Great price and no difficulties paying. I also love getting coupons emailed to me!! Thank you!

hopefully its in stock

Great store

good

so far all good.

The estimated shipping charge to 84087 was 12.00 but at checkout it was raised 7.00 to 19.00 Checked the heater control valve, Motorcraft YG133 before installation and found that the valve does not close all the way off. This will allow hot water to circulate through the heater core and cause hot air to be blown into the passenger compartment all the time. The valve is defective or poorly manufactured. Tried to save a little money but item does not work and has cost me a weeks down time already.

Great Prices and Very Fast Shipping. Will order again in the future. Customer Service was great when I called about a question with my order.
