UPDATE!

Matt is letting me borrow a hood so I can work on bonding the cowl to my hood. Here's the $15 hood I'm borrowing...

140

Yep, that was the previous main reason I wanted to have something like this. Thanks.

Can I get the approximate dimensions of that skid? Maybe a picture from behind? No rush.

Also I'm assuming that it has sides.

So the reverse cow catcher wasn't enough to keep it cool?

Actually because of this picture (seeing it in the past) I thought about putting an electric fan under the cowl induction hood. 1000 CFM to suck the air out of the engine bay and push it out of the...

I had already considered putting a cable control flap on the back of the cowl just for those really really cold days.

When you say back to the axle you mean as far back, not as far back and down...

Well my understanding is that the cowl induction scoop allows air to escape at low speed like off road stuff, and at high speed it sucks air into the engine compartment.

I like the first part of...

Correction. It did NOT run hot on the highway for the first 9 years I had it. It started running hot on the highway after the 4.5" lift and wheels and tires were added.

It has over heated on the...

Yeah driving at highway speeds it runs a little rich. I'll have to collect new data.

Here is the BOOK that I've written if you are so inclinded. :link:

Readers Digest version...
All new hoses (lower hose with coil)
3 core all metal radiator
high flow thermostat
high flow...

Yeah it doesn't go very far back. Interesting information. I'll get a better picture of the underside and what I have in mind. I was thinking of placing a cover from the bumper back a couple of...

Yeah I moved the transmission cooler...

Would you think this would accomplish that?

It runs hot in cold weather as well. I call it heat creep!

I changed the temp sensor and it read higher! Turns out that about 90% of the stuff I was fighting was due to the new sensor displaying...

It's been running a little rich, according to the OBD II data I collected on my laptop. I changed the front O2 sensor a few months ago, and I need to check it again to see if the running rich...

Well could be I guess, but both clutch's had the same running hot problem.

I could always try the old one and see what happens.

No, no problem. Ask away I appreciate the help.

It's a Grand Cherokee heavy duty fan. I'd have to go back and check but it may be 2 years old now. It was another step in resolving the high...

I'm already frustrated with a problem that has been going on for years. I got sick yesterday and I'm not feeling very well so I should probably ban myself from the board for a couple of days until I...

This just feels right! :smiley-laughing021:

Yes I do understand the logic of this however please keep in mind that this didn't start when I added the bumper it was doing it, only worse when it was all stock with the exception of the lift,...

lol problem is I need to fix it before I take a long road trip like that! :smiley-laughing021:

As many of you know I've been fighting a "running hot" problem on the highway for years now.

I've made several modifications to the cooling system all of which have done wonders for low speed...
