how do i tighten my heat shields on my 1985 volvo 740 gle
karmen, most of the time, either the heat shield fastener or the mounting hole has rusted out. So it depends on which heat shield "rattles" and what you will find when you have a look at it.
Heatshields are best thought of as alarm bells. If they are loose, then (IMHO) the car sounds like it needs maintenance.
Repair the heatsheilds by re-welding the join (its a small weld that you could probably do with liquid weld that is sold over the counter).
But look over the suspension, the shocks, the steering feel, and even things like the balance on the tires (an easy check and fix)
I've used large hose clamps before. Works fine especially if no welder is available !
