My car was overheating like crazy, but this new radiator fixed it right up. Haven't had any temp issues since installing it, huge relief.
FAQS
Stop the installation and contact Philtop customer support. Please provide your vehicle information, order number and photos of the original and received parts so we can help review the fitment.
Some radiators include transmission-cooler connections. Check the specifications and compare the fittings with the original radiator.
A flush may help remove old coolant and debris when contamination is present. Follow the vehicle manufacturer’s service procedure.
