Gaurav Posted January 15, 2017 Report Share Posted January 15, 2017 My Pajero on some occasions heat up by 15-20% in off-road while self recovering or doing some extreme hill climb at 5-6k revs and then drop down pretty fast in few minutes. I was thinking of installing hood louvers and someone advise me that I might face some issues with RTA in next car passing by cutting down the hood. Appreciate if anyone have done this mod can share their experience if car got passed in RTA testing in Dubai with the hood louvers installed or not. http://hoodlouvers.com/shop/powder-coated-black-reg-flow-2/ Let's root for each other & watch each other grow.

Danny Posted January 16, 2017 Report Share Posted January 16, 2017 I personally don't think that will be an issue, as we see 100's of ricer and offroaders daily who have already done that. Only thing I can think is it should be done professionally and should be 100% safe installation as RTA majorly looks for safety concerns. Link to comment Share on other sites More sharing options...
Rahimdad Posted January 16, 2017 Report Share Posted January 16, 2017 (edited) Better to buy and install the hood from a Pajero Turbo Diesel which will not cost you a lot and store your original hood with Barry if any passing issues. In my opinion it looks good and more chances of passing since this is originally installed by Mitsubishi. Gives a great look to the car and should solve your purpose.

Gaurav Posted January 16, 2017 Author Report Share Posted January 16, 2017 Thanks @Rahimdad for suggestion, but I need two and both facing backward to let hot air exit. Above pic seems more like an intake than exhaust. In my engine bay in current place manifold is sitting right under the hood, leaving no space for hot air to exit.

desertdude Posted January 16, 2017 Report Share Posted January 16, 2017 You can always try the local shabab method of putting in a few nut spacers in your hood latches ( Can't remember if your capsula already had that ? ) which will raise your hood from the rear. I had it done of my sheep if you remember. I dunno about cooling but it kept the engine bay damn clean Link to comment Share on other sites More sharing options...
Gaurav Posted January 16, 2017 Author Report Share Posted January 16, 2017 I already tried that on my mechanic advise and yes it helped to a great extent that in Liwa it only popped up the gauge once in whole 113 kms offroad. However, it doesn't look very nice to my eyes and that's why I am thinking of hood louver option. Btw my SWB patrol had hood louvers too, but RTA wasn't very strict in those good old days.

desertdude Posted January 16, 2017 Report Share Posted January 16, 2017 Agreed it does look shitty, although I don't hood lifts and louvres will fix your low speed heating issues as mentioned in the OP. You just don't have the speed for air flow to expunge the heat. Also just a though this extra heat could also be caused by transmission fluid heat specially if your tranny cooler is merged into you radiator, if that's the case try with a auxiliary atf cooler first. Because both scenarios described put extra load on the tranny. Link to comment Share on other sites More sharing options...
ethan Posted January 16, 2017 Report Share Posted January 16, 2017 In almost all my cars I had these louvers. It comes with hood louver from the previous owner and never had an issue in passing. I think what Danny mentioned above makes absolute sense that as far as job is neatly done which is safe your car and other road user then RTA has no problem. This failing story must be circulating in market when someone get the sub standard job done. 1 Link to comment Share on other sites More sharing options...

Thanks @desertdude for tranny heads up and I think you might be right too, as in one of the instance while climbing fossil rock area from center (beaten up track), gauge started rising but I continue as I was done by 90% hill climb and when I kept continuing the climb, after reaching on top A/T light came up too, which usually never popped in last 6 years. Any ways too 100% check if A/T cooler need change or an upgrade? Let's root for each other & watch each other grow. Link to comment Share on other sites More sharing options...
