So i want to get a really good aluminum rad like a Koyo or something but their site says they dont make one for a 4runner which isnt a shock. But couldnt i send in mesurments and get one made to fit? Love these rads, friend has one in his sr20'd 240 and its real nice quality and its runs super cold all the time.

I just picked up a used 3vze for cheap and my rad is clogged so i figured im going to go with an awesome rad and make it run real cold. Any ideas are welcome

 

The stock radiator is more than capable of cooling the 3vz. I got a replacement from Napa a while back and have zero complaints. Most places sell an OEM style brass/copper unit and an updated aluminum unit...I opted for aluminum.

 

Most reputable radiator shops can clean your existing radiator for far less than replacing it. If you want it to run cooler, why not just put in a lower temp thermostat?

 

There are better things to waste your money on for no gains

 

Exactly lol.

And you don't want to put a colder thermostat in a fuel injected vehicle. If it never reaches expected operating temp, it will never make the change between open/closed loop.

 

Just thought it might be a good idea since this things lovea to get hot, a nice aluminum rad with a couple electric fans to keep er real cold.

I think koyos go for around 300 bucks anyways? New from napa was 190?
Plus koyos come with electric fan included.

But yeah maybe just grab a cheap one and taurus fan it.

 

I don't remember what the brand was, but I put a full metal radiator replacement in my veezee after she blew up the old rad on I-5 stuck in traffic... ran about $300. stock radiator is more than adequate as stated earlier. My explosion was from neglecting a slow coolant leak and idling in the hot sun too long like that. oops!

don't forget to get some Zerex asian vehicle coolant while you're at Napa, it's the same as Toyota LL coolant at 1/3 the cost! $11 and change for a gallon unmixed

 

You can get an aluminum radiator on summit racing for pretty cheap. Just go take some measurements, get the orientation of the inlet/outlet. And the diameter. I had one figured out for under 200 bucks, but I lost the link. I'd have to do the research again

 

You can also have your old one recored at a radiator shop. We use pacific cores from canada,awesome quality. Thicker materials,tubes are swagged the best I've ever seen,extra solder built up around the tube to header joint. You can get a PC 3-row core which is basically an exact replacement (I'd say it's actually built better than factory toyota) or a high efficiancy TQ 2-row core that is 1 5/8'' thick as opposed to the Pc 3-row core that is 2'' thick. Thicker isn't always better. The PC 3-row is 3 rows of 1/2'' tubes,and the TQ 2-row is 2 rows of 3/4'' tubes for more tube to fin contact. You can gain more cooling by ordering it with a higher fin count (up to 16 fins per inch,13 standard) and getting it with dimpled tubes to slow the flow down a little. It gets pricey,but you will have a new radiator (essentially,other than tanks and side brackets) that is put together better,with more solder than the factory (if your radiator guy is good anyway) and a higher quality core than the factory. It will also be easier and cheaper down the road to repair than aluminum,and not as finnicky as aluminum. You don't have to worry about electrolysis as much either. In a 2wd I'd be more likely to run an aluminum rad (I do in my camaro) but 4wd is more likely to need repaired. That's just the opinion of a radiator repair guy that sees this stuff 5 days a week.

 

Ok so the word still stands just go with a basic replacement rad. Cool stuff turd! I think i understand a bit ha ha maybe i will just get a napa rad and some of that coolant too and just let it be. Any tips on electric fans? Or just taurus fan mod?
