REVIEWS & TESTIMONIALS
I just wanted to tell you how much your product has helped me save money. I bought a van last year from a man who bought it for his business but he said on the way to get gas it started smoking real bad and then it died so he put it in the paper for sale lost big on it. I bought it for $500.00 thinking I’d have to replace the motor started messing with it a little found it needed a starter that’s why it won’t start so replaced it and it started but smoked bad white smoke I checked on a few products seen Blue devil for block seal followed the instructions 50 minutes later it stopped smoking and have been driving it ever since. Just wanted to tell you all that it works great.
Thank you, Charles

Reattach the hose, tighten the clamp and continue with the rest of the directions.

These are tell-tale signs of a radiator that is in need of service. When fluids are not changed often enough under severe operating conditions or in areas with hard water, scale deposits may form in the passages. Sometimes old fluids will jell or crystallize and can be seen in the system. To remove these deposits flush cooling system using a flushing agent and/or a flushing machine.
