New Prizm Noise by cpan13
Jan 04, 2001 (5:43 pm)
Reply
I purchased a new 00 Prim in August. Initially had funny, rhythmic "wuh wuh wuh" noise from engine at around 1200rpm/idling. Dealer said it was "normal" noise. Now at 7000miles, cannot hear it inside the cabin, but has rhythmic "pfh pfh pfh" noise when listening to engine outside.
Is this a "normal" noise other Prim's have? Anyone else have this noise?
 
My A/I light is also ALWAYS on when you are on Window Defrost mode - should it be?
 
When I first start my car, it idles at 1400-1600rpm for 2 minutes before dropping down to 900-1100. Is that normal? (Oh, I live in Michigan where it's been 0 degrees)

Can't tell you about your Prizm's engine noise. I have a 99 Corolla LE. And I live in Ann Arbor. So not too far from ya.
 
I can't recall hearing any rhythmic noises. Engine is louder when it's cold, but once it has warmed up, you can not hear it inside the car until about 40 mph.
 
As for the idle speed. 1400-1600 rpm is normal. It's programed to idle at higher speed until the engine warms up. Because a cold engine produce is when it's least efficient, that's why it's programed to idle higher to warm up faster. It's listed in the Toyota's owner's manual, don't know about Chevy's. Once it's warmed up (you can watch the engine temperature gauge), the idle speed should drop to just below 1000 rpm.

For what it's worth i'd recommend the prizm to anyone.I bought it over it's twin the Corolla because i saved about $1000.(bought it new in'96 for$12,000. a/c 5speed am/fm rear defog....can get the same car for the same or less today because everyone still wants suv's)Now with 60,000 miles i have done nothing but preventive maintenance(oil every 3k,new tires,tune up,one tie rod end).You will lose a little on resale(if you are like me resale value means little when you keep them for 8-10years) but in general you will pay less to begin with.Great little car!!

i was looking through my g-friends owners book at her replacement intervals for her 95 cavalier i have a 95 prizm both caomrable size and class of cars, hers does not reqire half the stuff mine does, especially the timing belt but also no valve clreance adjustment,rotor,cap,wires,drive belts,i thought toyota engines were more technically advanced her cavalier is as old as mine w/pretty same almost 90k, my boken timing belts could cost up to 2,000 to repair,sounds like gm makes a more thoughfull 4cyl engine design,a belt that can ruin the engine if it breaks,
come on toyota (geo,whatever this car is)gm,toyota,or geo

You trade maintenance costs for liveability and for reliability and durability. The Prizm is a much more refined, easy-to-live-with car than is the Cavalier. It will, with proper maintenance, far outlast the average Cavalier - 100,000 mile maintenance intervals may sound great, but in many cases, a Cavalier won't make it that far, nor is that type of service interval realistic.
 
I'll venture to say that in 100,000 miles of driving, the repairs to a Cavalier will end up costing more than the maintenance on a Prizm.

Belts tend to be quieter, for one, and allow a more compact engine. No, a broken timing belt on a Toyota 1.6 or 1.8L engine will not damage the engine (as it will on a Honda, or Neon, or other car with an interference-design engine).
