Product Q&A

Hello, Will this item fit a 93 Ford E150 econoline van?Nikole L.Jan 26, 2023

Best Answer:Hi Nikole, I'm glad to assist you. No, it won't. Unfortunately, we don't carry direct-fit coolant reservoirs for the 1993 E-150. We suggest checking the local part stores around your area on what they have available to offer you. I hope this helps, and we thank you for inquiring.

Will this part fit a Toyota Sienna 2004?Jeanne F.Feb 28, 2022

Best Answer:Hi Jeanne, I'm glad to assist you. This would not be compatible since the original bracket (on the engine where it is mounted) would not match the mounting slot or bracket of this universal type of coolant reservoir. But, you can make it fit with fabrication and modification of the bracket to mount this in place. Grab our sale price offer and click the link below to order today. I hope this helps. Happy shopping. <a href="https://www.carparts.com/coolant-reservoir/dorman/rb603001?can=CPJE1043_20220228" target="_blank">https://www.carparts.com/coolant-reservoir/dorman/rb603001?can=CPJE1043_20220228</a>
