Just the mere utterance of the word "Toyota" drums up thoughts and first-hand anecdotes related to the brand's reliability. Everyone knows someone who's owned a Camry or Corolla with enough miles to circumvent the earth a few times and still won't quit. Of course, this rugged dependability is something that we'd expect to find in Toyota's line of trucks and SUVs, and while it's mostly there, we found in our *last post* that the Tundra's cooling system pokes some holes in these stories, along with the radiator itself.

The cooling system is vital to the operation of any vehicle, but especially to the full-sized trucks that are hauling heavy loads. Unfortunately, cracked and crumbling inlet pipes is less than ideal for daily commuting, let alone when the need arises for hauling or towing. Luckily, we have the fix.

Plastic seemed to be the root cause for most of the stock design's issues, so we ditched just about every bit of plastic for our final design, especially when it comes to our end

No matter what brand is plastered across the front of your truck, the key proponent for purchasing it was rugged dependability. Toyota has long bolstered its name as one of the most unstoppable truck manufacturers out there. Toyotas are the preferred machine for traversing these environments from desolate deserts, swampy jungles, or just across the construction site. Toyota's quest for tough trucks didn't' stop with their full-sized Tundra, but as the miles rack up, there are some chinks appearing in this truck's armor, precisely when it comes to the cooling system.

A dependable cooling system is vital for the Tundra's workhorse status, which might hold up for most drivers. However, the harder these trucks work, the more stress is added to the factory radiator. Over time, the constant heat cycles of hot coolant degrade the plastic end tanks, which we saw firsthand on our donor truck.
