I am getting ready to install a KB 2.1, and trying to figure out a couple small problems I have before I get down to it. Here goes:
1) At startup, there is a hissing noise from the intake area. I have checked all vacuum lines ect, but it almost sounds like it is coming from inside the intake manifold. It is only present until it warms up, then gone. Anyone have this issue before, if so, what was the fix.
2) Radiator fan. The fan just doesnt work. I have checked and there appears to be power, and the fan turns freely. The Ford tech believes that it may be the relay/sensor, but you can only buy the entire fan/housing/relay assembly as one. I stay out of stop and go traffic because if I sit too long I can watch the temp start to go up, as soon as I start moving, it is right back down. I saw a writeup at one time about a way to wire it to stay on all the time, but I cant find it anymore.
3) A/C. Part of it is because of the radiator fan, when I stop for any amount of time, the A/C goes warm, as soon as I start moving, it starts blowing cold again. I attribute this to the fan not blowing air across the condenser, is this correct? The A/C compressor also makes a terrible noise. It almost sounds like a S/C at times when driving. At idle, it makes a loud moaning/whirring sound and drops the idle down to about 400-500 when it kick on then the engine compensates. Would you think this is the A/C clutch or the compressor itself since the compressor is still working fine other than the sound?
Thanks in advance for the replies. If I figure out anything, I will be sure to put it in.
