Over the winter I ended up rebuilding the top end of my 1FZ, its supercharged and had always seemed to run a little hot during the summer months before. So while rebuilding I decided to try a TYC radiator that seemed to be raved about its cooling abilities, I understand it's a cheap radiator but figured id try it out. The days are getting hotter now and it seems to be doing the trick to be honest I rarely see above 200 now.
Anyways my issue is when I park the truck and come back to it in the morning or after a day or so there is a small puddle of coolant on the ground on the left side towards the lower rad hose (looks like its coming from there), I think the cooling system is building up a lot of pressure because the rad cap I'm using isn't allowing for it to release any... I running a OEM toyota rad cap.
Everything else seems to be functioning well. When I check coolant levels they are still very high and its only leaking a little bit, when I pull the rad cap off you can hear a woosh of pressure being released.
Just wondering what all you AZ guys are running for rad caps on your TYC radiators...
