Great price, fast delivery, easy installation

Arrived in 3 days, arrived in good condition and very well packaged. All screw holes were perfectly aligned, took about 30 minutes to install. Would buy this again.

Pros
  • Rugged construction - made from quality materials to withstand heat and vibration under the bonnet
Cons
  • Hard to say

Sensor in wrong position

2 stars overall as mine came with the sensor in the wrong position it cost me an extra $150 to have this checked engine light. Make sure the sensor connector is facing down. When it's pointing up, it's showing you the check engine light! Everything else is good so far!

Pros
  • Direct replacement - this engine coolant reservoir is the same fit and function as the original part
Cons
  • No

Mismatched Bolt Holes

10/22/20202 of 4 bolt holes misaligned. The sensor connector for the tank was deformed and the connector on the truck side did not fit. Freightliner's factory price was $363. It was half the money. I reused my sensor, grounded the top right and bottom left mounting holes and used it anyway. Let's see how long this lasts.

Pros
  • Ideal Solution - Designed for Seamless Installation
Cons
  • Contact Seller

Tried to save a few bucks and lost.

I installed this a few months ago and it seemed satisfactory although the bottom mounting hole didn't match up but since then I've had coolant leakage problems, as the sealing surface of the outlet cap is not smooth enough for the o-ring to seal on the cap. It's not very well formed. I would recommend buying the original tank.

Pros
  • Robust design backed by 100 years of automotive aftermarket experience
Cons
  • Not bad but...
