The LSHDLAM Coolant Reservoir for Ford Super Duty F250 & F350 is worth buying just to replace a perfectly fine but dirty existing tank! The quality of this reservoir is better than the original from Ford. This is so easy to install as it fits perfectly, just make sure you either save your existing hose clamp or buy a new one if you need it since this doesn't come with one. This coolant reservoir is a perfect match for my 2006 F350 SD Dually and I'm glad I found it. I just wish I found it sooner and replaced the cap... could have saved a lot of problems (if you know, you know)! ... show more

I installed this engine coolant reservoir tank on my car, and it fit perfectly. The quality feels solid and durable, just like the original part. Installation was easy and straightforward. It connected to the radiator and hoses without any issues. Since installing it, my engine has been running smoothly with no leaks or overheating problems. It does exactly what it’s supposed to do. Overall, this is a reliable replacement part. It’s durable, fits well, and keeps the cooling system working properly. ... show more
