NEED HELP FINDING A COOLANT LEAK

Postby Blanco_SB » Tue Aug 30, 2022 7:13 am

I’ve been having over heating problems after trying to bleed the system from installing a mishimoto fan shroud and nismo thermostat, I also put a z1 high pressure rad cap on the stock radiator to see if that would help. I live in Southern California so temps are over 100 every day right now. I drove for a while and temps were low but they suddenly rose so I pulled over and turned off the car and heard drops so I checked and saw a decent pool of antifreeze which stopped after a couple seconds, I let it cool down and topped off then went home. I go through about a gallon a week of antifreeze. Front driver side right by the wheel, I tried searching for any info but no luck. If anybody has any idea what this could be, it would be greatly appreciated.

Chasing a coolant leak is purely guessing without testing it in-place. Go get (or rent) a pressure test kit (not expensive). It's a special cap that you attach in place of your regular cap and a pump is attached. Manually pump up the pressure to 15 psi, and start tracing leaks.

If you want to get really fancy, add luminous dye and get a cheap blacklight. I keep both on hand for tracing leaks.

Thanks for the response, will try that tomorrow and see how it turns out. As for bleeding the air I see many different methods that I have tried but to no success, can you suggest any way to doing it?

Don't go too crazy. Make sure the overflow container is full, get it to operating temp, let it cool, add fluid as necessary. BTW, distilled water + WaterWetter is what you want. Leave the "coolant" on the shelf.
