Had a few issues with fit
The Frienda cap works well, but it didn't fit my radiator quite as snugly as I hoped. It’s functional, just a bit loose compared to my old cap. Still, it’s better than nothing!

Great value for the price
The Frienda coolant reservoir cap is a fantastic deal! It fits like a glove and doesn’t leak at all. Just what I needed to ensure my coolant stays where it belongs. Highly satisfied!

Not impressed with quality
I expected more from this cap. After just a few weeks, it feels a bit flimsy and I'm unsure about the seal. Had to keep an eye on my coolant levels, which is not ideal. Disappointed!
