I have a cooling problem which (seems to have) started with a busted bypass hose on my 87gt 5 liter. I replaced the hose, refilled coolant and still had the problem so I replaced the thermostat.
The problem continued, and since it only seems to occur under a load, I replaced the fan clutch. The fan would easily spin by hand after I shut the car off right before it was about to overheat. The new fan clutch does the same exact thing! According to what I've read in postings from this group, is that not supposed to happen?
Thanks for your help!
