E24 Fan Clutch

[Dogkip@xxxxxxx]

I live in Dallas, TX and continually fight the "running hot" problem.  
Problem only surfaces when in heavy traffic on a hot day. I have tried most 
everything... flushed system, new radiator, cleaned outside fin surface on 
condensing coil, auxillary fan bypass, wetting solution, removed center core 
of the thermostat.  My latest change was to run a couple of screws through 
the fan clutch to prevent slippage.  I noticed that even at low speeds, there 
was significant slippage, reducing air flow through the radiator.  Locking 
the clutch significantly increased the fan tip speed.   I had tried a new 
clutch, but noticed that there still was slippage.   My question is ... will 
locking of the clutch cause any other problem?  I realize that it will suck 
off some hp, but that is a small price if I can keep the temperatures down.

Also, any other things I can try? One of the biggest problems appears to be a 
very tight engine compartment and restrictive air flow through the engine 
compartment.  I was thinking of removing the rubber seal near the cowling 
just in front of the windshield to allow some of the air to blow out the 
louvers.  What kind of trouble can that get me into?
