Heater didnt fit.
Although the heater core did not actually fit my vehicle due to the tanks being too big, an immediate refund was given and no hassle to return the unusable part. Maybe I can bless someone else with it one day. I did order the tubes (heater core) from 1A Auto about a week or two earlier and they were exact matches and fixed my problem. Will do business again! Thank you for your great service and hassle free understanding! Joel

Ask a question to 1A Auto customers who purchased the product
does the heater core come with the connectors?
Carlos S June 20, 2017
No, but you may transfer the OEM connectors onto this part.

Antoinette E July 2, 2017
Yes it does. But for my 2004 Nissan Frontier the tanks on the heater core were too big to squeeze into the heater core compartment.
