Hi all, trying to get my car all sorted out and was wondering if anyone knows what this duct tape is covering up? There is one on the passenger side and another on the drivers side under the car near the engine. Is this something to do with the heating system? The heating system doesn't work and I know I will need to add parts like hoses and flappers, the car does have heat exchangers.

I'll do an experiment to test what Raby says. I'll take the covers I made off the outlets and see if it affects oil temp.

I'll do an experiment to test what Raby says. I'll take the covers I made off the outlets and see if it affects oil temp. The effect would be on head temps since the air blows over the heads and cylinders. Not necessarily on oil temps. Head temps and oil temps are not necessarily always connected. But that isn’t how it was designed. You're saying that it wasn't designed for air to flow out of the fan shroud all the time? Backpressure or no, air is still always leaving the fan shroud at those ports. If the HE's are connected the air travels through them and exits to the atmosphere anyway through the flapper valves if the heat isn't on, or into the cabin if the heat is on. There's always air moving through that system. Blocking the air completely will have negative results. But without a 4 channel head temp gauge to monitor all 4 head temps, you'd probably never know. Do what you want, but if it were my car I'd take Jake's advice and leave them open. Attached thumbnail(s) |
