I changed my coolant the other day and used this brand called Mototech. I thought they were all the same, but now I read here that I should have used Honda coolant. The Mototech stuff has phosphates. Should I change it again or is it fine? It's a B16 CRX.

 

 

I would use Honda coolant. THat way you don't need to worry about a seal going out as much or water pump, radiator, etc. I think last time I bought it at dealer it was about 10 or 12 bucks.

 

i just use extended life prestone. its suppose to be silicate and phosphate free. saved 5 whole dollars by not going to the dealer.

 

yeah, just check the ingredient list on the back. I found cheese-ball Target brand "Car and Driver" coolant was phosphate free...

 

Coolant? I'm running straight water + waterwetter!

Works only in LA though, with a garaged car...

Prestone extended life 50/50 works pretty well for coolant. They're the new red stuff, not the old green stuff...

 

yikes!
i was under the impression that some of the ingredients from coolant were necessary. fill me in here.

i am well aware that water has better cooling abilities, as well as the purpose of the water wetter, but no coolant? fill me in.

 

coolant is usually called "anti-freeze" in other parts of the country besides LA. It lowers the freezing point of water when it's blended in. Coolant is also a corrosion inhibitor....makes it harder for rust to form in your radiator/engine cooling jacket passages.

 

Really you're going to want phosphate free coolant on anything that has an aluminum radiator.... I know Volkwagon and Mercedes are like this and they require you to use their coolant which is phosphate free because it won't clog the radiator.. For Honda I just use factory or Prestone...

I was thinking of the corrosion part of the equation too. But there isn't much if any corrodable stuff in the cooling system, that I can think of. Water jackets are aluminum; the iron sleeves don't touch water... the head & block is Al. Water pump should not rust. Cross pipes (back of the blocK) are also aluminum.

Long story short: I'm in LA, car parked in garage. It won't freeze!

 

Anyone know for sure if Prestone is phosphate and silicate free.

 

 

check the ingredients on the back. It would be reflected in the label.

 

Prestone is phosphate free. Well the green stuff is, I just checked.

 

did you guys know that only a couple drops of soap is the same as a Redline water wetter!!!

 

Doesn't it need to be silicate free too?
