A-Premium Coolant Reservoir Tank
This A-Premium tank is made for the newer Sentra models from 2013 to 2019.
A nice bonus is that it comes with the cap and some tubing. You won’t need to hunt for extra pieces to finish the job. The quality looks and feels just like the original part.

SCITOO Aluminum Radiator
The SCITOO Aluminum Radiator is a full cooling system upgrade for 2007-2012 Sentras.
This all-aluminum core is strong and cools better than old, clogged radiators. It works with both the 2.0L and 2.5L engines from those years. The welds look clean and the fins are straight.
Installation is a bigger job than a simple tank swap. You’ll need to drain the coolant and remove a few hoses. But it’s still a job a determined DIYer can handle over a weekend.
Pros:
👍 Full aluminum construction
👍 Fits multiple engine sizes
👍 Better cooling performance
👍 Replaces many OEM part numbers
👍 Durable build for long life
Cons:
👎 More complex installation
👎 Heavier and bulkier to ship
👎 Higher price than a plastic tank
My Honest Opinion:
If your radiator is leaking or not cooling well, this SCITOO unit is a great fix. The aluminum build will outlast the original. It’s a solid investment for keeping your Sentra on the road for years to come.
A-Premium Cooling Fan Assembly
This cooling fan assembly keeps air moving across your radiator when you’re not moving.
It’s designed for Sentras from 2002 to 2006. The unit includes the motor, fan blades, and shroud all in one piece. This makes for a simple swap when your old fan dies.
The plug connections are correct and the mounting points line up. You’ll need to disconnect the battery for safety before you start. The job itself is not too hard with some basic tools.
Pros:
👍 Complete fan and shroud assembly
👍 Direct fit for 2002-2006 models
👍 Plug-and-play electrical connections
👍 Good airflow for cooling
👍 Affordable for a full assembly
Cons:
👎 Bulkier to ship than small parts

My Honest Opinion:
If your fan has stopped spinning, this A-Premium assembly will get you fixed up. Overheating in traffic is no fun. This part solves that problem for a fair price.
Coolant Reservoir Cap
This simple cap fits a huge range of Sentra models from 1990 all the way up to 2012.
A bad cap can cause coolant loss and overheating issues. This one has the right pressure rating for your cooling system. It seals tight and releases pressure when it needs to.
It’s the easiest and cheapest fix on this list. You just twist off the old one and put this new one on. It takes about ten seconds and could save you from a big repair bill.
Pros:
👍 Fits over 20 years of Sentras
👍 Correct pressure rating
👍 Very low cost
👍 Instant installation
👍 Prevents coolant loss
Cons:
👎 Only a small part, not a full fix
👎 Won’t help if the tank is cracked
👎 Easy to lose because it’s small
My Honest Opinion:
Always check your coolant cap first if you have cooling issues. This little part can cause big problems. For the price, it’s smart to keep a spare in your glove box.
A-Premium Fan Assembly (2000-2001)
This is the specific cooling fan assembly for the 2000 and 2001 Nissan Sentra models.
Older cars like these often need cooling parts as they age. This unit replaces the original factory part numbers directly. It comes with everything you see in the picture.
