This winter my radiator broke because I forgot to put antifreeze in it and the ice blew it up. It`s been sitting in my driveway since late december and today (may 4) I replaced the radiator. I found out I had to replace the battery as well. I drove it a couple times (just a quarter of a mile and back) and it was great. Tried to go somewhere later and it had no power and was smoking from the engine bay and from underneath the car. I filled it up with premium gas, put lucas fuel injector cleaner in, and water remover. when I drove it back home, the exhaust pipe near the catalytic converter was red hot! and it seemed like it was on fire around that area (more and more smoke even when the car was off). What`s going on????

Re: Sudden major loss of power!!
If the smoke was white it means your engine is leaking antifreezeinto the cylinders and burning it in the combustion chamber. the engine block may be cracked because the block probably froze during the winter as far as the catalytic converter it is probably clogged because the antifreeze is coating the inside of the converter

If you are sure that it is antifreeze and reservoir is full, start up your car and put it on car ramps or a rack and find the location of the leak. You can run the car until temp gauge registers mid-temp especially in cold weather. A fan blowing on the motor will help cool engine. Good luck finding the leak.
Drain out all the water in the pipes for hot and cold then put in Potable antifreeze.. Not the kind for your radiator. Leave all water faucets open so any water left behind won't build up pressure and crack a pipe. Make sure the coolant in the radiator tests good for the temperature you expect to see. Adjust radiator antifreeze as necessary.
Any antifreeze that has ethelene glycol in will do . For freezing conditions a mix of 55-60% anti freeze will be required . Castrol concentrate is a good one and mix it before pouring in the radiator. So for a 10 litre system mix 6 parts of antifreeze to 4 parts of water. Work out your requirements like that.
If you started the car and checked the hose more then likely it's comeing from the radiator nipple where the hose connects and is running down the hose. I feel you need to have it pressure tested,
Most shop will not charge for this. They put on a presure pump on your radiator cap go's and pump it up to find the leak exact location. Good luck to you,
A water pump would not likely cause loss of water,mainly overheating problems.First fill the radiator full and the overflow full,you can use water to do this,it is not necessary to waste antifreeze.You do not need a 100% mix of antifreeze.During winter where it gets below freezing,you really only need about 70% antifreeze to prevent freeze.Maybe a little more if you are 1 or 2 states from Canada.If you open the hood and let the car run,watch the tubes and the radiator and the hoses,follow anything hooked up to the radiator.If you end up getting a big leak or puddle,dilute it down with tons of water.Birds for some reason like the taste of antifreeze however it kills them.Good luck!

let it thaw out ,then see if you have popped a core plug ,if no leaks then put in 3 litres of pure antifreeze and then try starting .petrol or diesel because if its diesel then the fuel could be frozen as well
Well one you cant "patch" a radiator hose, especially one under high pressure with quite a few bends on the V8 Q's. (I assume you are referring to the upper hose). First replace the hose, which will be more expensive than a Granada's :). Then I, Not saying you should do this, but again I would experiment with water instead of expensive antifreeze, at least checking for leaks. You probably don't want to bring it to 100% operating temp however as water has a lower boiling point than antifreeze. Ok let me just ******* and move on. YOU fill with at least 50% antifreeze when car is cold (more if the outside ambient temperature says you should). Start your Audi with the fresh fluid. Let her run for a while why you watch the temp. gauge on the left. Should stay right below 100 (center marker), possibly a tad over. Do not let it overheat. (this is assuming your gauge is working, and your temp sending units (3) and auxiliary fan are functioning. Look for leaks. Step behind the car and get your nose close to the exhaust. Does it smell like sweet antifreeze? Do you see white smoke? If neither head gasket is probably good although leak could be finding another outlet. Usually not with the v8Q's. Is your thermostat opening? Check and see if you have heat? if no heat then your coolant isn't circulating properly = bad thermostat, filthy radiator and coolant system needs major flushing or possibly worse your heater core is gone, which would indicate constant fogging on the inside of windshield noticeable when the defrost is put on and smell of antifreeze in the cabin. This would also explain a not so obvious loss of antifreeze. If indeed your heater core...sorry ...not fun on this car. Not fun at all. Good luck.
