Hi everyone,

I'm in the middle of changing the cooling system up in my hilux, It has a 1jz vvti out of a jzx100, Currently using a slightly modified v6 4runner rad with 2 Spal 12" pusher fans in front and is just not doing the job!

I've found a 2000 MR2 Spyder 3 core ally radiator that with some mods to rad support will fit under the top bar on the rad support, core size works out slightly larger than what i currently have and will allow me to mount 2 12" puller fans inbetween the motor and rad with a shroud, Should end up very neat and will leave enough room that i can reinstate my aircon YESS as before the temp would creep 1 degree at a time whilst driving until i had to turn it off,

Going this route will mean the radiator will be lower than the engine and i will need an expansion tank up higher in the engine bay, Does anyone have experience with plumbing Expansion tanks into cars that never had one, I've attached a photo of where i think the large hose from the bottom of the expansion tank should go, But the other line from the top of the expansion tank is the one i'm not sure where to go with, Would i tap and fit an outlet on the top radiator outlet on the head near the thermostat? so hot fluid and air can go to the top of the expansion tank and then return to the "cold" side of the radiator (top of rad fitting circled in photo)

Going to delete my second battery for the moment and make a new aluminium airbox where the battery currently is and make the Header/expansion tank and mount it where the airbox currently is,

Also chucked a couple of photos of the rig to have a look at


Cheers everyone

Hi Mate,

Thanks for the reply, Are the 7m's shorter than the Jz's? There is no way i'm going to fit fans between the motor and rad on the engine side of the rad support at most i probably have 25mm at a few pulleys and one is around 10-12mm gap to the rad, How much gap have you got between your rad and the a/c condensor? apparently from what i've found about 15mm gap between them is ideal as it let cool air get in from around the condensor to go through the rad as well, can't believe how hot the condensors get though wow

I'm going to start a build thread today, I should have started one a long time ago, and will add in my findings with the Mr2 radiator and expansion tank as we go along

Yeah wow, getting rid of the water pump and ps pump frees up a bit of space great way of doing it, Back of my rocker cover is about 10mm off the firewall aswell, Will definately post up some pics of what i have to do, I've had the car engineered so what ever i do to the rad support will have to be able to pass engineering again if i happen to get it stickered for some reason, so will be well thought out and carried out!

Cheers
