Review on 🔧 Enhanced Sinister Diesel 6.0L Oil Filter & Coolant Filtration System for FORD POWERSTROKE 2003-2007 - Effortless Installation, No Drilling or Part Removal Needed - Complete with All Hardware by Matthew Bell

Driven a thousand miles to change the coolant filter [first time] and both check valve handles are missing. It appears that both screws, one on each check valve, came loose and the screws and handles just fell off and are now missing. RATS! I've checked the system several times but never checked the bolts (to make sure they're fully tightened) - I've opened and closed the valves several times and haven't found any problems. Errr! I will still give the system 5 stars because the system works very well. Maybe I'm just unlucky and Sinister Diesel sent me spare parts (and another sticker!) :-) UPDATE: I called Sinister Diesel support about the problem and I'm not lying. .Within 30 minutes I received an email with tracking information for replacement parts. They were very nice, helpful and solved the problem quickly. I love this band! I will 100% buy from them again!
