Ek weet bittermin van kar engins. Gister het ek seker omtrent 250ml water in daai wit water tankie langs die radiator cap ingegooi. Op die swart cap staan "coolant". Nou is die persoon wie se kar dit is bekommerd dat ek water ingegooi het, want op die swart prop staan "coolant". Hy het nou vir agent gebel en dit so verduidelik. Die tegniese persoon wat daar werk het vir hom gesê dat dit okay is vir so 30 dae of wat, maar sal voorstel stelsel gedrain word en vervang word. Hulle vra R30 per liter. Volgens my was dit nog altyd dat jy 1 liter anti freeze of anti heat of wat in jou radiator gooi saam met jou water en nie net "coolant wat jy teen R30 per liter moet aankoop nie. 

Is ek agter op tegnologie dat net ou karre op water kan ry in radiator en nuwes net met spesiale coolant teen R30 / Liter?

Geert, ek is nie bewus daarvan dat slegs bymiddel gebruik word nie .Dit is altyd beter om die regte verhouding van bymiddel en water in te gooi.   Die bymiddel of "coolant" is in elkgeval ook maar 'n vooraf gemengde vloeistof wat water en chemikalië bevat so 'n bietjie meer water sal nie kritiek wees nie.  Gewoonlik is die verhouding water tot bymiddel in die ongewing van 2:1, maar die motor se handleiding sal die presiese verhouding aangee. As jou vriend se verkoelingmedium wel 'n water/bymiddel mengsel moet kry, sal die effense verdunnig wat jy bewerkstellig het deur net water by te voeg, nie skade doen nie.  Hy moet miskien maar die volgende keer net bymiddel ingooi as die vlak weer daal om die verhouding te herstel.  Daar is verskilende bymiddels beskikbaar.  Maak net seker julle kry en wat die regte bestandele bevat.  Dit sal ook in die handleiding aangegee word. Ek dink werklik nie dis nodig om die vloeistof te dreineer en met "coolant" te vervang as dit selfs 100% "coolant" moet wees nie want jou aksie het maar die verhouding baie effens verander.

Ek wonder net waarom daar 'n tekort aan verkoelingsvloeistof is.  As dit ook 'n lang tyd, sê 'n jaar of meer gebeur het, is dit nie 'n probleem nie. As die vlak egter oor 'n relatif kort periode gesak het, behoort hy die oorsaak te soek en te herstel.

Die coolant is 'n persentasie  Anti freeze en water.  Dit is baie min dat dit onder normale omstandighede so koud word hier in SA dat die water in die radiator vries.  Maar dis ook nie onmoontlik nie.  So my opinie is dat daai voertuig heel skaflik sal werk in die temperature van Nov Des Jan Feb tot Apr.

Toe ek my voertuie nog self gediens het het ek een bottel anti freeze saam met die water in my voertuig se radiator gegooi.  Nooit probleme gehad nie.

"Coolant" is a mixture of water and "Glycol"( is a water-miscible coolant that is frequently used in heat transfer and cooling applications. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics. Glycol comes in two varieties: ethylene glycol and propylene glycol.)

by adding 250ml of water to a complete cooling system of a vehicle is negligible. (it is like you add a glass of water to 5 l wiskey)

The dealer is out to make money

you must ensure that u use the correct specification for the coolant mixture as the chemical structure in the coolant can cause wear and tear of the materials used for the Water pump seals and type of alloy used in the engine.

Cast iron Block and Alu will use different formula for the "antifreeze"

hulle vervang dit in elk geval elke 150 000 km as ek reg onthou, dink daar is ook sekere aantal jare hang af wat kom eerste.

Greetings Geert,

250ml That is a cup of water, if that is all it needed I wouldn't have bothered.

Quite a few years back I owned a VW Combi on which the aluminum cylinders had corroded and started giving problems. The VW people said I would have to pay for new cylinders as I had filled up with plain water. After insisting that they go through all their records they agreed that it was they who as part of the service had refilled the system with their recommended coolant. There was no charge for replacing the cylinders.

It could be the switch to the use of aluminum which can not handle the chemicals that normally contaminate the water in an internal combustion engine.

Go in safety.

I have never seen anybody add water at the expansion tank.

If you have to check water level, you do it on the radiator cap, and normally when the system is cold.

The expansion tank is there for when the water gets hot and need some place to go. As your engine cools down again, the water is "pulled" back into the engine.

No, you are quite wrong Ed. You NEVER touch the radiator cap unless you have to work on the radiator. That is a sure  way to make the cap it leak in future.  Modern vehicles are much different from the pre- 1980 or so ones.   If the petrol attendant tries to open the radiator cap, you should clap him plenty around the ears but I am sure they would know not to do this as the expanding steam is sure to cause burns too.       If there is no leak in die radiator, it will always be full up to the top and you only need to top up the expansion tank.

Sadly you have ruined the motor which will soon stop running. Perhaps apologize now and maybe you two can share the costs of a new engine? Looking at about R65,000 but at least your "friend" now gets a new guarantee.

No more vroeteling !

You should add "grappie" in future Duncan!  Fanus Rautenbach used to do this when some listeners did not appreciate when he make subtle jokes on radio.

I agree Fred, never open the radiator cap to add water or coolant, whether the engine is hot or cold. Check the coolant level in the expansion tank.

I do sometimes check the level in the radiator as well, but only in the morning and with a cold engine. If your radiator cap is faulty the coolant may overspill to the expansion tank / reservoir when vehicle is working hard - as it is designed to do - but does not get sucked back into the radiator when cooling down. I don`t know it is possible, but i don`t see any harm and it gives me peace of mind.

As said before, I don`t think adding 250ml water to the system should not do any harm. Mixing different types / brands of coolant is a big no-no due to different chemical reactions  as explained by Swanie. A few years ago I had to replace a leaking radiator and water pump on a Toyota with about 150 000km on the clock. Toyota technician could only "guess" that it was due to incorrect concentrate or type of coolant, not knowing that i did top up the expansion tank with a no-name brand of a different colour a few months earlier. It is possible that I already had a leak somewhere in the system, but i more likely caused the damage by mixing different types of coolant.

Very expensive lesson learned!

Looks like I stand corrected.

Bottom line, if your system needs regular topping up, something is wrong.

Swanie daai verhouding van jou Whiskey/water-mengsel klink mos vir my na heeltemal voldoende coolant.

Is ek reg as ek sê n motor kan sonder enige probleme hardloop net op gewone water....sonder enige byvoegsels? Is byvoegsels nie maar net daar vir "extreme" gevalle nie.....soos ys weer waar radiator water kan vries nie?

Nee beslis nie!  Die byvoeging doen basies twee dinge: Dit keer dat die water vries as dit baie koud is en dit verhoed roes.  Eersgenoemde is miskien nie so 'n groot faktor in meeste dele van ons land nie, maar die anti-roes-deel is van die grootste belang. Roes kan jou masjien oor 'n relatief kort tyd so beskadig dat dit vervang moet word, veral met die baie aluminium wat in moderne masjiene gebruik word.  Dit laat ook die verkoeler aanpak sodat jou voertuig sal oorverhit.  Moet dit nie eers oorweeg om nie die regte hoeveelheid bymiddel te gebruik nie.  In 'n noodgeval kan jy net water gebruik, maar dreineer dit so spoedig moontlik en vervang met die regte mengsel.

Net so 'n stukkie raad: water bevat maar altyd opgeloste suurstof en ader gasse wat in die lug voorkom.  Dis waarom visse in water kan oorleef.  Jy wil so min as moontlik suurstof in jou voerkoelingsmedium hê.  Kook dus eers die water, as jy kan vir 'n paar minute.  Dit dryf die suurstof af, voor jy dit in die verkoeler gooi.  As jy eers water kook voor jy dit vries, kry jy ook mooi helder ys, sommer so terloops.

Antifreeze/coolant comes either as the concentrate (95%) or diluted to various concentrations for direct addition to the cooling system. The latter is "cheaper" to buy, but then so is water. Buy the concentrate and dilute to the specs given by the vehicle manufacturer. The mixture "ages" with use and has a tougher job when mixed with "aggressive water" that contains corrosive salts. It is generally suggested that you drain,  rinse and replace at about two year intervals. Leaks introduce air that promotes corrosion, so fix them as soon as possible, as the long-term consequences can be expensive. There is a dye marker that helps you see where the stuff is getting out.
