Always use Type D Coolant...!

[Bluebeard]

If you don’t and you fill your 172/182 with generic red coolant, it reacts badly with the OE Type D.... 🤦‍♂️

 

[Krarl]

People that don't use Type-D are the people you don't want to buy a car from. It's £16, hardly a bank breaker 😂

 

[Sash]

This reminds me... I need to flush the megane out and refill with type d.
Had to use red in an emergency before I changed the radiator.

 

[Clio_fool]

This reminds me, I've never looked at the coolant in my Clio. Only had it 4 years though 🤣.

Just bought coolant from the Renault dealer, and I got something else. They had it in bulk, and it was mixable with type D.

If its the Yellow stuff then that's the newer Renault/Dacia/Michelin gear

And unless they sold you a bottle of water I wouldn't mix it mate 😂

It's blue. 😉 And I've drained the system, and changed the radiator for a new one. There might be some old fluid left behind in the system, but it can't be much. I have to change the cambelt in a year or so, I will check the waterpump at that time. 😉

Weird, why didn't they have Green glycerol stuff? That's all Renault usually use 😂

How much did you pay for the blue and how many litres?

I haven't got a clue. 😁

I paid 30 something Euro's for 7 litres, but the warehouse guy gave me 8 litres.

 

[Ol’ Tarby]

Euros sell one that is apparently mixable with any type of coolant. It's clear and about 6 quid a litre I think

 

[Martin.]

Always had halfords red OAT in mine. Never had any issues and no build up of scum.

Had mine 7 and it's never been changed

I think OAT eats yellow metals in the system (if there are any).

 

[Alastair.]

For the price of the genuine stuff its mental to put anything else in.

Sounds like a bottle of San Pellegrino tbh.

Sure it's not tap water/snake oil ? 🤣

 

[Ol’ Tarby]

Probably

Yea it does, usually found in older cars.

Is Type-D coolant not OAT type?

 

[Martin.]

If no yellow metals in the Clios then no reason why red OAT would ever be an issue then.

Unless you're mixing it with type D without doing a flush maybe.

 

[DrR]

Lol sounds about right, Clio’s liking a bit of the old D, just like their drivers.

Is there anything wrong with the yellow coolant?
A local Renault shop sold me the stuff when i changed the radiator 6months ago.

Yeah it doesn't mix with other stuff that isn't yellow. Yellow is just new stuff that's synthetic and green is stuff that's 80 years old and is just a pure chemical

It's sort of like semi and full synthetic oils. You dont mix them unless you're a proper gypo

 

[chris blue]

I use Prestone coolant which has a good temperature range, and mixes with anything you've got

Worked well for me the last 3 years- 172 Phase 1.

 

[JayD]

Red coolant is fine. My 172 had red in when I got it at 6 years old on 42k miles. I didn't realise it was the wrong coolant so always used red. 112k later and it was fine, although the original radiator decided to leak just as I put it up for sale. Still I think that can be attributed to it being 15 years old and having covered 112k. I never had any temperature issues.

 

[MonkeyKnifeFight]

Water is fine!

 

[CTR]

What do you think about Evans waterless coolant?

 

[Bluebeard]

What do you think about Evans waterless coolant?

My mate has been running it in his track car for about 3/4 years and it seems brilliant. Can open the lid of the expansion bottle after 30 minutes on track and it’s nowhere near as hot as normal coolant.

 

[MarcB]

On all my cars I will only use the OE Stuff from dealers regardless if its Ford, Renault, BMW or Vw.

With the 2 Clio's when its Belt time on the cars they get water pumps regardless and every couple of years with a coolant change its a full flush and then Type D put in.

 

[1985michael182]

You sure that build up of crap isnt something like radseal?

 

[Brigsy]

Type d is dirt cheap, no idea why somebody would substitute the cheap red cooIant for it. I know somebody who refilled their megane with red coolant without flushing the type d out properly and it blocked the heater matrix.

 

[1985michael182]

So it's a chemical reaction basically between the Dtype and cheap red.

 

[White16valver]

Water is fine!

With no rust inhibitors and no freeze protection?

 

[Bluebeard]

Yes.
Using a different coolant is fine I’m sure, but I’d only do it if I’d flushed out every last bit of the OE stuff first. Or, save the hassle and just stick to Type D as it makes life much simpler.

 

[1985michael182]

Anyone tried de
Ironised water ir distilled?

Isn't it banned on some tracks because it's flammable?

 

[Bluebeard]

No idea! Lol

 

[JamesBryan]

I think most are if you heat them hot enough.

 

[R3k1355]

No idea! Lol

Quick Google shows loads of Forums all saying the same thing.

Yet not a single thing from an actual racetrack or a motorsport governing body?

 

[Krarl]

Yeah type D is chemical based and goes up in a lovely whooof

Dont ask me how I know. Just use your imagination when you think of "drain pan + welding slag"
