Bedankt voor deze posting, een zeeeeer lezenswaardig verhaal
Ik heb dit verhaal dan ook onmiddellijk in m'n "archief" gezet.

Mijn koelvloeistof staat op het minimum mag hier eender welke vloeistof bij gevuld worden van gelijk welk merk, wie weet hier antwoord op. Groetjes, Jules |

Volgens mij is elke koelvloeistof OK... In het uiterste noodgeval kun je zelfs water gebruiken: altijd beter dan géén koelvloeistof. |

Mij werd door de monteurs altijd aangeraden om de roze koelvloeistof te gebruiken. In de roze schijnt een anticorossiemiddel te zijn toegevoegd, hetwelk roestvorming e.d. aan de binnenkant van de motor voorkomt. De blauwe schijnt meer agressief te zijn, is mij verteld en vreet meer aan pakkingen e.d. |

opgepast met het mengen van koelvloeistoffen,deze kunnen een pap veroorzaken!!!! en allerlei verstoppingen veroorzaken |

Water lijkt mij ook niet zo'n goed plan i.v.m. antivries gehalte. |

Gewoon nu water, en dan zo snel mogelijk de goede halen en alles vervangen. Vorst is nog geen probleem en er zit nog antivries genoeg in. De goede is de gele van o.a. Kroonolie. Coolant SP14 |

Aan de specifieke antivries zijn heel veel middelen toegevoegd die corrosie voorkomen. Met name alu koppen zijn daar gevoelig voor, en gisteren stond er een verhaal op XCNL van iemand met een "vastgeroeste" thermostaat. Dat kun je krijgen als je gewoon water gebruikt. Ik zou dus altijd de kvs gebruiken die specifiek is voor dit type auto, niks anders. Ik heb er dan ook wat van staan, als reserve. Dat had ik ooit nodig.... Groet, JW |

Water bijvullen om andere problemen juist te voorkomen en niet alleen water want er zit genoeg goede nog in, maar zoals ik zeg je hebt niks anders op dat moment, maar wel vervangen! Ik heb ook nog 5 liter staan voor nood! is wel het beste. |

Misschien interessant om te lezen... There are three different types of ethylene glycol coolant; 1) IAT ~ Inorganic Acid Technology type coolant ~ this is the traditional "green" formula coolant. This is the stuff that General Motors used until 1996, Chrysler used until 2001, and Ford used until 2002 in its trucks and 2003 in its passenger cars. This is the orginal "green Prestone" we all remember even though Prestone hasn't made this stuff in years! It is available from other manufacturers such as Peak and from NAPA, (their house brand is made by Peak) The green additive package contains phosphate and silicates, and provides good protection for cast iron and aluminum engine parts as well as copper/brass radiators in older vehicles and aluminum radiators in newer vehicles. The corrosion fighting chemicals are fast acting but wear out after two or three years or 36K miles of average use so original "green" IAT type coolants need to be changed out every year or two to minimize the risk of corrosion damage. The problem with "old type" IAT coolants is that the high levels of silicates in them eventually drop out of solution leading to loss of corrosion protection and cooling system problems. 2)OAT ~ Organic Acid Technology type coolant ~ is usually dyed orange to distinguish it from other types of coolant. In 1996 GM began a new extended life coolant call "Dex-Cool". This coolant contains a totally different type of additive package called organic acid technology (OAT). The OAT corrosion inhibitors are slower acting and provide protection over a longer period of time. OAT coolants typically have a service life of up to five years or 150K miles, making coolant changes less frequent, but still necessary. OAT corrosion inhibitors provide excellent long term protection for aluminum or cast iron but may not be the best choice for older cooling systems that have copper/brass radiators or heater cores. There have been many problems documented with this type of coolant. Other manufacturers that currently use OAT type coolant as factory fill include 1996 and up Audi, Jauguar, Porche, Volkswagen and Land Rover, 2001 and newer Saab, 1996 and newer Toyota, Nissan, Honda and Mazda. Many GM vehicles that this coolant was spec'd for developed problems with engine cooling passage gaskets deteriorating to the point of failure, leading to expensive engine repairs. More importantly OAT type coolants have been found to form sludge deposits in engines that have open air, non-pressurized coolant overflow bottles as found in all Jeep WJ Grand Cherokees! It has been shown that Dex-Cool and its clones form heavy sludge deposits in the open to the atmosphere coolant recovery bottles of many vehicles, these sludge deposits are then sucked into the radiator and engine as normal coolant heating and cooling cycles occur. Once this has happened, it may be impossible to fully remove these deposits from your radiator or engine! Dex-Cool also contains a known plasticizer in it's corrosion inhibitor package. That means some cooling system components and seals may eventually fail after prolonged contact with Dex-Cool. The end tanks found in all WJ radiators are made of plastic and will weaken and eventually fail with prolonged contact to Dex-Cool and it's clones. Other cooling system components may or may not be compatible with OAT type Dex-Cool...... do you know how long they might last exposed to it?? Virtually all Prestone coolant products are OAT type coolants and should not be used in 2001 and newer Mopar vehicles. This includes Prestone Any/Make Model, it is a Dex-Cool clone, read the label! Don't use it! This doesn't make OAT type coolants necessarily bad, in a perfectly maintained cooling system, seviced every year or two not every five years (with a closed, pressurized coolant recovery bottle) they work just fine! These OAT type coolants are just a bad choice for our open air coolant recovery bottle WJ's, especially since there is a better alternative developed by Mercedes and adopted by Mopar in 2001.......... HOAT type coolant!! 3) HOAT Hybrid Organic Acid Technology coolant ~ this type coolant is usually dyed yellow, but may also be dyed orange, or red (Orange is the way Mopar dyes it!). HOAT type coolants are currently used as factory fill by Ford, Chrysler, Mercedes, BMW and Volvo. This coolant has been in use by Mercedes for almost 20 years with excellent results. It was first developed for long haul, over the road, truckers who wanted a coolant that could be used safely for hundreds of thousands of miles! The additive package in HOAT type coolants contains small amounts of silicates for added aluminum component corrosion protection. The small amount of silicate found in a HOAT type coolant is significantly less than found in traditional "green" IAT coolant, and not likely to fall out of solution forming the small green globs of snot we all remember when using traditional green Prestone! Most of the coolants in this catagory also meet European "GO5" specs for hybrid extended life coolant. Thats why sometimes HOAT type coolant is also called GO5. The service life for HOAT is also five years or 150K miles. This modern technology coolant is spec'd by Chrysler for every vehicle manufactured since 2001. It has all of the benefits of a modern technology long life coolant with non of the downside or problems associated with OAT or Dex-Cool type coolants. It is the best choice for coolant in every WJ. Period!! Case Closed!! Now on to "universal coolants" such as Prestone Any/Make Model and the rest that claim to be good for "everything" ~ Complete BS!! The problem with "universal coolants" is that a single formula cannot meet the conflicting OEM specs for IAT, OAT, and HOAT type coolants. If a universal coolant contains silicates, it does not meet the OEM OAT specification. If it contains no silicates, it can't meet the OEM HOAT specification. And if it contains phosphates or inorganic acid technology ingredients it cannot meet the OEM OAT or HOAT specs. Universal coolants are usually OAT or sometimes HOAT formulas and can be used to top off traditional IAT type coolants but then will not have the longer service life of a modern type coolant. If you do this the coolant should be changed annually. It is a very, very bad idea to mix OAT type (Dex-Cool or any Prestone "Universal" product) with HOAT type coolant. Sludge will form,and it will be near impossible to get it all out of your engine and radiator! |

Kan ik dan gewoon met de Coolant SP14 van Kroon Oil bijvullen bij de originele van Citroén ? |

Ja die kan er wel in, had ik ook met de riemwisseling gedaan met de pomp. Later die van mijn zoon ook mee gevuld. Ziet er geel uit maar ze noemen het groen, dan zeker heel licht groen. goed voor -40. http://www.kroon-oil.com/nl/producten/catalogus/seg_agri/krwf/329/landbouw/kroon-oil-winterfluids/coolant-sp-14/ |
