Hi everyone, I own a 1994 buick regal custom with an L27. I hope to be a long time member. Im 16, so my enthusiastic car modification days have just begun.

Im not sure where to post, but I just bought a 180 degree thermostat and I dont know how to install. I searched through the forums but didnt see any pictures. Does anyone have any? Thanks!

Follow the upper radiator hose to the engine and it'* in there. Unscrew the housing, scrape off the old gasket, remove the old 195, put in the 180 with a new O-ring, put on a new gasket, and screw it back together. You may wanna drain some coolant first.

Welcome to the club.

Is it that hose at the bottom of the picture, that goes down to the intake manifold, and turns into metal? With a little bolt or something sticking out?

The bolt on top is a bleeder valve for the air. You might want to drain some coolant first (quart or so) before taking out the t-stat otherwise you will lose it over the engine. There should just be two bolts holding the t-stat housing to the block.

Ok got it!! Now, whats my best bet for exhaust? I want a deep mellow tone, that i can hear fairly loud, but I like smooth, not raspy.

I think the flow master 80 series is what alot of people are running..

Hey nice engine!!!



Oh yeah it'* prob cleaner then that, save some stuff that'* loosely on there now from driving. L27 owners unite!!

Check my sig, add it to yours if you like....

Welcome, regal, glad to have your here. Just don't forget the fiber gasket for the 'neck', and the rubber o-ring for the stat. You don't HAVE to drain coolant first, but if you don't, be ready to top it off afterwards. And do this on a cool engine

Thanks all! Thanks for the opinion on the 80 series flow, butit sounds a little too high pitched and raspy for me. I want more of a low note sound through most of the range. Any ideas?

Magnaflow! Many members here run that as well, and there is the ontario sound-off you can get from someone.
