S/C shutting down
I'm so confused, my car is stock other than a Johnson pump and a bigger heat exchanger. Yet, if I do one short full throttle run, my S/C almost instantly shuts off, my coolant temps are actually nice and low... so I'm confused why it's doing that.

If I let the car idle for a few minutes and get in it.. no S/C until I cruise for a bit and suck in some cool air, then, if I get on it, even for a sec, no S/C after that for a little bit.....


SO CONFUSED!

My car is the same right now, just ordered a new pump. But the current pump is only 6months old.
How do you measure your IAT?

Yes, IATS and what is the mileage on your car? Johnson pumps are also known for premature failure. Did it come on the car or did you install it?

get a OBD2 scanner and you can view the IATs under live data

if you are in the 199 range at WOT then you know the s/c will be shut off

Maybe you have air in the system. Did you bleed your system until it got rid of all the bubbles when you installed your HE and pump?

bleeding needs to been done right. There is a DIY posted, for your search.

You can't just let the car run and think the bubbles would come up to the coolant reservoir.

How is your ambient sensor? and also buy a cheap OBD2 scanner and measure your IAT's...

S/C shut down with out CEL is rare, usually is due to air intake temps.

If you have CEL, checks your plugs and wires first.
