Worse company ever! I ordered a defective water pump. The hole is too small for the thermostat. I tried to start a return online. Even though the part is defective, because it s the part I that fits my truck they won t let me return it. I will be filing a complaint with the Better Business Bureau and the attorney general. This is wrong and I m disable so I hope you guys are happy with yourselves.
