-08 gt mitä jäähdytin nestettä

[ToniH]

Motorcraftin sivuilla oli puteleita, joilla palautetaan joihinkin tiettyihin jäähdytysnesteesiin korroosionesto-ominaisuudet niiden kuluttua käytössä. Tämä lienee oleellista joissain raskaan kaluston flleet-tason ratkaisuissa, joissa nesteitä ei taloudellisesti kannata uusia samaan tahtiin kuin henkilöautoihin.

Silikaatti on estämässä syöpymistä, mutta on ilmeisesti ympäristölle haitallinen tms. miksi sitä ei enää ole pakkasnesteissä. Mutta silti se on suojaamassa, esim VAG piilottaa silikaatin paisuntasäiliön lokeroon josta se liukenee pakkasnesteeseen ja kestää koko auton iän (huom VAG:n suunnitteleman iän) Siksi suomessa esim. säiliö pitäisi joskus uusia.
Usa-Fordilta on huoltotiedote modulaarikoneeseen jossa kerrotaan että nesteessä pitää olla silikaattia. Olen nämä faktat joskus etsinyt, voi olla vanhoissa viesteissä.

Tässä se tiedotteen sisältö:
Ford does not have performance data for the multitude of
engine coolants available in the
aftermarket and therefore cannot recommend the use of any
coolant except those approved
by Ford Motor Company.
• Due to the complexity of
cooling systems, no one coolant has been proven to work in
all vehicles.
• "Universal" coolants generally do not contain silicates and
nitrites, both of which are required for Ford vehicles
equipped with Motorcraft®
Premium Gold Engine Coolant. Thus, these "universal"
coolants generally do not meet
Ford's coolant specification
WSS-M97B51-A1.
• Ford vehicles equipped with
Motorcraft® Premium Engine
Coolant, meeting Ford specification ESE-M97B44-A, require
silicates and, in the case of
diesel engines, the use of Motorcraft® Diesel Cooling System Additive, VC-8, which
contains nitrites. Thus, these
"universal" coolants may not
be suitable for use in vehicles
originally equipped with Motorcraft Premium Engine Coolant.

• Based on blind laboratory
ASTM testing performed in
duplicate, two leading
"universal" coolants currently
in the marketplace did not
meet the extended D2809 requirements of Ford's Motorcraft® Premium Gold Engine
Coolant specification, WSSM97B51-A1.
• The "universal" coolants
may not be compatible with Ford's recommended supplemental coolant
additive, Motorcraft® Diesel Cooling System Additive, VC-8.
• Use of non-approved "universal" coolants
may lead to eventual engine damage or failure. Problems caused by use of nonapproved "universal" coolant may not arise
immediately, but may occur over longer
periods of time due to additive compatibility
issues.

• Although the Ford New Vehicle Limited
Warranty is not automatically voided upon
the use of a non-approved coolant in Ford
vehicles, if such use results in damage to the
vehicle or its components, the cost of repairing the damage (and related damage) would
not be covered by the Ford New Vehicle
Limited Warranty.
Q. What may be some of the consequences of using the wrong coolant?
• Reduced corrosion protection of cooling
system components
• Incompatibility with engine gasket materials
• Corrosive attack of aluminum components
• Cylinder wall cavitation and engine block
damage in diesel engines
• Potential water pump issues
Q. What are the primary coolant types
Ford recommends for use in its vehicles?
• Yellow-colored Motorcraft® Premium
Gold Engine Coolant, meeting Ford specification WSS-M97B51-A1
• Green-colored Motorcraft® Premium
Engine Coolant, meeting Ford specification
ESE-M97B44-A
• Orange-colored Motorcraft® Specialty
Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D
• Reference the Service Coolant Usage
Chart for specific vehicle usage information
Q. What are the requirements with regard to using coolant containing a taste
adversant (bittering agent)?
• Currently certain states and localities require that coolant contain a taste adversant
(bittering agent).
• Since additional states and localities are
considering adopting the same or similar
requirements, and in order to reduce complexity and confusion, Ford will soon distribute only bittered coolant in the entire
U.S.
Q. What are the advantages of
"extended-life" Motorcraft® Premium
Gold Engine Coolant versus a conventional coolant such as Motorcraft® Premium Engine Coolant?
• Extended drain (change-out) intervals
• No need for supplemental coolant additives required for diesel engines (except in
the case of the Caterpillar 3126E engine)
Q. What is the interchangeability of Motorcraft® Premium Engine Coolant and
Motorcraft® Premium Gold Engine
Coolant? Can Motorcraft® Premium
Engine Coolant be used to top off a vehicle equipped with Motorcraft Premium
Gold Engine Coolant? Can Motorcraft®
Premium Gold Engine Coolant be used
in vehicles equipped with Motorcraft®
Premium Engine Coolant?
• Ford does not recommend mixing coolants. Green-colored Motorcraft® Premium
Engine Coolant should not be used in vehicles except those originally equipped with it.
• However, based on the results of backward compatibility testing, certain vehicles
originally equipped with Motorcraft® Premium Engine Coolant (reference the Service
Coolant Usage Chart for specific vehicle
usage) can be serviced using the yellowcolored Motorcraft® Premium Gold Engine
Coolant as long as the following conditions
are met:
1. If the green-colored engine coolant is
thoroughly flushed out of the cooling
system and then the system is filledwith
yellow-colored engine coolant, the service maintenance (change-out) intervals
of the yellow-colored engine coolant
can be followed.
2. If the green-colored engine coolant is
not completely flushed out of the cooling system (e.g., yellow-colored engine
coolant is used to top off the system),
then the service maintenance (changeout) intervals of the greencolored engine coolant must be followed.
3. All pre-1999 vehicles, as well as all
model years of Mercury Villager, must
be serviced with the green-colored engine coolant.

Sit taas euro fordeissa käytetään vallan oranssia motorcraft nestettä mikä myös korvaa vanhempien vihreän nesteen. Itse ammatikseni autoja korjaan enkä ole ikinä nähnyt että yksikään moottori olisi sen takia hajonnut että olisi syöpynyt rikki, varsinkaan alumiinimoottoreista. Ongelmahan tulee jos sitä jäähdytysnestettä ei vaihda ollenkaan koska jäähdytys nesteen ph arvo pienenee vanhetessaan happamaksi ja alkaa sen takia aiheuttamaan hapettumista/korroosiota, useilla valmistajilla on kiinteät vaihtovälit mutta esim. Psa merkkien neste testataan huolloissa lakmusliuskolla ja jos ph alle 6.3 niin neste vaihdetaan.
