Radiator Fluid Low.

So i was driving and i saw a light steam coming out the front when i stoped at a light, Then i pulled over and opened hood and there was radiator fluid along the top of the radiator and the level was very low in the resovior. The fluid was the steam and I wanted to know what to do from here?

Take it to mechanic? How much does it usually run? Could it be a small or big problem?

Car is a 97 prelude. Thanks.

Re: Radiator Fluid Low.

i had it leaking from the bottom due to a bad hose, your upper hose could have gone out,

Re: Radiator Fluid Low.

From what you said, it's your radiator. Here's what probably happened.

Your stock radiator is an aluminum core and fins, but the endtanks (the top and bottom) are plastic. The process they use to bond it is just to heat and melt up and mold it together. This process leaves a very blaringly large problem and that is that it plastic and aluminum don't bond. They just seal for the time being.

So somewhere on the top of your radiator, that bond is slowly coming apart and it's leaking the super-heated radiator fluid out in the form of steam, but I bet when you stop your car and it cools down, you can see some fluid coming out. But if it's low, you'll not see it leaking out of the top.

Take some brake cleaner, spray it all over, let it dry. This'll make a sterile environment around the edge of your radiator. Next, fill up the radiator to the neck and watch where moisture begins to form, that's your leak.

There's no other choice but to get a new radiator. I'd suggest getting an all-aluminum one so if another leak develops (which I highly doubt would ever happen) you can at least get it welded back together.

If you do it by yourself, you'll find the task to be easy but time consuming. Good luck!

Re: Radiator Fluid Low.

I just had to replace my radiator in my 97 prelude sh. It had a pin hole leak at the top and I had the same symptoms that you described. I bought a new radiator from autozone and it was 107.00 with a lifetime warranty. Good luck, it is fairly easy to replace, just take your time if you decide to do it yourself.
