Cooling Question
1996 convert.. 5.3L . ? if fans should be coming on earlier???
Rad area is free from leaves. Had the cooling system flushed and new thermostats replaced 2 years ago.
Senario....(car in park)
A/C off.
Neither fan came on until 230F (digital readings) and both off again when it reaches 220F. Then low speed.
It cycles between these 2 temperatures.
I turned the engine off at 230F and both fans turned off.
??? Should not one of the fans stay ON????
Restarted the car and turned the A/C on. Both fans went into HI speed which started to cool the temperature quickly down to approx. 200F.
Question : Should not one of the fans be on all the time except when the car is traveling more than 30MPH????
Is this possibly a relay problem or something else??
Any help would be appreciated.
Thanks
Bob

If you search the forum, you will see lots of threads on "car running hot" or similar threads on the subject.

If your system is working the way it's designed, I don't see any point in driving with the A/C "on".
All your gonna do is wear out a lot of equipment before it's time.
pcolt94 explained the 95 system as it operates.
Just my opinion, but you'll have to get used to the operating system of the c-4.
If you plan on keeping it? Get yourself an FSM.
Again, it's just my opinion
