About 35 years ago I did a modification to our Austin 1300. It had a plunger on the dashboard to operate the screen washers, and the bonnet jets always froze up in winter. So I got a few feet of plastic tubing, wound it round the top radiator hose, wrapped it in insulation and connected it into the washer feed. Bingo, heated washers that didn’t freeze up.
So why is it that a £35k car today has washers that freeze up at -3 degrees as they did today. Even with plenty of additive in the water? And with then recessed below the bonnet? I know some cars have heated jets to overcome this, but why not utilise the waste heat from the engine in some way. Am I missing something obvious here (and should I patent it...)?
