Your engine bay has a lots of space between the header and the radiator fan. Can put one of those fancy extractors with long runners. Mine doesnt have such space

The fan in front of the header is actually the aircond fan. Even with this aftermarket header, the distance between it and the fan is still similar with the stock header+heat shield.

That actually happened once before. Melted one of the plastic legs off the bracket.Are you worried about the heat from your header damaging your fan?
So, did you change to a different type of fan after that?That actually happened once before. Melted one of the plastic legs off the bracket.
Is the melted fan a standard Proton unit or aftermarket? Is it because it melt due to top legs detached and the fan fell over? Or the heat broke the top legs?It was a one-off incident. Was caught in moderate jam at Pudu. Suddenly temperature shot up. Found a place to park and opened the bonnet. Top legs was detached from the main frame and the fan assembly fell over & was resting against the headers. Luckily there was a spare parts shop nearby. Walked over and bought a standard proton unit. Been many years since that and the replacement fan hasn't failed yet.
For an NA engine, there hasn't been a need to upgrade radiator/fan assembly. 4G93 DOHC heats up from cold start really fast. I believe this engine builds up heat easily but using Toyota coolant, engine temperature has been stable even when revved hard up Genting. Thus far, I only had radiator top panel replaced once. I believe turbo units may require better cooling.
Edit: Sanekit appears to have red colored aftermarket radiator. Looks slimmer compared to mine.
Edit2 Oops. The red color is not a radiator :stupid:
It was a standard proton fan. Came with the car when it was new. Don't think I can blame it on the heat of the header. The replacement fan has been in use for years without issues. Tbh, I cannot tell how the legs broke off. By the time I opened the bonnet, it was melting against the headers. Hard to pry it out since it was stuck.Is the melted fan a standard Proton unit or aftermarket? Is it because it melt due to top legs detached and the fan fell over? Or the heat broke the top legs?
Then maybe your headers should be fine although the gap between them and the fan is quite close. Just that melting incident happened because the legs broke off.It was a standard proton fan. Came with the car when it was new. Don't think I can blame it on the heat of the header. The replacement fan has been in use for years without issues. Tbh, I cannot tell how the legs broke off.

Are you thinking of upgrading your fan?
I support that idea. If it aint broke, dont fix it.it is managing the temperature quite well even when I am driving at near 6000rpm in 4th gear, I don't plan to change it now.
U need better heatshield.That actually happened once before. Melted one of the plastic legs off the bracket.
LOL. Radiator is not there. I'm using double layer long radiator as my car is auto. My headers comes with the stock heat shield.

Well, you are right. If it ain't broke, don't fix it. My mechanic did told me that if I want to mount a full sized radiator, I need to make some welding modification below to mount the right side of the radiator. Or maybe I can go for those Taiwan aluminum radiator which is available in half size.I support that idea. If it aint broke, dont fix it.
Original comes with a metal plate/shield at the front. I think it's to prevent the air from the fan cooling the headers. Wonder if I should get the exhaust fella to fashion one for me.
My SS muffler already 16 years, the rust from the welding area.......lolSS can rust a bit. And crack.
Oh damn. Extra charge.
My muffler oso SS. Damn dirty. Too lazy to polish back. LOL.My SS muffler already 16 years, the rust from the welding area.......lol
Autodetailer woh!
Yes, that's stockWhat 4-2-1 header is this? Stock 4G93 in your C99 Wira?
Now looking at your extractor, the 2 to 1 joint before the flexible bellow, does not look smooth/straight. A bit bent at an angle......Here's a pic of the header I replaced recently. Since my car doesn't have a 02 sensor, they welded the port shut.
Paid 250 for it. How much did it cost you, RENESIS?
The Hotbit's unit was 1-piece. Had difficulty removing it. I asked them to cut it into 2. This is also to prevent the old header from being re-patched and later re-sold.
