Ah. Nice to see you step out of the motorad thread. For a moment, I thought you only post in there and don't know about the rest of the oddyclub.RinconVTR said:I've been using Prestone Extended life as long as I can remeber.
I have no idea why you would say such a thing. LOL!dvpatel said:Ah. Nice to see you step out of the motorad thread. For a moment, I thought you only post in there and don't know about the rest of the oddyclub.![]()

Ditto on the Prestone. These guys have been producing glycols since forever. IMHO, I think their use of buffering solutions (weak organic acids) to give wonderfully long coolant life is as good as anybody else's. It's what's in my ancient Accord right now. Prestone for my car, and a bottle of Geritol for 0dyfamily.RinconVTR said:I've been using Prestone Extended life as long as I can remember...
So based on the above data, the Honda Type 2 has the potassium that neither Prestone nor Zerex has.Search the MSDS sheets to see the contents of the coolant.
Honda Type 2:
1) Ethylene Glycol 47-53%
2) Diethylene Glycol <3%
3) Potassium Hydroxide <3%
4) Hydrated inorganic acid, organic acid salts <5%
5) Bittering agent >30mg/kg (Added so you don't eat it)
Prestone 50/50 prediluted engine coolant
1) Ethlene Glycol 45-55%
2) Diethylene Glycol 0-5%
3) 2-Ethylhexanoic Acid, Sodium Salt 0-5%
Zerex Asian Vehicle Coolant 675130
1) Ethlene Glycol 40-50%
2) Diethylene Glycol 1.5-5%
3) Organic Salt 1.5-5%
Do you have to "burp" the engine block upon refill and start up, or are you just emptying the radiator? (and leaving the remaining coolant in the engine block).It's just so easy to do with that little drain plug that can be opened and closed by hand at the bottom of the radiator.

What color is the cap? Black?I've been using Prestone Extended life as long as I can remember.
Edit: At some point in my life, I hope to be able to spell and proof read.
