U20 Radiator switch onto R16 motor
Want to install a U20 radiator onto my R16 motor. To do this switch, do i just need the U20 radiator AND the U20 thermostat housing? Or is there more to it to switch over? Anyone out there done the switch?

Be very careful to not mount the U20 radiator too high as it may dent the hood when you close the hood if you are not careful.Stratman101 wrote: Sun Aug 07, 2022 7:54 pm Want to install a U20 radiator onto my R16 motor.

I have the u20 rad. As far as eliminating the r16 therm tower, i read another post saying i can replace the entire tower with a 240z gooseneck , drop in the thermostat and done. Agree?

Not necessary, but you can replace the R16 water tower with an L-Series unit:

Looks good Mike, I may have to try that fan in mine. Looks to be a copy of a Hayden brand.

Re: U20 Radiator switch onto R16 motor
Yeah, I think the two brands merged, or one's a division of the other, or whatever, but here are the specs, when I bought it in 2005:nismou20 wrote: Mon Aug 08, 2022 12:19 pm Looks good Mike, I may have to try that fan in mine. Looks to be a copy of a Hayden brand.
