Stupid question

[green73]

If I take off the two hoses that come from the dog house to the heater boxes and plug the holes will the car run cooler? I dont need the heat as its already in the 80s here

no it will run hotter. Take the tubes off and plug the holes in the bottom tin peice where they went through. If you dont heat will rise up into the engine compartment.

Or just plug the holes in the fan shroud with baby food jar caps. Guess they fit well and snug.

Then install your heater hoses so no heat get's in the engine compartment. No heat but still looks stock.

just plug the holes and dont worry about it.

Haha yeah that right to left was a bit hard getting used to lol! We got ACE I have looked at every car part store and hardware store for new hoses and cant find a thing so I thought it might be better to just stop the holes up. I caped the dog house holes with jar lids and filled the bottom holes with big tin foil wads for the time being

The original VW idea was to completely seal off the engine compartment into two sections, a bottom and top. The idea is to keep all the hot air beneath in the lower section where it will be pulled out behind the vehicle as it goes down the road. The top section is supposed to keep cool air inside it, cool air that is supplied by the vents under the rear window and possibly on the lid.

Of course dune buggies and many aftermarket shrouds don't follow that idea. Many have taken huge portions off the rear ends of these vehicles thinking that the greater open area will provide better cooling. They don't take into account that recycled hot air doesn't cool as well as cool air.

If you don't keep your heat exchangers sealed off from letting hot air enter the top engine compartment then you are comprimising the cooling system.

Another original idea by VW was to provide plenty of air to all the parts on the engine that get hot. The hotter they get the more air they need so the more air is directed to these parts by the OEM shrouds.

If you take off the heater hoses but don't plug them then you are allowing air to "leak" and your engine won't be getting enough air.

If you still have the heater boxes in place then you can't remove the hoses. The heater boxes needs the cool air blowing over them to remove the heat or your heads may overheat. If you remove the heater boxes and replace them with J tubes then you can remove the hoses and block off the outlets on the fan shroud but it's recommended to have a 1.5" hole in the plug as this creates the same back pressure as connected heater boxes do. You do not want to change the cooling characteristics inside the fan shroud - it far more complicated than it appears.

No problem.

Just make sure engine is put back as much to stock with seals and all engine tin so it is all sealed up. Any hole you can look down in the engine compartment and right down to the road is an air leak.

By posting images of the engine in question can allow all here to point out potential problems.

would be nice if someone made 2.5" discs that can block off those
rear tin bib holes...... , im cutting them by hand , a pita.
the caps make an easy regression path..

and j pipes with the heatwrap will send all the heat , to the guy behind you.
and not your heads,..
cheers.

As for plugging the fan housing use a 1-7/8 Freeze plug (Brass) East coast terminology or a 1-7/8 (Steel) soft plug west coat terminology.

I like the Brass look and on a persons seasonal choice they can be swiveled out for the cold weather and heat needs and reinstalled during the warmer weather.
