Had new battery installed on a 2002 PT Cruiser. Later the same day the car was
cutting off/stalling at red lights. A diagnostic came back with a computer failure.
Had a new computer installed/programmed....
let your mech do his job.?
and if the battery drops below about 10v, the ecu will fail (lie), and guess what, that is NOT a bad ECU./pcm/bcm,tcm, etc.)_
if you do\'t like your mech. get a real ASE mech. and win.
real ASE mechs never throw parts, ever. (cept a tune up)
learn to monitor cars 12vdc system, get a harbor fright , charge testing tool, cheap, has LEDS. or learn to use a voltmeter
my car has a dash gauge, called volts.
if the volts shows at 14v running then the charge system is working
and the ECU is now working good, with full voltage.
engine off, the voltage is 12.6v (room temp) and means battery (rested) is fully charged. STATE OF CHARGE, method.
over heating must be fixed first.
it can wreck and engine fast. stop dont pass go, do not collect $200 , halt./
why not put a new fan belt on it for $10.
get a GATES or GY, Gatorback
now lets delve in to why you mech is (asleep in class?)
belt new, and tensioned to spec. some belts slip and do so with out a sound!, gee, get a new one? why risk $3000 motor for $10 belt. ?????
park a hot car, look at every inch of engine bay and pavement, for green AF leaks, (fix that first) got low water level in rad, every morning cold?
fix that first, and is #1 DIY check anyone can do.
Look in the rad neck cold, not the overfill tank, that be weak.
now what they do:
1: compression test. (do that first any time and engine overheats
takes 30min or less if sparks are easy to reach. some are not.
2: rad leak down test. (cracked block or head) a hand pump tool.
3: exh, fumes in rad neck test. blow head gasket. a tool.
Blue green liquid changes color, oops? you found it.
4: checks temperature of each rad tube, for same temp drop
end to end, if this passes the RAD is good. All pro mechs know this test and use an IR pyro temp gun, ,and saves many a burned hand. and finds bad rads, so easy its like MAGIC !
if all else fails. (passes above)
we then remove the pump, some pumps can be very hard.
FWD cars sux this why, (buy a jeep!)
the impeller gone or rusted to nill.
bearings shot and leaking green. out the front.
seal shot in same , bad bearings always wreck that seal,.
humpty was pushed.
Im sure i missed a step.
but you get the idea.
and if your mechanic do these. find another.
A: he checks cam and spark timing if way off, the chain or cam belt slipped. belts last 60k, period.
B: The ECU many have ERROR to report,
in fact any scan tool an monitor engine heat.
and all these facts are considered
Over heating (macro) can be
engine producing too much heat (retarded timing?)
or bad cooling system.
or both. (straw breaks camels back deal)\'
Keep in mind Entropy wins everytime.
and find a ASE mech. and win big.
btw 2, a pro mech replaces the ECU last, never first.
as you can see, he failed you. here.
i bet you where taken for a ride....
