Customer Reviews
Helped eliminate my Dmax overheat issue :)
Great products that not only fit my vehicle they also worked correctly.
These thermostats were a little tough to get to for a novice mechanic like me, but I got to know the van a little better, and I won't think twice about doing front engine work again if needed. The quality and source of the thermostats was the most important, and these were the ones most highly recommended. Shipping and delivery were timely, and I appreciated the "might need" notes when shopping. I ordered both of the O-rings recommended. The van warms up twice as fast now, and the optimum run temperature is where it is supposed to be. Only 235,354 miles, should last a couple more years.
Truck warms up to operating temp now, heater works again and improved mpg.
Works great
