Tip & How-To about 2007 Chevrolet Impala LS Sedan New Cars

All cars and trucks Preping for installing long block Engine

This is a Guide for installing A long block engine in your car, this procedure is for all engines 4 6 and V 8 engines, this is to help you to determine if the engine that you buy is good enough to install in your car. Many engines I have bought that have been crate engines have had problems with bad valves or oil pump and these tests and procedures will help you to install a engine with the least amount of trouble as well these tests will keep you from installing a bad engine and having to remove it and replace it with a new one. Most engine re-builders don't pay for removing and replacing the engine unless you are a professional shop. This guide will include you should check and replace while the engine is out of the car. The things you will check is motor mounts 02 sensors oil lines power steering pump steering rack and pinion and rubber grommet that connects the steering to the gear box. As well I will suggest that you replace the following switches and components before installing the engine so that you don't have to do so after you have the engine in place. This is called preventive maintenance and will assure you will have a engine that will last uo for a long time to come with the least minimum problems over the life of the rebuilt engine. Some of the things you want to check before installing the engine is rubber components such as belts hoses, power steering hoses and vacuum lines, if they are brittle replace them, also replace heater hoses and heater shut off valve before replacing the engine back into the car.

Be sure to check rear mail seal ad if you have a automatic transmission make sure the front pump seal is in good condition, if you are going to change it ow is the time. Also if you have a front wheel drive now is the time to check the drive shafts for being loose if they are replace them now, if the boots are torn on the half shafts then remove and replace now.

Replace 02 sensors at this time, 02 sensors wear out with time and become lazy 02 sensors which mean they don't adjust the fuel trim fast enough, changing them now will pay for gas in a years driving alone so replace them if you can afford to do so.

HAVE THE RADIATOR Rodded and cleaned and hot tanked to get rid of plugs and dead bugs in the radiator. Have the radiator r pressure tested and replace the radiator cap with a new one, there is nothing like losing a brand new engine for over a 5 dollar radiator cap.
F the long block does not come with a water pump please replace with a new one now, water pumps wear out over time and again you do not want to lose an engine for a $40.00 water pump.

Here are a list of parts you should check and replace as needed on computerized engines. 1. Load sensors, Map sensors, VAC sensors Baro sensor, Throttle position sensor, Stepper motor, Mixture control solenoid, check for updated e prom on GM cars, Catalytic converter, EGO valve, sensor and egr valve. Check air flow sensors. Coolant temperature sensor replace. Crank shaft sensor Rpm sensor cam sensor. Electronic spark control on distributor type engines and coil packs for non distributor engines. Idle speed control, ac Sensor low and high pressure switch, Knock sensor, hall effect switch if equipped. Turbo boost gate if equipped with turbo, Torque converter clutch switch, road speed sensors and sending units for heat oil.

On the engine You will want to put compressed air into each cylinder to be sure all valves seat and hold air pressure.

Next be sure you pressurize the oil system with a oil pig or pot and put at least 3 quarts of non detergent oil in the block then pressurize the oil galley from a ¼ inch pipe plug, apply oil to the block let the air escape out of the holes then turn the engine ¼ turn and continue to allow air to work out of the engine. Once oil is primed use a drill to run oil pump and see if it holds 40 psi of oil pressure. If it does then your ready to install the engine. Just before if you have a clutch then replace the clutch throw out bearing and have the flywheel surfaced at this time better to do it now than have to do it in two weeks.
Before installing the engine be sure the exhaust bolts are loose and replace exhaust donuts if needed at this time. Install the engine and hook up all hoses wires and motor mounts flywheel bolts fuel lines and throttle plate cable install new motor mounts and engine mount bolts. Tork bolts to specifications tighten flywheel bolts and check all components to be sure everything is hooked up. If you have an automatic replace the rubber hoses and clamps going to the oil cooler on the radiator. Fill Up radiator with water and burp system so that there are no bubbles. Be sure the spark is disabled and crank the engine over for 30 seconds, does the oil Gage go up? And is there any weird noises? In there is oil pressure and no weird noises then hook up coil pack then start the engine run for thirty seconds and check engine oil and fill to full fill radiator to full mark and do the same for automatic transmission.
