Thottle Body coolant lines

[CanVan87GN]

Just putting this out for opinions. I live in a climate that is hot in the summer (usually) and cool in the winter (sometimes very cold). Could you put a valve on the coolant inlet to the thottlebody to let the hot coolant in to warm up the throttlebody in the winter and shut the valve for summer driving? Has this been done already? Seems like a good idea for GN's that are daily drivers in the northern climes.

Yes this is right....I live in NY. so I do the same.

Another way more trouble but then it's only twice a year.
Is to get ATR's blockers..... And remove after summer.

Have one of each in my 2 cars....But the GN doesn't see winters.

Hope this helped!

Thanks guys. RobV6, stevemon, both replies are great. I was just thinking about the lines and it seems like a smart idea to me. Unfortunately my car is for business and I have to run it year round. The temp in the winter usually doesn't drop below freezing (or get snow) here in Vancouver but it can get cold. I see heating the TB to be the logical way for smooth cold weather starts. Once again, Thanks

Here is an opinion, even though we never have a need for a heated TB.

Just disconnect the TB lines from the heater manifold and tuck them under and away. Get a piece of hose and connect the 2 nipples on the manifold. Winter comes, remove the little line and reconnect the ones from the TB. No troublesome valves to deal with!

I ran the lines for 11 years and now have run no lines for 4 years or so.

No difference.

In a snow or ice storm you are always warming up the car whilst scraping anyway, it'll run just fine.

When it is just freezing out you normally let the car warm the oil and build some pressure, 1 minute or so works fine.

Just loop the line and leave it bypassed.

Just throwing this out there for the sake of discussion...
Do you really think disconnecting the TB coolant lines makes any difference on a "street" car?
I would think that having them connected would actually be of some benefit. Consider the actual heat soak from the block to manifold and to the TB. I would think it would actually run cooler with them connected and 160 deg coolant flowing through it, vs the heat soak temps of the disconnected way.
Now I am not talking about race track outings, where you are cooling down between runs and icing the manifold and TB to try and squeeze out another couple of 10th's, just daily drivers who like to play.
