3800

Hi guys, I'm completely new to this forum and a new car owner. I admittedly don't know anything about cars but I just received a 2003 Park Avenue Ultra with 55K Miles and it's running great so far. However, I have read and heard that as great as the engine is, there are things that need to be...

Good Evening Everyone, First post and new member, I own a 2003 Lesabre Custom with 133K miles on it. Been garage kept for the past 4 years until i got it back running last year. Replaced The fuel pump, upper and lower intake gaskets, coolant elbows back in 2021. It sat for a bit then...

Howdy folks, I'm part-way through an engine swap putting a Series I 3800SC into an '88 Fiero, and to make a long story short, I have the ECU and the engine harness from a '95 Riviera, but not the section of wiring harness that goes between the firewall and the ECU. I've been scanning the local...

Hello, I have recently replaced the coolant elbows going through the idler assembly acouple days ago. I have removed all air (or so i think) out of the system. My issue is that I have very little to no heat comming from the vents when the temp is set to max and the engine is at operating...

Hey guys! Thank you for taking a minute to try and help me out! :) My girlfriend and I have recently purchased a 2008 Buick Lucerne CXL with the 3.8L 3800 Series III motor. We got gas yesterday after work, and parked the car in our driveway like 2 miles away. Car ran fine the entire drive...

so i bought this knowing it probably needed a lim gasket at the very least. this was about 2 years ago. over that time i found the coolant elbow had broken off inside LIM. so i replaced that and the lower and upper gasket for good measure. after putting all back together alternator wouldnt...

Hello everyone, I drive a 1993 Buick Park Ave Ultra. So I discovered an odd sound coming from what seems to be my coil packs... now, I DO have a manifold leak as of now, and need to fix it soon; however, this new sound I haven't heard before. When the engine is running, I'm hearing a faint...

Hello all, I just bought another one of these because I had one before and loved it. IMO, one of the nicest driving cars you can buy, having a great mix of quiet, smoother ride, awesome power, and responsive handling. That at being said, they do have some quirks. Both of mine have had one of...

I'm starting to pull my hair out... After putting half a tank of gas in at a gas station, my check engine light would come on and off. My Lesabre stalled out on me 5 times over the next 3 days while around idle in gear. I put in octane booster for the remainder of the bad tank and put a can of...

Ok so here's the deal, about 6 months ago, my transmission started shifting very hard when it got warm. So I figured it was a transmission problem. Then 2 months ago I changed my oil and drove the car the next day and it shifted hard like usual when it got warm. The day after that, it stopped...

Recent car purchase, and I am relatively unfamiliar with front wheel drive nuances that may be found with the 3800. There is a "come and go" medium pitched whirring type of sound coming from the engine compartment that can be heard through the firewall at idle and higher RPM's in neutral. This...
