Where is the engine temperature sending unit on a 2005 Chevy aveo?

Answer 1

Passenger side of vehicle rear side of cylinder head. I have a 04 I just replaced the coolant sensor (they call it that) I purchased at Auto Zone for $23.80. The reason I replaced it is because whenever I would start the vehicle the motor would rev to about 3K RPMs. Whenever the vehicle was turned off and then restarted the sending unit would indicate zero degrees indicating to the ECM the vehicles engine was cold causing a cold start fuel air setup. I replaced the timing belt at 58K miles because I received a letter from GM Protection letter stating if the timing belt broke before 60K miles GM would pay for all the repairs including any parts caused by the timing belts failure. After 60K miles the repairs would be entirely on the consumer or owner. SOO I called local Chevrolet dealership speaking to a service writer. I asked what components was recommended replaced when the timing belt was replaced?

His answer was "just the timing belt". The valve cover gasket could be reused also unless it was damaged while removing the 0valve cover. So I had a local garage replace the the timing belt and change the oil and filter while they were there.

So 4.400 miles later while driving near my home at 30MPH the engine died while in motion. I attempted to restart the engine but it failure restart it would turn over but ignite. I had the vehicle towed back to the local garage who discovered the timing belt did NOT break but the timing belt tensioner broke this time only 4,400 miles after I replaced the timing belt. Six(6) valves was belt are damaged. Each valve cost like $30 bucks(it has a total of 16 valves). You must purchase a head gasket ($44.00 I think) you must take this cylinder head to a machine shop who charge about $300 bucks to pressure check each valve to make the valves are seated and holding pressure(exhaust or intake valves). To remove the valves that do hold pressure(bent valves) caused by the timing belt breaking. The machine shop must cut the cylinder head on a machine which grinds the head level so it will not leak cylinder pressure when installed back to the top of the engine.

The local garage who replaced the timing belt also was advised by Chevrolet that when replacing the timing belt only the timing belt needed to be replaced so they would not warranty any work regarding the timing belt belt they replaced because the timing belt did not break this time it was the tensioner which broke.

Long story short this NO GOOD CAR DAWOO PIECE OF FECES CHEVROLET SNUCK IN ON THE AMERICAN PEOPLE SHOULD BE CRAMMED RIGHT UP THE RECTUM OF THE CEO ARE WHOEVER AT CHEVROLET WHO BOUGHT THIS PIECE OF FECES FROM THOSE FORIEN AHOLES. This car was purchased by wife but has caused me a lot of GRIEF AND MONEY!!!!!!!. THANKS, TIM.
