The core probably needs to be replaced if it was disconnected because it was leaking. Normally that is what people do instead of fixing it. You can ddrive it like that if you want as long as hoses are by passed in engine. We don't have the navara in US as it's a right hand drive. I'm sending for a pickup here in US which is similar to your truck except LH drive. Removal would be similar as dash has to come out.
