Q: Water and Sealant Mixture Found in Coolant Tank.

asked by on October 25, 2017

Hello. I just recently purchased the car from an individual through craigslist. Since the purchase I’ve had to replace the coil pack, engine mounts and battery. Today when we were waiting on the car to be inspected for registration, I noticed that in the coolant tank there was water and a sealant mixture mixed in with it. My concern is: is this safe to drive with just water? If so, how long? If not, and the coolant needs to be flushed but, a leak is then found...how much is that cost? If there’s other ideas you have in regards to mitigating this issue. Please, let me know. Thank you.
