We’re on the same page there. The fan in the Malibu I had before didn’t kick on until 228F but I think that anything over maybe 205F is too hot... I need to research a manual fan button (and/or variable grille block) to keep coolant temps in check on the freeway... it stayed under 200F until I went up the first hill and stabilized after, but by the third it was heat soaked enough to not drop back down much under 210 for the remainder of my 40 mile trip

The worst I’ve ever overheated an Ecotec was my Redline on the last day I drove it... I had deleted the flap under the radiator that diverts air up into it, but didn’t duct the lower grille to the radiator like on my “Green Line”, and during a sustained high speed run to the hospital in 100F weather, I looked down and noticed coolant temp at 250F... I killed it immediately and coasted to a stop(from 85mph) and waited for it to cool down, and resumed driving, but at a slower pace until I could remount my cooling flap... I think the only reason I continued to drive after such an overheat was that the car had an MLS head gasket and ARP head studs clamping it

So, with all the time sitting, something was bound to go wrong with my car... the trunklid extension sagged from heat enough that the tape holding it on let go, and it fell off... thankfully I was at work and could pick it up but it’ll need revised all the same...

I almost got a 500mi tank today! It was only 10.44 gal, showing a hair under quarter tank, so I definitely coulda hit it but didn’t wanna drive around just for sake of hitting the number and didn’t wanna pay 15 cents more to get fuel in the next town... 492.7mi after tire size correction... with around 38 mi of commute at only an average of 38mpg dragging down my average, I feel optimistic that if I eliminate all of the really short trips, 50mpg would be doable...

So, I got some time to work on my car again, and decided to re-do my trunklid extension, this time making it as sag proof as possible...

Last time around my panel was attached to the edge of the trunklid and it had four metal tabs holding it on that were about an inch, I was basically relying on the coroplast to hold itself up...

This time I lapped the coroplast about 1.5 inch into the trunklid itself, and used five plastic triangular supports under the panel, extending almost three inches... I also made the extension about 1.5-2” longer than before, so it now extends almost 6” from the edge of the trunklid...

I also used a lot more strapping tape than before as I consider this closer to a finished product than the last one, hopefully it doesn’t fall off in the heat!

It is becoming quite the Eco-Ratrod.

What is causing this kinda cool looking clamshell wave pattern under the decklid spoiler?

I think it’s just because I used the cheap coroplast which doesn’t have a smooth surface... it has diagonal flutes inside instead of straight ones... free to me though

So how do we get the full size pics?

When you attach an image file. Click the link to open it in a new tab. Then copy the link location or url to your clipboard. In your post text, type [img] before the url and then [/img] after the url. No spaces or it will not work.

I grabbed a couple more pics to illustrate what I’ve done...

It’s about even with the bumper cover and about as far out as I’d like to go...


This one shows the support panels under the extension... I didn’t shape them right though... oh well,they work lol

I’m kinda stalled out on this project... I try not to drive it any more than necessary because my control arm bushings are awfully bad and I have new control arms ready to install... had to patch a tire because it went flat overnight, from 55psi, but haven’t done anything else...

I wanna make some wheel skirts...
