Coolant question for Suzuki Alto VXR (PKDM) and Suzuki Liana (PKDM)

[safe_rider]

I have poured almost 1L of Osaka coolant without diluting in my Suzuki alto vxr 2012, with original coolant fixed by company since purchase (almost 6 yrs).
Now after reading forums I think its not good and I should change it immediately.
I have also Liana and I want to change its coolant too.

Kindly inform, can I use all of the below mentioned famous coolants in both of the cars or is there any prohibition of using these (Aluminum block etc).

1) Toyota
2) ZIC
3) FUCHS
4) Liqui Moley
5) Caltex

And what would be best to use in both of the cars.

Thanks for the reply. I will definitely flush the system before pouring new coolant.
Can I safely use any of the above mentioned coolants?

I am confused between words like HOAT, OAT, Ethylene glycol, aluminum engine assemblies etc. and corroding of engine so are all of the above are safe to use in both Liana and Alto.

Yes. Alto has just completed 65k and I am using OSAKA coolant since date of purchase and it has dropped very little coolant in the past as I have poured just 1 to 2L in it. As it was brand new so working as it is with TS valve, automatic fan..

Liana has a different story as I bought it second hand in February and original engine has been replaced with Kabli one. I think there is no TS valve in it as the temperature needled goes up and down on different gears. Needle goes to half on signals and when I drive it in fourth gear at low rpms then needle goes down from half.
Fan is automatic I guess. I am taking it to mechanic for TS valve check and installation if it is missing.

Any advice which will be most suitable coolant from the list I have mentioned.

Thanks. Caltex coolant is also available on Metro ISD and also easily available on fuel stations.
But I could not find this 3L bottle on LM official PK website.

Liqui Moly Radiator Coolant

I have 3 one litre bottles. Price is Rs. 250 per bottle. SOLD [image] [image] [image]

I will LM I-8 office to check.

Are they better than Toyota coolant as a lot of guys praise Toyota coolant and say its best.
