Took off the drain bolt on the block today...coolant flowed like wine, however....when i stuck my finger in the hole, it was like slimey. Why is it slimey, and how do I get rid of it? If I leave the bolt off...and put a hose to my radiator till the drain hole drains out..will that do?

I'll get pics

 

Here is looking down into the cylinder



and here it is ooozing out


EDIT: its only around this hole I think...maybe just at the bottom of the cylinder, but good coolant always comes out first

Does not look good

 

Its just in the area around the hole (NO thats not a euphanism for anything). I think flushing it out will get rid of it...

any opinions?

 

definatly flush it out... and keep an eye on it and on you engine temp... if it was that think it may have caused some clogging with could lead to over heating which as we all know is death to your engine...

 

flush yuor radiator and get some purified water i have seen thios on old radiators because of high mineral cvontent in the water from the water hose. or some one put stop leak????

 

Looks like some sort of stop leak. I think a good flush should get rid of it. And when you refill it do not use tap water when mixing the coolant.

 

I believe that is the silicate starting to drop out of the coolant. I bet it was not spec Honda coolant, or a low silicate, no phosphate formula, like FleetCharge.

Was it per chance Prestone green/yellow, installed with tap water?

You guys need to use distilled water too! (Just some advice for all.)

I've been thru this before (major problems with my detroit iron) and posted a bit on it, the search might find it.

Thank you. It was indeed prestone green, but I did not dilute the mixture. Hehe I could take a little sample and send it to you if you wanted!

Ima put everything together, and flush it out. Then dilute the prestone green with distilled water and put everything back in.

thanks

Sabastian,

If you used the prestone 100% as it came in the gallon jug, it is indeed silicate drop out. The solution was supersaturated under some conditions. High silicate content antifreeze can cause premature wear of the water pump.

I "believe" Honda recommends a low or no silicate formula. There are some "more" advanced formulations that protect better, and do not wear rotating components in the coolant stream like a high silicate content anti-freeze.

Thanks for the reply. Good luck!

what about that orange stuff..?

 

If you are talking about the supposed 5 year, organic acid based GM/Texaco/Caterpillar DexCool, I wouldn't drown my worst enemy in it.

Thats the stuff the started to dissolve the silicon elastomers in my intake manifold gaskets and started to delaminate my head gaskets in my GM cast iron. I had to break two of my Vortec V-8s down to the block with only 40K miles on them for leaks last year to replace the head gaskets and intake manifold gaskets for leaks.

It has other problems with turning into a brown goo when exposed to air (personally seen in my friends GM Car), and crystalizing. I think it was TEKEN I alerted to the crystals, and I think he found them under his radiator cap on his Honda with DexCool.

In fairness, the metal (both cast iron and aluminum) in my GM V-8s were the prettiest that I have seen. But the darn silicon elastomers were toast in both engines, exactly the same way. I do my own engines, so I have the old gaskets and the coolant. I am currently part of a class action suit against GM.

See this post:

I substantiated the problems with dexcool there and gave my recomendation for a low silicate, no phosphate formulation called Fleetcharge which I have switched to in my diesel equipment, tractors, cars and trucks. Its RED. I like it. A lot.

I would recommend nothing other the Honda Geniune Type 1 Antifreeze. Distilled water is a MUST. -HIT

In absence of distilled water, would water run through a water purifier, like a britta or pur, be as good?

 

Distiled water dosent contain solids or minerials and costs like a dollar a gallon at the grocery store. Your better off trying to use rain water instead of filtered water. Better than tap but still not what you need.
