jgreg53 Posted February 24, 2019 Report Share Posted February 24, 2019 On the p15, what goes from the fresh air vent on the firewall to the radiator wall. Right now i have a dryer vent hose. Seems like there should be a square duct of some kind. Quote Link to comment Share on other sites More sharing options...
greg g Posted February 25, 2019 Report Share Posted February 25, 2019 The vent on the p15 is in the cowl. The operating lever is under the center of the dash. Never seen a p15 with an air opening in the firewall. Heater hose connections penetrated but not air. Can you put up a picture of what your set up is. Fresh air for heat defrost didn't start till 49/50, they consider mostly of card board ducting. The heaters elements for these systems were mounted pass side behind the radiator support.

jgreg53 Posted February 25, 2019 Author Report Share Posted February 25, 2019 (edited) I know about the cowl vent. This is an opening with a butterfly flap. Left side of the firewall near the heater hoses. I'll post a pic. Can someone tell me whar is supposed to connect this to the radiator wall? I have been using a dryer vent hose.
