Rust in coolant
On a routine coolant change, I noticed that the radiator is spewing out
a lot of rust. I filled and drained the coolant a couple of times, but there still seems to be a lot of it. The rust wasn't there during the last coolant change. What could have caused it? Is it a bad sign? |
Re: Rust in coolant
did you use OEM coolant? Premix? or tap water?

Re: Rust in coolant
Very sharp, Earle :) But I was asking about a 94 Civic 1.5 liter. Curly, yes indeed, it was filled with cheap "Whiz" coolant (and distilled water). But I was nervous because I read a post that said that rust is a classic sign of past overheating. AFAIK this car has never overheated on me, the temp needle never event went up halfway. So it's definitely the Whiz, and not overheating? |

Re: Rust in coolant
I don't know where you read this, but there isn't that much iron in a Civic
engine, not where the coolant can get to it. Maybe the cylinder walls, but if they are rusted up you have serious problems. I would flush the system. Use the owner's manual instructions, if you still have it. Fill it with Honda Genuine Coolant. It only takes a gallon of pre-mix, and there are too many different types of coolant out there, to take chances.
