calcium66: I have just replaced the engine for my Alero 2002. An engine from a 2001 Impala was in stalled in the Alero. The Mechanic at first states that the PSI for the fuel pump is 38 it should be 55-58. We changed the fuel pump and fuel filter- and it gave the same reading. The car would start twice a day like 9 hr apart. If I start the car now and shut it off it will not start-will crank but wont turn over. I changed cramshaft and crankposition sensor - still the same thing. The only thing that works is disconnecting the positive charge on the battery for 30 secs with the key in the on position. I also cut the security wire (thin yellow wire} while the car was running it still will not start again after the first start. Any solution?

Bud E: Do you know for a 02 Rendezvous, can the engine come out from the top? I read somewhere it needs to drop out from the bottom.

j loft: hey the guy with the brake light problem ,if it not the bulb mine was the turn signal switch most g m car run both the brake light and turn signals thru it, easy to tell if you have only one bulb 

Ricky Temples: Most shops don't want to work on my car, especially doing my new exhaust, they all want to claim that it's $2000 to do, and they bullcrap me everytime. I just need someone in Georgia to remove both manifolds and either replace them with oem product or pacesetter headers. 

Davie Jones: The only reason head gaskets go bad are either too much pressure in the head by over turbo charge or a blower or someone let a antifreeze leak prove fatal when they instead of replacing it with the good stuff put in good antifreeze coolant and regular tap water! Tap water has calcium and rust and all kinds of bad stuff in it and what happens is that the calcium collects around the shaft of the thermostat during the summer and when the first hit of cold weather come's around it seizes up and won't open when the engine get's hot and over pressurizes the coolant ports and it finds the weak area which is the head gasket and it blows a hole between the cylinder and the coolant ports which don't ruin the engine but makes you have a job changing the head gasket. That is if it don't crack the block! The only way to find that out is changing the head gasket and doing a pressure test on each cylinder! Tap water is not our friend! Use distilled water only in your radiators! And never trust premixed coolant ever! I never use it! You can't trust companies to be honest about using distilled water in their premixed antifreeze! 

3waymore: Please tell me two things. 1) how did you get the lower engine to tranny bolt out on the firewall side? 2) how did you get to the exhaust bolts. PLEASE help soon

Byron Da Shirtmaker: How much do u charge to swap out a engine? 

Miguel Barriga: 3.1 and 3.4 are rare here in Coachella valley u just see Honda's and Toyota's
