The coolant capacity of the 2004 TOYOTA COROLLA 1.8L 4-cyl Engine Code [R] 1ZZ-FE is 6.9 quarts. To accurately ensure you have a 50/50 mix in your system after a flush (assuming you actually flush it until you have clear liquid draining out), is to add 1/2 of the coolant as straight coolant (not 50/50 mix), then fill the rest as distilled water. For ...

You can use a coolant mixture tester to test the coolant to water ratio. Any auto parts store should carry them.

Yes what you presume is correct. Depending on total volume of coolant (different for each vehicle) how much pure AF I put in, anywhere from 1/2 to 1 gallon, then top off with 50/50 mix. It is better to be over the 50% mix than under, you can go as high as 70%, so don't worry about putting a little too much pure AF after flushing the cooling system with ...

So you've replace a bunch of coolant related components and you want to know if anything leaks? You can borrow a coolant pressure tester from you local autoparts store in many locations (leave a deposit). You will place the tester on the fill cap (no matter where it is), pump up the pressure and then note the pressure on the gauge. Give it a few hours, ...

Nope that sounds about perfect. Remember there is a spring on the radiator cap that keeps the engine coolant pressure to around 13 PSI for most manufacturers. Water doesn't boil until around 242°F (117° C) at that pressure. The manufacturers want the water to stay as a liquid because that helps the radiator work better. (Liquid to vapor transfers heat ...

I have had the same problem for years on my 2001 Grand Am. We have replaced fuel pump, water pump, thermostat, head gasket (since it redlined after thermostat change) and nothing worked. Same thing, I was fine as long as I wasn't idling places. But, I live in Wisconsin and really all fall and winter it is fine, but once it gets above 80, I have to watch it. ...

You need to get this car to a Mechanic ASAP. Even though you keep an eye on the gauge. By the time the gauge is in the danger zone the damage has already been done. Spent the bucks now to fix it and save a bundle on the chance that thing Blows a gasket..........

Its not good to run with low coolant, even worse to run with no coolant. Actually it can be quite disastrous (possibilities include blown head gaskets, seized pistons and a number of expensive repairs), but many times this is a result of a leaky radiator cap which is easy (and cheap) to replace. Someone already mentioned the dyes for detecting leaks, but ...

If you can't see any obvious signs of leaks, or steam coming from anywhere if you run the engine, a likely cause is a cracked cylinder head gasket, which is letting the coolant into the cylinders and out of the tail pipe as steam. That could soon cause a lot more damage than the hassle carrying a water container in the car to top up the radiator. Personal ...

"Is it safe to continue driving with low coolant as long as I continue to watch the temperature gauge? " No, the temp sensor reads coolant temperature, if the coolant gets low enough to be below the temp sensor, now the sensor is reading metal temperature of the area it is screwed into (usually cylinder head), by the time it reads too hot on the gauge the ...

If you do not have any leaks, then your coolant is most likely getting burned and/or going into your oil. My guess is going to be a problem with your head gasket or some crack or warping in the head. I believe coolant in oil used to turn oil more brown and make it more foamy or milky. These days, the detergents and dispersants in modern oil can reduce ...

First, you do need to find out where the coolant is going. There is UV dye that can help with this, and if your car is smoking, that could be a sign that the coolant is leaking into the engine rather than on the ground. For the main question, "Is it safe", as long as you keep an eye on the temperature and it's not getting too high, you should be OK in the ...

Clear water is not a sign of requiring a flush. It might be a sign that you need some anti-freeze... Brownish water or any other color that is not the normal color of your coolant could potentially benefit from a flush. Plain water in our engine could potentially cause problems: Water will boil over and not cool the engine sufficiently. Danger of rust if ...
