Product Details

Replace the thermostat on your Discovery Series II, 1999 - 2004 vehicle with this top quality replacement (Part # PEM100990) from Atlantic British!

The thermostat regulates your Discovery's operating temperate by restricting the flow of coolant from the engine back to the radiator, making it a critical part for your vehicle. If you notice an issue with you Rover overheating, it may be time to replace your thermostat. It's important to switch out a bad thermostat at the first sign of failure, or risk suffering further, costly damage to other engine components.

Atlantic British carries Land Rover thermostats in stock and can have them delivered to your home or shop immediately!

As you repair your Discovery Series II, think about replacing all the hoses to save time and money. We've assembled all of the hoses (and thermostat) you need for your Disco 2 so you can have them all installed at once, rather than risk another trip to your garage when the second one breaks!

An exact replica of the original equipment part. Easy to install. Hopefully it lasts 200,000 miles like the original.

This was the right product for the right money. I chose the less expensive thermostat over the Land Rover thermostat. Fit well and appears to be working well.

The thermostat was easy to install, even with the aftermarket upper hoses. My 2001 Disco is no longer suffering from over heating thanks to this cheap(not referring to quality, but price) part.

The temperature in my Land Rover now runs about 10dgrees cooler. No more leaks, and has a year warranty. Just make sure when you install the thermostat that the slanted tube goes to engine side and the straight tube direct to radiator hose otherwise engine will overheat under load.

Fast, accurate shipping of my order. Better prices than I found elsewhere in the U.S. In some cases, China and Europe were cheaper, but shipping would have taken a lot longer.
