Boy, do I feel stupid! Okay, I'm no mechanic so . . .

Okay, I finally got around to installing my 180° thermostat. I undid the two bolts from the T-stat housing from underneath the car, let about two gallons of coolant fall into a bucket, and replaced the stat and gasket in the same orientation. The gasket goes "under" the stat, right (closest to the ground)? Anyway, I tightened the bolts and everything seemed snug and fit.

Then I unscrew the bleed valve on the top of the coolant hoses and fill it with one gallon of coolant. I start the engine, run the car a minute with the bleed valve open, then add about one gallon of water. As I continue to fill the bleed valve, just before I'm about to finish pouring the gallon of water, the reservoir starts to overflow--I stop.

I screw the bleed cap back on and pull out of the garage to go to the store about a mile away to buy a turkey baster to remove the excess fluid from the reservoir. After 200 yards, I notice the water temp gauge start to climb--it climbs to about half way to the "20 MPH" mark in about 30 seconds. I immediately return to my garage, park and kill the engine. I then attempt to repeat the fill-the-bleed-valve trick, but it only takes about a cup of water this time.

I start the car and I hear a LOUD . . . "SQUEAAARRRK . . . SQUEAAARRRK" sound. Thinking I've seized my motor, I shut the ignition. But I look at the temp guage and it now only reads about one-third of the way to the "20MPH" mark. So I open the hood and start squeezing the big black hose to the right of the bleed valve to force any remaining air bubbles out of the system. A few dozen small bubbles do come up through the bleed valve--I do this for about a minute until I see no more air bubbles. The reservoir is still pretty full.

Thinking my engine is gone anyway, I start the car again . . . "SQUEAAARRRK . . . SQUEAAARRRK" but this time I rev the engine a bit . . . a single "SQUEAAARRRK" of the same tone. A bit relieved, I notice that the "squeaark" noise doesn't seem to correlate to engine RPM. I removed the reservoir cap and the bleed valve but still got the noise.

Is the gasket not seated properly in the T-stat housing making this "trumpet" sound? My engine's okay, right (water temp gauge never made it past half way to 20 MPH) ??? Help!

2 things, 1. the thermostat may be backwards, 2. may just be fluid on the belts.

Thanks, merc406! Pretty sure the stat isn't backwards. The spring thingy is pointing "up" (toward the sky). I was WONDERING if it was just the fluid on the belts . . . Any other comments? Anyone?

It's been a while since I've done any work on my cars, but isn't the spring part of the stat supposed to point into the block?

I dunno, but I'm pretty darn sure I installed it the same way . . . when I took the old one out, the spring part was facing toward the sky.

Before you do anything else, rinse off the pulley's and see if after starting and running alittle that that clear's up the problems.

Neat sound eh? That sound is coming from your waterpump, it's got air going through it. If you've bled the system properly this typically doesn't happen, but the one time it happened to me, after blipping the throttle and just letting it run for a few minutes, it disipated...

WHEW!!!!!!!!!!!!! THANKS LOGAN! Yeah, that was a "neat sound." Like ducks having sex? . . . Through a MEGAPHONE! It was THE scariest sound I've EVER heard from a car!!! MM.net comes through again!!! Thanks for everyone's help! Well it went away after I let the car alone for a couple hours. I just got back from my test drive--car warmed up normally to operating temperature after about 8 minutes. Drove for 20 minutes total . . . water temp needle stayed JUST shy of the "20 MPH" mark! YAHOO!!!!!!!!!!!!!!!

By the way by "blipping the throttle" you just meant tapping the accelerator?

The Marauder stat has an unusual mounting location....not the norm. Well, normal on a Fiat....:D


Glad it's all good man, I read that post first thing this morning but wasn't gonna say anything I wasn't sure of. I figured waterpump though, they make some interesting sounds under the right conditions!

Yep, that's about as close a description as any... Ducks through a megaphone. :)

Canuckism I imagine there... Tapping the accelerator... :)
