lumpy Forums Junkie Location: Adelaide, SA Registered: May 2002	Re: 1jz ma70 overheating when air-con running Sat, 21 February 2004 13:36 Ummm... the following is a bit embarassing I had the harmonic balancer replaced, as well as the water pump/engine fan pump on Friday (the water pump was a BIG job - you virtually have to take the timing belt off to get to it) When the mechanic (manys thanks to Greg - absolute champ!) put all the harmonic balancer etc back together he noticed the fan wasn't pushing much air. We bled the fan pump etc, but it didn't really help. So I compared my fan output with another 1jz conversion and his fan was pushing heaps more air. We were trying to figure it out when he said "It's like the fan control computer isn't working" - at which point I thought "what f**king fan computer"!!!! I couldn't recall installing it...... apparently it controls the fan speed on the 1jz, increasing as the temp increases for more cooling effect. D'oh! Then, just as I was thinking where I could get a computer from, a fellow Supra owner (Danny T) found it still attached to the dashboard from my half-cut when he was looking at some of my parts for sale!!!! Now I just have to wire the bloody thing in. Also, I may need to change to a jza70 radiator since my Cressida radiator is missing a sensor in the bottom of it. Is this important to the fan control, or does it take it's input from the thermostat? Whoops! I was so proud how neat my conversion is... [Report message to a moderator]
