Built me some hood vents
oh snap!, i LIKE those.i have seen a lot of hood vents?, and most all look exactly like what they are. someone cut a hole in the hood and slapped a soffit vent in it. functional sure?, but aesthetically unpleasing. and an awesome DIY write up too! bookmarked for future use and sharing. stoked, i do have one question (that applys to all hood vents) and that is...what about water/rain getting in?, is this just not an issue?. seems to me like doing this is opening up an entire new set of problems due to weather exposure. thoughts/comments/solutions?
If you read the entire thread, people actually commented about the water issue. We never put them in my FIL's Jeep and it's been fine for over a year now. Never a water issue. Never a weight of the snow issue either. I'm going to do mine with no drip pans too. I figured why bother? I go through puddles and powerwash my engine. What's a little rain gonna hurt? Glad you liked the thread. Make sure you post pics when it's done!
Oh, and you're very welcome.
Like I said, I don't have them in mine yet so I can't say. With the 2 fans set up I have, it runs at normal temps but it takes a lot longer to reach temperature. It helps that I run a 180 t-stat in there as well. I went offraoding over the weekend. It was about 85 degrees or higher outside and I had the AC running the whole time and never went above normal. Sometimes the fans even shut off because the temp went below 190. I've seen guys say that the hood vents help and others say they don't. It may have something to do where you place them on the hood. I'm not sure. My FIL's Jeep hasn't overheated at all. His runs at normal temps too. I think the thing that people forget is the radiator and/or condensor fins need to be cleaned. You could have 30 hood vents, a 180 t-stat, 6 fans in there but if the radiator and condensor are caked with mud or the fins are bent, no air flow can go through them. No air flow= no cooling.

I don't have any under hood temps to post, but it made a lot of difference. There is a hill here that many people commute up and down every day. I used to not be able to travel up that hill without blowing head gaskets. Now it stays at 195°

Thanks. WHat I was initially interested in was: I thought you had 2 fans in addition to the radiator fan - made me curoius as to where you placed the "third" fan. I don't need to modify anything (yet) because the heep never overheats. But of course now that I've said that ...
Good to know there's a solution out there.

Ah ok, I gotcha. I've actually seen a pusher fan installed in front of the condensor as well. Now you've got my wheels turning. I just ordered a trans cooler so an additional fan in the front may not be a bad idea. Time to go take some measurements. I'm not sure the stock fan will fit in the front. I will report my findings when I get them.
