Great condition
July 7, 2017
so far so good car is working! Will order more supplies from this website!
August 11, 2017
Already mechanically inclined but watched the A1 Youtube video anyway. It was spot on down to the pliers you would need to get the clamps off the transmission hoses. I took my time and it was about an hour and a half from start to finish. The part they sent me was an exact match for the car.
August 15, 2017
Ordered 02 Honda Civic radiator and it arrived 4 days later along with a couple extra parts. It was a perfect match. Easy install. Price was great and the rep. I spoke with was very knowlegable. Have since bought a couple more items and again remarkable service.
September 4, 2017
Good and helpful video I did follow the instruction very easy thanks now is working good my car.
1A Auto... great. UPS, not so much
September 18, 2017
1A Auto help and service was exemplary. The only problem I had was UPS beat up the part in transit. Nonetheless 1A Auto shipped a new part (radiator) promptly and it is working well.
Fit great
October 21, 2017
Took about 3 hours, but the radiator fit just like the one it took out.
Bad aluminum Trans fluid fittings
November 4, 2017
On the radiator that I received, the aluminum fittings for the transmission fluid hoses (at bottom of the radiator) were made of very thin material. After install and test drive, trans fluid was leaking badly from the fittings. I tightened the nut slightly on one side and the fitting failed completely. The flared material inside the nut was not substantial.
November 13, 2017
Very good price, very good parts and very good service. We are so happy. We will come back.

Civic Radiator arrived damaged
June 27, 2018
My radiator arrived with the box opened on one end, sealed with tape instead of the metal staples. I removed it from the box, one of the ATF connection tubes on the radiator was bent so bad it was kinked. I tried to unkink it to the best of my ability. I called 1A and they send a new radiator, this one was ok. They also sent a shipper lablel send the first radiator back. It would of been best not to have a problem but, they have corrected the situation. Overall I'm pleased with the outcome !!!

Honda Civic
May 1, 2020
The radiator showed up on time and worked too well. Once the radiator built up the proper pressure it blew out the water pump or head gasket so I ended up donating the car. This was NOT a reflection of the A1 Auto Radiator, but the car was old and bad luck. I still highly recommend A1 Auto, fair price, fast delivery, quality parts.
