98-01 4cyl turbo engines

[aaron...]

$10 fan switch you say huh?   So which one is that?  The one in the 
radiator?   (pulling up car part website as we type! )    I wish I knew 
that  two months ago when I put my new radiator in.   One would also 
assume that if  they saw their water temp guage get much past the half 
way mark that they should pull over.

'98 A4 1.8tq w/ mtm KO4 @ 123,xxx miles......rebuilt head @ 105k due to 
snapped t.belt.
