Simple answers from Kacal's Auto & Truck Service for houston timing belt replacement

Question: My friend had a broken timing belt and it was very expensive to repair his engine. What can I do to avoid a broken timing belt?Kacal's Auto & Truck Service Answer: Well, a broken timing belt can lead to one of the most expensive engine repairs Houston drivers will ever face. The good news is that replacing your timing belt on its recommended schedule can help avoid those problems. Here's a brief overview of what the timing belt does: Air is drawn into the cylinder of the engine through the intake valves. After the air and fuel mixture is burned, it's pushed out through the exhaust valves. The timing belt, which is driven by the engine, turns the camshafts which control when the intake and exhaust valves open and close. It is important that the opening and closing of the valves take place at exactly the right time for the engine to run properly. Beyond that, on some vehicle engines, the valv ... read more

Fuel Injector Cleaning In Bellaire

In very simple terms, a fuel injector is a valve that squirts fuel into your vehicle engine. Your engine control computer tells the fuel injector how much fuel to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. High temperatures under your hood and variations in Bellaire gas quality cause fuel injectors to be fouled with wax, dirt, water, additives and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. When your vehicle's injectors are dirty, the fuel doesn't burn as efficiently, resulting in poor fuel economy and loss of power. So it's important to keep your fuel injectors clean. We can perform a full fuel system servic ... read more

Vehicle:    2005 Lexus GX470 Base 4.7L, V8, MFI, DOHC, Eng Desg 2UZFE Mileage:    116,853 Customer Concern:    The left rear suspension is lower than the rest of the vehicle and there is a code 51. Replaced the left rear air suspension bag but it will not fill up. Tests: 1. Code 51 indicates that the air suspension pump ran for more than 100 seconds but the vehicle height did not change. Determine if the pump is working properly and that it is able to build pressure.  2. Test the rear height control valve and determine if it has battery voltage applied to the Purple/White wire and good ground on the White/Black wire. If so, the control unit is trying to open the valve and direct air to the left rear air suspension bag. If the height control valve has power and ground for the left rear circuit and there is no air coming out to the left rear air suspension bag, the rear ... read more

Tests: 1. Check the resistance of the Variable Charge Motion Actuator (VCMA) motor from terminal 4 to terminal 5. The specification is 3.4 to 4.4Ω at 68 degrees fahrenheit. 2. With the key on, actuate the VCMA motor with a compatible scan tool and confirm the change of VCMA feedback sensor signal and the sound of operation. The specification is about 0.84 volts open and about 4.16 volts closed. 3. If your scan tool will not operate the VCMA motor, backprobe and monitor the VCMA position sensor signal at terminal 2 Black/Orange wire with the key on and apply battery voltage to the motor at terminal 5 Orange wire. Pulse a ground at terminal 4 Pink wire and the position sensor signal voltage should chan ... read more

Vehicle:2005 Lincoln Town Car Executive 4.6L, V8, MFI, SOHC, VIN W, GAS Mileage:117,000 Customer Concern:The Right Front (RF) cornering lamp is on all the time whether the ignition is on or not, unless the parking lights are turned on. Tests: 1. Disconnect the multifunction switch and look for the light to stay on or turn off. 2. If the light goes out with disconnection of the multifunction switch, it would support a shorted multifunction switch. 3. If the light is still on with the multifunction switch disconnected, disconnect the RF cornering light bulb and check for the presence of voltage to the bulb on the Brown/White (BR/WH) wire verifying it is shorted to a hot-at-all-times circuit of the harness running between the RF bulb and the multifunction switch connection. Inspect the harness and address the short, or cut the circuit as the RF cornering light bulb and the multifunction switch and run a rep ... read more

Vehicle: 2003 Chevrolet Express 1500 Base 5.3L, V8, MFI, OHV, VIN T, GAS Mileage: 128,179 Customer Concern: No start, no fuel pressure. Replaced the fuel pump and relay, still no fuel pressure. Tests: 1. Remove the fuel pump relay and check for power at one terminal from fuse 12 (20 amp). 2. One terminal should get 12 volt power when the key is turned on for about 2 seconds and also when the engine is cranking. This is from the Powertrain Control Module (PCM) pin 9 of the Green connector, a Dark Green/White wire. 3. One terminal should be a good ground to G102 and the other terminal should have continuity to the pump. Putting 12 volts on the pump terminal should show 12 volts at the pump with the pump plugged in. If the voltage is low at the pump there is a wire problem between the relay and pump, inspect the connections under the under hood fuse block. 4. Verify the pump ground is good and the ... read more
