Hello all!

It's pretty hot here in Indiana and I just got done replacing parts to fix a cooling issue. Was just wondering about how long the main cooling fan usually stays on before cycling back off? On my previous vehicles it would take about 30 seconds but on my 95, it can take a while, sometimes upwards of 5 minutes. Is this normal?

CX radiator, Mishimoto fans with shroud, factory coolant routing.

Thanks!

 

It's not time based it's based on the coolant temperature. We can't tell you if it's normal without knowing what temperature the coolant is at when the fan turns on and off.

 

Right. The factory ECU has a set "on" temperature and "off" temperature. I guess what I'm trying to ask is how long it takes most cars to go from on to off .I know this will vary drastically based on different outside temperature, ducting, radiators, fans, etc. Just trying to get a general idea. I know most everyone here has MS running the fans so I may not get an answer

 

Mine: 2000 factory ecu, factory routing, factory T-stat, China aluminum rad, stock fans ganged together. Stationary cycle on to off in 80F ambient is between 30 secs to 1 minute at idle.

 

Wow that's fast. Makes me want to pull the trigger on grounding the fans together at the ECU
