No permanent solution. OEM better

Works but after a month you will see that the plastic cover is cheap! That means you know it's likely to break within a short period of time.

Pros
  • Best in niche
Cons
  • No performance

but it fits the 1998 Honda Civic perfectly

Seems cheap but fits the 1998 Honda Civic perfectly. Not sure if it seals well as I was still having trouble with the coolant not returning to the radiator. But there could be something else in the cooling system.

Pros
  • Very good value for money
Cons
  • Run Speed

Correct reservoir: Coolant Recovery Kits

I bought my 1997 Honda Civic which had some modifications done to the car and for some reason after the modifications the water reservoir wasn't installed properly so the tank fell in the headers and melted. I ordered this tank and it fits perfectly in my mount. Very happy

Pros
  • Lots of positive vibes
Cons
  • Not happy with everything

Getting Done Now

Looks solid from the start, comes with clear hose for in-tank use only. It doesn't fit exactly like the OEM for my 1997 Civic I had, but I've managed to fit it for now. The cap on the tank is slightly thinner than the OEM.

Pros
  • Rugged construction - made from quality materials to withstand heat and vibration under the hood
Cons
  • Vulgarity

Correct tank in coolant conversion kits

because the water tank was not installed correctly. After the mods, the tank fell into the sewers and melted. I ordered this tank and it fits perfectly in my mount. Very happy

Pros
  • Robust design based on 100 years of aftermarket experience
Cons
  • Upgradable
