      Don't buy ebay junk

      I first bought this part from ebay and It failed after 3 months. It's worth paying extra for a quality product.

      Problem solved!

      Just like everyone before me who suffered the dreaded tstat housing leak (thank you Ford!), I was able to find a new one here at American Muscle. It blew competition out of the water regarding price, and it came with a bonus I was not expecting. A new 197°F thermostat was hiding in the housing saving me even more money! I wasn't sure about the durability as it seems to be polymer plastic, but since i have it installed the engine is noticeably quieter. Most importantly, no leak! If you need to replace your tstat housing just buy this one and "get er done"! You won't find a better price. The install took me longer than I wanted, but I've got 1 arm so you know it's not impossible. Just take your time and double check your connections. Get a new temp sensor and throttle body mounting gasket while you're at this. Good luck.

      Good investment.

      Was leaking through the whole reservoir within days, swapped out with this and problem solved. Just remember to get some gasket seal!

      No More Leaks

      I discovered coolant leaking from my car on a Sunday while doing an oil change. Didn't even know what this part was until then. Did my research and checked prices and I have to tell you no one beats this price. This part includes the thermostat as well. If you're gonna buy this part from anyone buy from American Muscle. I managed to replace this part within 30 minutes. Be sure to clean underneath the old thermostat housing!

      Thermostat housing

      I've installed one before. So it didn't take more than half an hour to put in. Just remember the steps you took to get to the housing and double check after you have installed the new one. Helpful tips are. Easiest way to get to is to remove the throttle body. The wiring clip locks my break but they'll still push on and hold. If removing the hose clamps any of the hoses rip or tear replace them. Mi'jos going to the heater actually melted to the nipple. So I scraped off the old hoes as much as I could. Went to O'Reilly's to get a replacement hose make sure you bring the old hoes the get the right inside diameter. The replacement hose in the computer is too big so have them find one with the same diameter on the inside and also bring the old thermostat housing to make sure the replacement hose fits snug on the nipple. When tightening back down remember it's plastic so just tighten enough to be snug. In one of the most important things is you don't have to drain your whole radiator out of coolant. What do get some 50-50 and a gallon of distilled water to replace. Read your owner's manual and it will tell you which 50/50 to get period it recommends organic gold Series.

      Better than expected.

      Better than the OEM part. What surprised me was that it came with a thermostat as well!! Other competitors wanted 60 for housing and 45 for thermostat. Glad I stuck with American Muscle!! You rock!!

      Easy fix

      Quick installation and great product. It took me just about 30 minutes to remove the old one and replace with the new one from American muscle.. I refilled it with new antifreeze and purged for a little and had the new thermostat housing working like a champ

      Temporary Fix

      The housing is build nice and looks just like the factory one but I only got 10,000 miles before it started leaking like the OEM housing. Spend a little more for the metal thermostat housing
