Another IC pump question ?
Hi everybody, this is my first post !!!
Ok, here we go ! This is what I did so far:
1- Check IAT with OBDII reader, when car cold, ambiant at 20°C, IAT at 20°C
and after 10 minutes, IAT at 24°C, seems ok to me.
2- I know ECU disengage supercharged when IAT is above 93°C and that's my
3- Took out the IC pump, disassemble, clean and reassemble it. Plug it to a 12V
power supply, inlet in the sink and pump was working fine !
4- Put it back on the car, hook the pump with the same power supply (not from the
car battery or with OEM harness), pump is working but something strange is
5- My question is: when the pump is working that way, engine off, I should see
coolant coming out of one of the two metal pipe when I disconnect the rubber
hose that goes back to the coolant reservoir ??? No coolant comes out ???
And if my english is not that good it's because I'm a french speaking person from Canada !!
Hope someone can answer my question. Tnanks
