986 whizzing coolant

[Steve Tinker]

Eltren, as you probably know, the immobiliser CPU is located below the drivers seat - if it has been flooded, then the minimum you have to do is remove the seat and disconnect the immobiliser. You may be lucky and find the internal fuse blown, but as it has been immersed you will have to dry the immobiliser out completely - but I suspect you may have lost it.....This new problem is far bigger than fitting a replacement coolant pump.
Big dollars I'm afraid - I'm sure that someone on the board will chime in with an approx $$ cost.
It would retail at about $3 million here in Australia, but you guys get it a lot cheaper in the US than here !!!

It was in fact the coolant pump.
Replaced, ditto 4-way hose, ditto thermostat, ditto serpentine.

Total PITA, but gratifying.

Been blowing hot air on the immobilizer with a hair dryer for days.

It fired up on the first try.

I let it run for a while, pouring coolant the whole time.

Turned it off.

Wouldnt start. Everything looks good, just no starter.

Disconnected the battery for about 5 min.

That worked...a couple times.

And then it didn't.

Ideas?

Did you keep pouring coolant into the car? Or did the car keep pouring out coolant?

I am thinking the prior. However, I don't understand why.

Was pouring because the cooling system was empty. Fill the reservoir, let it belch and fart for a while and such down coolant, fill and wait some more.

The repair -so far- seems shockingly tight and competent.

I will pull the seat tomorrow, do the connectors at minimum.

It's idling in the driveway right now.
