Question about 2004 Chevrolet Aveo

2 Answers

Can I use 2006 or 2007 1.6L engine in 2004 Aveo??

I want to replace my 2004 Aveo engine, and was hoping to be able to put in a newer 2006 or 2007 engine. The cross reference info says 2004 & 2005 only, but I know the size & type designations are the same for 2006 & 2007, even though they are not listed as "interchangeable". Does anyone know the difference in these two generations of Aveo engines?
If the block & head are the same, I can bolt on all my old stuff to the new engine. But I don't want to find out that the transmission does not mate up, or the manifolds, starter, etc.
Anyone know the real deal on these engine differences?

    Thanks Guys, but the dealer doesn't know squat about the variation details from year to year (I already went down that road). Only that they are not the same & so "I should not use them". They only see the part & model numbers, & if they are different they can't tell what the differences are. The parts guy was appologetic, saying that "mother GM" can't or won't give them that info, even when they request it.

    And this one is not a 4 year cycle, at least part number wise. That's why I need to know the detail from someone who is intimately familiar with these engines (Daewoo engine used in Daewoos, Suzukis, and Chevys). The "engine" did change for 2006/2007 vs. 2004/2005, but I don't know if the changes effected the block/head, or just smaller things like harness, fuel system, ECM, etc. I'm hoping the basic block/head are the same so I can scavenge all my old stuff & mount it on the newer block/head. Keep the answers coming . . . thanks. Dnick

You should be able to interchange them....its every 4 years that they change the design of an engine and i believe yours can be changed since they are within 3 to 4 years cant always go by the book so you have to look both engines over closely and see that everything looks the same top and bottom and if they are go for it.

There are Variations in these years. Call the Lacal Dealership and Ask for the Parts Department to see Exactly what the Differences are on these.

    The Blocks should all be Basically the Same. The Wiring Harnessess will be the only Problem that you could have.

Does an 04 aveo have an interfernce engine?

Yes a 2004 chevy aveo with a 1.6 L inline 4 cylinder is an interference engine. Hopefully you did'nt snap the timing belt while driving, because usually it will bend up some valves and even could crack a piston. Most likely if that did happen you will need to take the head off and have the valves inspected / replaced and inspect for piston damage as well......Mike

Engine will die

There is a Communication problem between the Transmission Control Module (TCM) and the Engine control module. That is the bad news and is why it's shutting down the engine. 
The good news is i believe there is a TSB recall on the 2004 - 2007 chevy aveo for the P0700 problem so it should be covered under warranty. 
Believe the TSB# 05-06-01-030D
Good luck and hope this helps and hope it's not a bad ECM. Check the wire harness to the ECM and TCM, look for broken wire or the harness it self gone apart.

Hello Joe...The Aveo has had it shares of problems, and this is one of them....NHTSA issued several bulletins on the 04 Aveo...this following is the one pertaining to the shift interlock.....

Make : CHEVROLET Model : AVEO Year : 2004
Service Bulletin Num : 070730007 Date of Bulletin: APR 01, 2007
NHTSA Item Number: 10022265

Take that bulletin number to your dealer and see if they can help.

Untill you can get it repaired heres a little tip for getting it out of park....There is a a little hole in front of their gearshift lever that can correct the problem, temporarily. It should say "brake interlock release" or something like that. With car running, put a key-size object into it and push down while moving the lever. It does not damage the transmission, it just releases the lock. (make sure your foot is on the brake)

Now for the brake light you have power at the switch you replaced? If so go to the relay and check there...if no power there it's probably a bad ground. may or may not know, but the timing belts on these Aveos are prone to failure at aprox 50k ...these failures have caused severe engine damage.
Good luck...i hope the information i've provided you find useful.
Please time to rate me.

2004 aveo timing belt broke, all valves bent

just go to any junk yard and find a used deawoo lanos and pull the head if timing belt was not broke, if it looks good, its a exact fit 100%, no special tools needed, just normal wrench set and torqe wrench. after head is installed, get a gates timing belt only.
