Towing Capacity - Toyota Hilux 4 Runner

[Shenoa]

Hi

I have a Toyota Hilux 4 runner - only a 2L engine, 1984, and I don't know what it's towing capacity is. I am hoping to pull a horsefloat and horse - probably around about 1600 kg. Does anyone have any idea whether this would actually work? Unfortunately the vehivle was sold to us as a 2.7 L but we later found out it's only 2.

thanks
