    If the coolant is lighter in color than the oil, it is good, If it is darker than the oil, it is not good. Obviously.

    my driving average is 1~1.2K per month.
    So does it means i should change the coolent after 3 years?
    am using Toyota's original anti rust & anti freezing. Price was Rs. 2700/4L.

    Toyota red and pink coolant, caltex (OAT coolants) have a life of 5 years or 250k kms. Green/blue coolants (Glycol based) are to be chaged after 2 years or 40k kms.

    And the two types should never be mixed. If a change of coolant considered, then a *complete* system flush is a must before changing the type of coolant.

    for example if i can find the liqui moly's original coolent (anti rust and anti freezing) then what should be its changing tenor?

    Also some experts says never use 100% pure coolent. Should be mixed with 50% water.
    But some says that it should be utilized purely and without water.
    I think i seriously need some assistance here.

    never use neat coolant as it will have very poor heat transfer capability, always cut with distilled water.

    the water does the cooling job, the glycol formulation does the protection and management of the freeze and boil of the water in the coolant mixture.

    ergo - always use the proper recommended ratio.

    when using a regular OAT, HOAT coolant - replace it every 4 years or 100,000 kms. The toyota red and pink are really good products, the best ive used is BASF glysantin.

    Toyota Indus newer cars manauls (All models of Corolla, Hilux etc.) recommend using Toyota "Super Long Life Coolant." From net search what I found is that there are two types of Toyota Coolants 1. Toyota Long Life (red in colour) 2. Toyota Super Long Life (pink in colour.) Checking with Toyota dealerships in Lahore, Multan, Rawalpindi and Islamabad, the coolant which they have available with them is "Toyota Long Life (red colour) only. According to looking on prices on eBay Toyota Long Life Coolant is more expensive than Toyota Super Long Life whereas Toyota Super Long Life has a longer life as well. I am really in a fix since these Toyota dealers are apparently ripping off the customers by offering only Toyota Long Life Coolant (red coolant which is more expensive, has less life and is actually meant for older cars with iron engine blocks. And if mixed in radiators which were originally filled with pink coolant probably destroys its serviceable life also.)

    OMG !! yes right. Its Toyota Long Life Coolant only. Its really new information.
    Good work brother. So does it means that Toyota's SUPER LONG LIFE Coolant is NOT AVAILABLE in Pak.?
    And what Toyota is feeding to all the clients is, its Toyota Long life Coolant (Red color, they poured the same in my car too. Rs. 2700/4L bottle) which is actually not recommended or maybe their obsolete item!!

    If this is true, then Toyota need to be sued very hard in the court for this unwise act.
    Once again appreciate your working in this regard and me also checking through different sites about it.

    Yes brother you are right. They apparently did the same with my car also. I will not name the dealership. In my car only the coolant level in the reservoir was low. First they didn't have the "loose coolant" available with them which forced me to buy the 1 gallon packaging which costed me about Rs. 3,000. Only about half a liter was used. I still have the remaining coolant with me which is just useless for me. And you can understand my feelings when I later learnt that this was apparently not the "right coolant" for may car as well. I should have only added the plain water.
