Workspace.EnergyGrenade.GrenadeHandler:43: invalid argument #3 (Instance expected, got Vector3)?

ok so i think i figured my last post out but in the process of doing that i got this error

Workspace.EnergyGrenade.GrenadeHandler:43: invalid argument #3 (Instance expected, got Vector3)

the section with line 43 is

	local explodeCoro = coroutine.wrap(function()
		wait(explodesIn)
		local explosion = game.Workspace.Models.GrenadeBoom:Clone()
		explosion.Parent = clone.Position --line 43
		explosion = clone
		clone.Explosion:Play()
		clone.Transparency = 1
		clone.Trail.Enabled = false
		wait(3)
		clone:Destroy()
	end)
