; just RTFM as they say.

Castrol Magnatec - sorry but I think you could have picked a better example.

A couple of links that pretty much say coolants fall into 3 categories:
* the original glycol-based “green” antifreeze
* coolants based on organic acid technology (OAT)
* coolants based on hybrid OAT called G-05

The colour is just a dye and nothing more.

Cinio lad your too easy, i knew you'd take the bait, you'd argue with your own shadow!

Cinio is right, you shouldnt give out to him about arguing back, then you go straight ahead and argue back yourself, esp when you are wrong!!! :eek:

I'm not really anorak enough to follow through on this (and partly because i dont fully understand) but as technology in cars is progressing the likes of coolant is becoming more and more engine specific. Its much more in depth at this stage than green, red and blue.

Yep, but initially they used plain water, then they added glycol to lower the freezing temperature for colder places, then added additives to prevent corrosion in aluminium alloys, and more additives for mixed alloys with Fe based alloys in modern engines

I could be wrong, but highly doubt that distilled water would be a better coolant than any maufactured chemical coolant product in todays modern world if freezing and corrosion weren't factors.

You could be wrong alright. The specific heat capacity of water is 4180 J/ Kg K, while ethylene glycol is around 2200 J/kg K. add ethylene glycol or propylene glycol and the mixtures SHC reduces. You lose here and have to upsize the radiator. You gain because your block doesnt crack in winter.

I admit, freezing point and corrosion inhibition are certainly necessary qualities of coolant but its main purpose really is to regulate a running engines temperature.

Yep, from an engineering point of view, a high specific heat capacity will win, but for our climate, it must be suitable for year round use, so the SHC must suffer. There are few fluids as good as water for coolant (unless hydrogen, but.........mehh, na forget hydrogen).

I see Cinio takes a fair auld lash here now and again. But he is often right. Maybe thats why he draws so much fire.

I've never yet seen Cinio spouting BS on an engineering subject.

Jesus this thread has turned into a right old debate!

Thread reminds me to plug the leaky rad in the bangernomics Clio so I don't pop the frost plugs in the winter. It leaks about a litre a week and I've been topping it up with water since the summer.

Radweld?
New radiator?

Mycroft H

I'll chuck some Novastop into it and see how that goes. Failing that new rad

It's the only problem in an otherwise reliable car. Can't complain for 400 squids.

Is it hard to drain all the coolant and replace it with new stuff. Its a 1.4 GOLF I should have said.

What type of VW golf?
You shouldn't need to drain the coolant in a golf if its the coolant that was in the car when it left the VW factory.
Is an easy job if you can easily access the tap at the pipe going into the bottom of the radiator (most VW have a tap if not pull of the hose).

It's a handy enough job. You need to find two 5 gallon drums. Cut one about a third from the bottom to make a tray and pour the used coolant into the other with a funnel. It's a hazardous waste. Don't pour it down a drain.

Pre mix the fresh coolant in a two litre bottle and pour it in very slowly. Make sure your heater is set to hot for the whole job.

It's g12 pink coolant for a MK IV. Just mix it 50 50. You can get it in any Motor factor
