Gurrgling Coolant

[scruffboy]

When you first start a Supra MK III, should you here a gurgling sound in the dash (I assume heater), or is this a sign of problems? Any help would be appreciated.

Thanks,

Pretty common problem. It CAN be a BHG but more than likely you just need to burp your cooling system. Here's a link from Suprra Girl

Also mrnickleye suggested once, and I can't remember where I just know it was him, to cut the dangley thing on your thermostat and bore the hole out to 4mm to help reduce this problem in the future.

Thanks Murd,

I'm pretty sure no BHG but I'll chek on how to burp it, thanks.

For anyone who needs to bleed air out of their coolant system, the easiest thing to do is to get a coolant fill funnel kit. It is pretty inexpensive, and you don't have to go through the same process that Suprra girl went through. This is a one shot deal. Anyone want to know how to do it, shoot me a pm. I'll be happy to explain.

At the SupraGirl site I read this quote "***note... water WILL pass thru heater core when thermostat is closed, (on a cold engine)****". So is what's happening normal on cold start? After the engine warms up all sounds disapear. This has just started to happen as the temperature here dipped a little in the mornings (I get up real early).
