[V6-12v] Temperature Blinking Icon

[James Whitehouse]

Hi Casimiro,

Only just picked up this thread, but I believe Tom's referring to the coolant bleed valve for when you drain/ replace coolant? If you look in the engine compartment up behind the engine on the baulkhead there are two coolant pipes, almost central, quite high. One would, originally at least, have had an allen key bolt, as Tom says. However, these were notorious for the allen head stripping out so it may be rounded off inside, or may have been replaced just by an ordinary bolt. As a desperate measure, bleed by undoing the hose clips on one of the pipes then burning your fingers putting it back on - or better use some of those silicone heatproof/waterproof gloves you can get now! The V6 is a PITA to bleed through but it's important to get the airlocks out. If you get really stuck, let me know and I'll email a diagram.

Rgds,
James

Thank you for the information.  For the life of me, neither my son nor I could locate that drain valve.  He took "car tech" in high school and thinks he knows everything.  We looked from the top of the car as well as from underneath.  I have drained coolant from engines before, but this engine just stomped me.  However, we did follow what you said about letting the car warm up without the filling cap on, until the fans kicked on.  All this time the light was still blinking.  My son took the car for a short drive and the light did not blink; I guess it reset.

So, now I have a car with no heat, but one that I hope works.  Since this is a station car, I very much do not care about a/c or heat, it is only a half an hour drive and all I want is for the car to last for the next 20 months.

Again, thank you very much for your help.

If you didn't bleed the system after bypassing the heater core, you should probably do so. First remove the reservoir cap. The bleed screw is located in the hard metal line behind the drivers' side head. There's a plug that you unscrew with a hex key. Unscrew this 1-2 turns and leave it open until coolant comes out. Tighten screw to the specified torque (10 Nm I think, might be wrong). Start engine (still with the coolant reservoir cap off) and let it run until the fans kick on once. Add coolant to the reservoir as necessary. Once the rad fans kick in, fill the reservoir to just below the MAX line. That should take care of it.

The engine is probably fine.

Guess what?  My wife tells me that the light was blinking all day Friday when she drove to work, and back, 26 miles total.  I had told her to disregard the steam coming inside, so she took this to mean to also disregard the blinking light.  I flled the water container and it has not gone down, but the light still blink.  Could there be air trapped inside, not letting water get to the engine?

This motor may be cooked.  It still starts and everything, but  What do you people think.
