I think Socha_62 got it. I had just been looking at the overflow tank and its full. Duh me. I popped the cap and sure enough it was low. I dumped in about a quart of coolant this morning, and now the sound has disapated (sp?) all day long. I'll try to remember to report back tomorrow if its gone altogether or what.

2M8 actually she's got a 350

 

when you fill it up it helps to have the heater on full blast...helps to circulate and may help to get teh air bubbles out...... if the coolant system isnt filling itself by the resevior .. then you may have a vacume leak on it.. or a bad rad cap...

 

I dont mean to jack the thread, but what kind of transmission do you use behind (beside?) that 350? That's gotta be a thrill ride!

 

Well after adding that quart of coolant the problem has nearly been eliminated after a day and about 30 miles. Maybe another day will work the rest of the air out. The rad cap doesn't seem to fit the brand new Valeo rad that was installed a few months ago that well, so I wonder if that isn't the issue.

Thanks for the help guys, I feel kinda silly for asking now, but gotta get used to driving something with the engine in the front again!

 

It's an awesome little car. The tranny is an extremely low mile Fiero 5 speed. It's held up fine so far, and according to the folks at the car show I left last summer, its enough to lift the front wheels.

 

I had a full service on my ram and the faucet finally turned off too....lol.
