thinking of getting double layer too. Can I install the 1.6 wider radiator on a 1.5? will that has better cooling? cos I don't know what is the current condition of the fan and when they will break down :-)4 months. then change to samco. haha. i change it when i swap to double layer radiator. the previous single layer radiator from my 1.5 auto not that effective after swap to 93. my swap was not done properly btw. i did a lot of fixing and minor mods after the swap.
