#LT1 SCANMASTER HOW TO#

Has the car been switched over to the green coolant, or are you still running dex-cool? If the system wasn't properly flushed during the switch, the silicate and non silicate coolant will bond together in your radiator and cause all kinds of problems. Perhaps you have a leak in your cooling system? I'm not very familiar with LT1's, but my last thirdgen had a bad intake manifold gasket and the small amount of air that was sucked in through it would occasionally cause my coolant to boil. And I don't understand because it has a new thermostat and water pump. Runs at normal temperature on the move but if I sit, I have to click on the defroster or it gets up to the third line on gauge and higher. The reason I am lost is because the cooling system runs fine. One thing you want to do before tweaking anything is to learn all the acronyms and parameters of your engine/computer so you know that 'this setting controls that function' etc.

Your fans should turn on around 226* for the low speed and 235* for the high speed.ДЄlso, your fans will turn on if you turn on the a/c, defroster, etc.ДЄs well as turning on if you have an SES light.ДЄnd seeing as how you arent overheating, your fans seem to be working properly and turning on when your egr code trips.ДЄs for tuning, there's a bunch of places online that have step by step basics as well as classes that you can attend to learn how to tune a car properly.

The EGR code is probably just the EGR valve itself either being dirty or just plain worn out.

And if anyone knows of a tuning tutorial for dummys, I would be interested in reading up on it. I am looking for the correct bin and xdf files. Since I have the ALDL cable, I am now interested in learning to tune the car myself. I believe it has been since I bought the car, but I passed inspection and they probed my tailpipe.ДЄm I correct by saying the fans not turning on and the EGR should not be related?ДЄlso, what are the most common causes for code 32? The only time they will click on is when the SES light is on for code 32 or I can always click on the defroster.ДЄlso, I just found out today that my CAT is shot. The funny thing is, ever since I bought the car, it seems the fans don't turn on. I finally ordered an ALDL cable and scanned it from the laptop and it pulls a 32 - EGR system fault. I have never noticed any power loss and my average MPG is about 17-18 city and around 22 highway. I wasn't able to check it before I did the head gasket because of the whole OBD 1.5 mess.

Problem is, since I have had the car, I have had it throw a code. I have also replaced the water pump since I have owned it. Just had to do a head gasket, got heads remanned and new seals and gaskets all the way around. Bought a 1995 Z28 A4 September last year.
