Howdy folks, I have a '02 1.9td. My temp guage dosent work, it comes to life maybe once a month. I've read through a lot of posts and a "temp sender" was mentioned alot, where is it in my van? Will this solve it? Could it just be a loose connection? Where should I check? Not sure whats what when I open the bonnet. If you have any advice I would really appreciate it.
