The radiator on my Peugeot 106 has started leaking very badly and needs replacing. I don't have time to fix it at the moment, so I'm taking it to a garage. How far can I drive it without damaging the rest of the car? Or do I need to get it towed?
In the case where you run it too hot, you could start messing up your head gasket or warping the head itself. If you have to, in a warm climate, use distilled water or just keep replacing the antifreeze until you can get it somewhere, after which you'll have to have the whole system flushed.
If you live in a cold climate your engine block could freeze and crack. Definitely do not use water in this case.
Are you just leaking from a hose or the radiator somewhere? You might already have a blown head gasket and you could be burning off the antifreeze in the engine. Is there any film or other liquid in your oil?
I would tow it if it's as bad as you say; head gasket repair can run $600 - $1,000 or more. A few bottles of antifreeze to get you there is obviously a considerably smaller investment (though I'm not sure how much your city will like you leaking antifreeze all over).
It depends on how much you are leaking. I've had a leak in a radiator and had to take it somewhere a few times, here's what I usually do.
- Fill the radiator completely full of water. If you can get it loaded, and it takes more than a few minutes to drain, you can proceed to step two.
- Drive slower than normal to your destination. Keep a spare gallon of water in your vehicle. Keep glancing at the temperature gauge. If you see it go above the mid line, then pull over immediately. Wait for the vehicle to cool down, and replace the antifreeze. Or else just call a tow company.
You should be able to take a vehicle at least 5, maybe 10, miles by following this advice. I should say that I live in an area that never freezes, so...
As with many things, it depends. I was once in the car when my dad drove about 15km at highway speed, not taking any special care, before remembering that he’d drained the coolant system of his Saab 900 and forgotten to re-fill it. The engine was up to temperature by that point, but we stopped straight away, found some water, and filled it up, and no obvious damage occurred — the car still runs fine years later.
On the other hand, you could drive a few hundred metres and blow your head gasket. In your situation, I would get a friend to tow the car to a garage, or maybe ask the garage if they can tow you — maybe New Zealand garages are just friendly but a lot of them are happy to!
If towing is not an option for some reason, and it’s not leaking too quickly, I’d just pull over regularly to top the radiator up.
How much you are safe to drive?
You are alright to drive till the thermostate opens the valve to the radiator and the leak starts to drain the coolant liquid, I can not say an exact time, cause it depends on the outside temprature, but if outside temp is 10 degree of celcius(43f) you may have about 10 minute, you are safe to go till the coolant temp gets to 70 degree of celcius (about 110f) afterward you do not have a lot of time, depend to size of the leak and the capacity of coolant liquid in your car
How can you temporary fix the issue to get to a mechanic?
Chew a gum and stick it to where you see the leak, move the car and check the drive path carefully for a new leak
If you have refilled your water reservoir then you need to bleed coolant system, some cars allow it to be done without starting the car(BMW) check your repair manual.
