Houston we have a problem! Bought a radiator for 1998 Honda CRV. It all bolted up nicely and I’ll trust that the said quality improvements hold up. However, somebody mis- measure the radiator inlet design. Radiator comes with no new radiator cap. The old one would not fit. I mix’s them and the new inlet was 2 mm larger than the cap. Same story at the auto parts store… all caps were 40mm and inlet is 42 mm!!!! I had to by a 93 Honda Accord cap to make this work as it is also a deep well type cap, the radiator inlet is deep well, standard caps are not!!! This needs some serious investigation or sell it with a cap that proper.
