In 1990 I had a new Ford F150 that I purchased grill blocks for use in the winter.

I purchased these through Canadian Tire but can't find the name of the manufacturer. They were a great product as they were a flat pieces of hard plastic contoured to fit the grill openings with basically U shaped pieces of plastic behind them. Each leg of the U shape had a tiny lip on the end.

You simply compressed the U shape slighty to allow them to go through the grill opening. When it sprang back from the tension, plus the lip, it was held firmly in place.

It allowed you to easily install and \or remove if overheating.

It was a good design people might want to replicate .
