I'm finding out dragstrips don't allow traditional antifreeze so to be legal it has to be removed and replaced. Since there are water jackets all over the inside of the engine how does one get it all out? I know there are drain plugs in the block but does that allow all the coolant out? Thanks, -Steve-

I would suggest just flushing it out with copious amounts of water. In my case, I found that the drain plugs in the bottom of the block didn't actually go through into the water jacket, so removing them didn't achieve anything. You could knock a couple of core plugs out, but that is hard work if the engine is in the car. I use this stuff now: 
It's probably not available outside of Australia, but I'm sure you will be able to find something similar. ------------- I've finally given up drinking for good...........now I only drink for evil. |
10 Tenths Race Coolant Inhibitor Concentrate is a non glycol based coolant inhibitor concentrate that protects against corrosion, cavitation, scaling and oxidisation in vehicles that do not require an anti-freeze anti-boil coolant. It is an effective engine coolant that uses a hybrid organic acid technology (HOAT) inhibitor to provide maximum protection against corrosion whilst providing superior heat transfer to significantly reduce engine operating temperature.

There are some similar products here in the US. It's just a lot of grief for street car guys like me who don't race every weekend. If I was in a warm climate I wouldn't worry about running that kind of coolant but since I'm in the midwestern US (and it's been a brutal winter this year) I don't want a cracked block. -Steve- |

The two hex plugs, one on each side of the block DO enter the core. If you take them out and nothing drains, they are clogged with debris. Just put a screw driver in the hole and break out the debris.....I see it all the time when draining engines. ------------- Ross K.

It's the same way at circle tracks. Big fine if they see green fluid under the car after a overheat, or wreck. Even with the core plugs removed it usually takes more that one round of flushing to get all the color out. I've always used orange/amber colored antifreeze. If I don't get all the antifreeze out, they can't seem to tell the difference between rust colored coolant , or coolant with a tiny bit of amber or orange antifreeze still in it. ------------- 66 American SW, 66 American 2dr, 82 J10, 70 Hornet, Pound, Va. |

That rule only applies to race/modified cars. Cars registered with plates that only are run occasionally are usually exempt. Of course some tracks might put that rule in but it Isn't an NHRA rule.

Yes, some tracks like C.I.D. say so in their website "Track Rules" section. I've sent inquiries to other tracks asking them since it's not in their posted track rules. One track said if it's trailered in, no antifreeze. If it's driven to the track it's allowed but discouraged. -Steve- |

Good fun when your radiator hose blows off and all of that nice green coolant goes under the slicks at the back, change of underpants required thanks. ------------- I've finally given up drinking for good...........now I only drink for evil. |

Is it because it is slippery or for Environmental reasons? There is pet safe Propylene Glycol, (which by coincidence is an ingredient I saw today in the ingredients of the Coca Cola Freestyle dispenser drinks that people consume). ------------- 37 Ford Tudor 60 hp V8 flathead, all original, never restored 69BBB3904spAMX 70 Camaro 1st car 74 Hornet Hatch 6 cyl floor/auto 2007,2008,2009 PT Cruisers Aluminum Deck Car Trailer |

It is slippery and hard to clean up, almost like putting oil down. ------------- I've finally given up drinking for good...........now I only drink for evil. |

Much worse than oil. Oil they have the technology to clean. Having been loose in it at the 1200 foot mark I can verify it was a puckering experience. Did stay shiny side up. This was at an evening race, and a street car had puked the entire engine at the top end. They worked on it for an hour and I was one of the first reasonably quick slick cars. Extraordinarily disturbing when your engine suddenly revs out of control and hit the rev limiter when you are already doing 130. Shut it down for another hour to work on the track more. Anti freeze is bad stuff. Not practical to take it out of a street car though.

I have always used antifreeze in my race car. Luckily I never had a problem but I guess I need to change that. ------------- Best 1/4 mile 8.99, 1/8 mile 5.71, 60 foot 1.27, no power adders |

The rule at our local track is 13.99 and quicker water only....but since newer cars can run into the 11's not sure how that may apply now...I think I will leave antifreeze in the AMX this year...and only change out the Gremlin....I put coolant in it in the winter....do not like fixing freeze plugs.... ------------- Jim....AMCRC Treasure Valley AMC Club, Pres 69 AMX 401/727 74 GremlinX 401/727race only 73 Matador 2dr HT 360/727 |

At Mission Raceway in Vancouver BC they don't want the antifreeze, though I have not seen them enforce it stringently on street cars. They seem to not be excessively worried if there is a catch bottle. The permissable option seems to be "Water Wetter", which does give the boilover and corrosion protection, but does not help with freezing. Might be an option for garage kept cars and those in California. Chris

How do you flush out existing antifreeze? The block has drain plugs but that won't get it all out. Do you just refill with water, run it, drain it and repeat several times? -Steve-

I've been reading a bunch on what to use for coolant. Arguments about de-ionized water, distilled water, Water Wetter..... there are a ton of opinions. It's going to be a pain to swap coolant and antifreeze twice a year just to hit the track a few times. -Steve- |

It sounds as though not too long in the future you'll only be seeing EVs running at the track :) Definitely going to be a pain if you occasionally run a car at the track. Also, I recall when Englishtown was open, there was always a few of the imports that would blow something and they would dump synth oil on the track and it would quite a while to get that cleaned up over regular oil.

Spoke with my engine builder, he prefers distilled water, Red Line Water Wetter and a touch of Bar's stop leak. Walmart has distilled water for under a buck per gallon and Water Wetter is $10/bottle so it's the economical choice. Started draining the antifreeze from the AMX this eve, will flush system with the cheap distilled water. Once it's flushed out I'll refill with distilled water and add the Water Wetter. -Steve- |
