Hi BC1207, you can record the loan using a liability account - if the loan is long-term (repaid in 12 + months) this would be considered non-current. To create the account, navigate to the Cog > Chart of Accounts > New > Select the relevant liability account and detail type on the drop-downs and enter the total amount in the 'unpaid balance' field. To record the repaying the loan, enter an expense (+ New > Expense) with the business bank account that the repayments were made from in the 'payment account' field and the liability account selected in the 'category' field, with the total amount entered and no VAT selected.
The purchase of the van can be entered with a separate expense. Firstly, create an account for the van (Cog > CoA > Select 'Tangible assets' as the account type and 'Vehicles' as the detail type, and rename if desired). Then enter the expense, with the bank account that the purchase was made with in the 'payment account' field, and the asset account in the 'category' field, with the total amount and relevant VAT code selected. 🙂
