(I'm closing in on pulling the throttle body from my 1985) Two coolant questions: 1) I've been told that I'm going to have to drain at least some of the coolant from the radiator before I disconnect the coolant hoses from the throttle body. Should I drain it as if I were draining the entire radiator? How much should I drain? How much total coolant is in the radiator? 2) When I refill the radiator, what does the Guru suggest putting in it? I think I should be using distilled water for one portion - what kind of coolant should I be using for the other part? |

It's easy to use the petcock drain and dump it into a clean bucket. You don't have to drain a lot, a quart or more if it makes you feel better.
As far as coolant, I don't have a preference. Whatever green stuff is on sale. If the coolant is clean and has been changed recently, I just pour the same stuff back in (why I use a clean bucket). |

System is about 2 1/2 gallons total. Buy the premixed 50/50 green for the top off. You barely need to drain any as the TB hoses are near top of the system. BUT, how long since the coolant was flushed and changed?

I need to throw a monkey wrench into this...
I don't run 50/50... you see, water is the best coolant. It transfers heat better than any other liquid. Now, anti-freeze is just that, protects when it gets cold and keeps the various metals from eating each other to bits... however, depending on your climate, you can mix it down... I use 70/30 water to green. When I lived in DE, I ran a 60/40 in the winter, and then thinned it out to 70/30 in the summer... I run 70/30 year round here. just some food for thought. |

Yeah that TB coolant connection is a stupid thing.
The coolant in the TB is trapped above the thermostat which can be fairly water tight, but I guess it should drain back into the heater line for the most part. If you don't want any running down the front of the motor then have a shop vac nozzle right there as you loosen the hose. The 50/50 mix is a ripoff, costs almost the same as the 100% stuff! I've never found a car manufacturer to recommend distilled water, so if I forget to buy some, I just dillute with hose water. I always keep an extra coolant jug to mix it. If I was a yuppie with no garage space I guess I'd just get the 50/50. I also use the prestone yellow stuff so I can use it in any car. I've run it in a few dexcool cars as well, and over time there will be no red coolant left in them to worry about. Keeping different fluids for different cars is annoying. What Andy said about the water being the coolant is 100% true, I probably go more 60/40 ish. The chemicals in the coolant will make up for any shred of difference in distilled vs hose water. I bet the trace stuff left in the radiator is way more than whatever you gained by removing minerals from the water you're putting in. But go too little on coolant and you risk corrosion in your system, especially the heater core in long periods of non-use, and of course freezing. If someone is in a warm climate and wants some free coolant improvement, I recommend they run water wetter with 90% water. |

I recommended the premix to Jon just because it is so much easier. Not sure what the quality of the Philly city water is these days. The yellow antifreeze is the same as the green, just bittered so cats and other animals won't drink it. It was first implemented due to a California animal lovers suit, but now some stores out here are beginning to carry it as well.

After making the huge mistake of using 100% water, thinking it'd be very short term, I stay close to 50/50 (distilled is cheap) for anti-corrosion in these multi-alloy engines. BMW and Toyota sell $35/gal coolant which, as far as i can find out, is specially formulated to empty the customer's wallet; oops, I mean maximize corrosion protection in their engines.
My aluminum radiator had a generous coating of something, which I removed using a MB procedure of 10% acetic acid w/ water, running the engine to warmup, then flushing/refilling with coolant. |

That's why I always run 30% coolant.
If you are going to run pure water, get distilled. |

Racecars run it because it's against the rules to run antifreeze. Antifreeze on asphalt is slipperier than water on ice. |

Yes water boils at 200, but the coolant system is pressurized. The water will not be allowed to expand and therefore boil until much higher...240 - 260 maybe? System dependant.
I run water only in all the vettes with some pump lube and water wetter. Until winter, when I throw in coolant to keep the blocks from cracking overnight... i have no idea if the long term effects are good or bad, i seem to change radiators and rebuild blocks way too frequently to see them. |

I suspect the water wetter has some element of protection built in for metals and if you use good distilled water, I don't see much problem.

Yeah...but...
There is a lot of conflicting information I've read about WW over the years. They do claim that the product protects just like EG but I don't fully believe it. This feeling is not based on facts, but on the lack thereof. In other words, in my research, it's never been proven to protect against corrosion, but it has never been proven "not" to, either. I rarely take a manufacturer's claim as enough. Otherwise I'd take Zicam for this cold I have right now. |
