I wanted to let you all know that you SHOULD NOT buy the Mishimoto aluminum radiator if you have a D16Z6 motor. Although their website states that the radiator is a "direct fit" for the D16 it isn't. The upper and lower radiator hose mounts are sized for a B motor not a D.
That means that the upper and lower hoses are 32mm (1.25") inside diameter instead of 28mm (1.125") inside diameter. You cannot stretch a hose to fit....I tried.
I called Mishimoto and they said that they know about this issue and that they are sorry. They did offer to refund the radiator purchase price once they received the radiator back. So, I am not out of the money...just time.
I wanted everybody to know that they should steer clear of this radiator if they have a D series motor. It appears that the fitment issue is due to the fact that the B series has 32mm upper and lower mounts on the engine side and the radiator side. The D series has 28mm mounts on the upper and lower engine side and radiator side. :bash
Other than that difference everything else fits. The radiator shroud fits. The fan fits. The coolant tank fits. The radiator cap fits. The radiator even fits between the engine block and the front frame mount although it is a squeeze as the Mishimoto is almost 3 times as thick as the stock radiator.
The only things that do not fit are the hoses.
This may seem to be a small issue...however, you can not purchase a radiator hose that has one end 32mm and the other 28mm. You can try to fit silicone hoses and stretch them out to fit 32mm. However, under pressure the silicone will split and fail. You can also try to fit a 32mm hose on both engine and radiator sides but the hose clamp will not hold when you reach the operating pressures of 14-18psi.
The Fluidyne, Mishimoto, Godspeed are all built for the B series and as such have the 32mm hose diameter. The Godspeed site says that they have a radiator specifically for the D but they say the measurement for the hose diameter is 32mm or 1.25" when it is actually 28mm or 1.125" So, even they are wrong. I checked with Honda and their stock radiator is 28mm or 1.125" Anything bigger and the stock hoses will not fit the thermostat housing or the upper radiator support housing.
The only other option I know of for an aluminum radiator is the Koyo replacement radiator :clappy. It IS a stock fit radiator. It has the correct upper and lower hose diameters. However, it is at least twice as expensive as the Mishimoto. So, if you want an all aluminum radiator with the correct hose size you can buy the Koyo for $400 :eek2 or the stock one for $65.
If anyone knows of another radiator that is all aluminum and has the correct hose diameters please post the manufacturer and purchase information. I still want a new radiator but cannot find one without this problem.
