Engine gurgling sounds?
Engine gurgling sounds?
So I was driving my FD around for about a half hr or so, cool night, 60 degrees’ish, but when I got home and parked it in my garage after it had been shut off for a few minutes I heard a gurgling sound coming from the engine bay. It almost sounded as if the engine coolant was boiling. Temp gauges were within normal limits, but what could it be? I know it’s def not normal
IMO, it is normal, especially if a stock or near stock car. I have owned my FD new since 1994. This happened almost every time I stopped the car after a longer drive for over ten years. Only after modifying the radiator and pressure cap years later did it stop.

It probably is locally boiling the coolant, especially if the 13-psi radiator cap was installed. There was a recall in ~1994 substituting this for the original higher-pressure cap in order to make the coolant seals and, IIRC, the turbo coolant hoses less prone to failure. That is normal, especially if the lower temperature FC cooling-fan switch is not installed.

I’ve read about the fc fan switch on here, sounds like I should go that route soon, I haven’t heard about the radiator cap, I have a 92 FD, should I look into a different cap?

I've been running a 13-psi cap forever and it has caused no issues. If you change to the FC thermoswitch, almost all the gurgling /boiling will be gone.
