Default How reliable is the 3.1 engine

Someone near me is selling a 2003 v6 Malibu with 93k miles for 2500$. Sounds like a steal. Car looks clean but I have read the 3.1 engines give people a lot of trouble, like blown head gaskets, ext. Give me your opinions on weather or not I should buy it.

My old Pontiac GP has the 3.1 V6 and my son now uses it every day. Last I heard, it had >140,000 miles. We did have one engine repair at around 60,000 miles, can't recall what it was exactly but it wasn't a head gasket.

Of course, all this is under the theory that the Chevy and Pontiac engines are the same.

Vegabond - they are, but there's more than 1 3.1 V6.

MarkAnthony404 - I dunno how durable they are, I've only got 300Kmiles on mine so far. It HAS eaten two sets of lower intake manifold gaskets (which is the main problem, I think - going from the motors my nephew used to get in his wrecking yard. And from anecdotal information here.)

Ask me in, oh, another 700Kmiles

In other news, the front main bearing seal has started leaking oil - so I'll probably be learning how to swap that out in a few months Overall, though, I'm VERY pleased with the motor, durability, and performance of the 2000 Malibu.

wow thats a lot of miles. I just need a car to get me through school for the next 2 years. Sounds like that car is a safe bet.

Now that I think about it, that seems to be the issue we had. Thanks, Ralph!

The main issue with these motors is the intake manifold gaskets. The Dexcool coolant they used ate threw them. I do believe they fixed the problem, I can't be sure though. I have 194k on mine and have had it for a year next month and had no problems with mine. Besides the power steering pump pulley. I just don't use Dexcool in mine. In my opinion very reliable and I love my Malibu.

My uncle drives a 2003 a little over 100 miles a day on his round trip to work. He's got around 250k on it right now. I know he's done a few things to it, but I don't believe there was anything drastic. If I remember right, the last thing he mentioned was replacing the water pump.

I've had the same problem..Twice also. Other than that and the wather pump going once I have had no problems out of my 2000 3.1. I'm @ 140k and still running strong. It has only failed to start twice in the almost 7 years I've been driving it daily...once when the starter went bad, and once when the fuel pump died. Can't fault the motor for that tho.

Well, if we're going to count fuel pumps ...

Default Re: How reliable is the 3.1 engine

I'd have to say the 3.1 is a pretty reliable engine. I've got a 2000 malibu with over 315,000 miles. Currently she's sitting at 317k and change. So far I've had to replace the intake gasket once, fuel pump once, an oil pressure switch, and currently working on replacing the starter for the second time. All things considered that's pretty darn good, I think. Especially for an engine made by the same company that produced possibly the most unreliable engine ever made ( the infamous 2.3 liter quad 4 )
