My Grill Block

[CKaelin]

Check it out guys... Whatcha think should I do the bottom aswell?

[KCALB SIRAY]

better than some I've seen, nice job

[rningonfumes]

Nice!...I just went with the cheap and easy and used black duct tape. Of course, the sedan's top opening isn't as large as the hatch's so it was easier to just use the tape.

[CKaelin]

Materials I used were as follows. This floor matt type thing that is foam like and plastic zip ties.. Had both at work. Free. So should I do the bottom opening aswell? I was thinking I'll wait till it gets really cold. See how it goes with this setup for now.

I wouldn't do the bottom unless you've got a scangauge so you can keep an eye on your engine temps. Wouldn't want to damage the car

+1, are you running this currently? Keep an extra close eye on your temp.

I am using it currently. Just made it yesterday. It's been getting cold!

[smofskra]

i drove my yaris all winter last year with no block and had no problems at all. keep in mind that im in north central wisconsin. it gets pretty cold here and had no problems with it at all.

You shouldn't have any problems. The point of the grill block is to make the engine warm up faster and stay warmer. I'm sure BailOut can give you the numbers, but in theory it should help improve your fuel economy in the winter months.

[Thej3sta2]

man if you would have found some way to tie it without the zips it would look pretty sick.

[YarisDude]

Great job, looks very professional.

Someone mentioned in a previous post, to loose the zip-ties. I used Velcro to fasten my block. Makes it real easy to remove in the summer or on the rare hot winter days....push-on & rip-off!

Hmmm .. but doesn't it block a bit more airflow to your intake which you want?

It's understandable in terms of warming up the engine, but I'd personally take airflow over warming your engine up quicker. Lol what, can't get a remote start or start your car 10 min before leaving?

[Sodium Duck]

Starting your car 10 minutes early would waste gas. You should read, too. This isn't a performance mod obviously, however I doubt it would make any noticeable difference in power.

As I said before, the grill block helps the engine warm up faster, and stay warmer for longer after you turn the car off in case you will be starting it again shortly.

Your engine can't always keep itself warm, and when its temperature drops too low your ECU starts feeding even more fuel into it in order to force it to run at a higher RPM in an effort to generate more heat.

In order to stop this wasteful cycle many people block their engine grilles in the colder months in order to stop the flow of too-cold air into the engine area. My own rule of thumb is to block the upper grille when daytime temperatures are peaking at 65F, and also the lower grille when daytime temperatures are peaking at 55F. I also use an engine insulation blanket once daytime temperatures drop to 45, and I will post a DIY on that when that time comes.

Another lovely BailOut quote. Yes, it does waste a lot.

Doing something like not idling for an excessive amount of time, or turning your car off at lights isn't ridiculous, it's really simple and easy to do.

Bassically, if you don't want to do it, then don't and stop complaining about it. Or search before you post, so you actually know what you're saying.

I'll be making a winter front this weekend. My car JUST hits operating temp (86) as i role into the parking lot at work. (25min drive.)

[stuffy]

hmm...might think about making one of these.

glad i read this, i was confused as to what the purpose of a grill block was. i thought it was for aerodynamics!
duh

This is a Fuel Economy Forum broseph..

So this whole conversation got way off topic...

I think I'm going to make a grill block myself, too. Whoever was using the velcro to hold it on, how's that hold up? You think a couple feet of snow and some highway speeds will take it off?
