Default 2000 Camry - smoke coming out

Hi,

I had smoke coming out from the radiator today. When I checked, the
hose connecting the radiator to the engine had come off. I connected it
back and started the engine. But, the hose got very hot. I took it to a
mechanic, but he said that I need to change water pump and timing belt
since it is nearning 60000 miles. I told him that the problem could be
the thermostat and not the timing belt. I finally convinced him to
change the thermostat and check. He changed the thermostat and added
new coolant, but that did not solve the problem. But, we found that the
fans did not rotate. So, he now says that the problem is the 2 fan
motors and wants to change them. If that does not solve the problem, he
wants to change the water pump and timing belt. Is he ripping me off?
Has anyone encountered a similar problem?

Thanks
V

well the fans should turn on at about 198* F just run the engine for a
little while and see if they turn on, or you can turn you a/c on.
when the a/c is on the fans should turn on as well

It could be a fan but unlikely 2. You put the hose on and drove it, did
you have coolant in it, you might have caused alot of damage and wont
know for awhile. I think you have many issues to look into.

If the fan is not the problem, then what could be causing the engine
overheating. Is changing the water pump and timing belt the only option?

Timing belt would only be because it's worth doing while they do the labour
to get at the water pump, not for overheating. Sounds like the mechanic is
clutching at straws if he doesn't know whether it's the fan or water pump
or... Did it overheat first time because the hose fell off of did it fall
off because it got hot? If the head distorted from that episode, it might
now be letting (very) hot gas into the water causing overheating. If it's
losing coolant that's a sign, or grey oil under the filler cap, or a
pressure test at the garage. If fans don't run it is quite likely the temp.
switch. Mechanic sounds suss.

Get your fans working first, you "mechanic" did check-test them to see
they don`t work, right?

I made him check the fuse for the fans and now he says that the fuse
was the problem and the fans are fine. But the car is still
overheating. So, he is saying that the water pump has the problem
although there is nothing to prove it. How can I make sure that the
water pump is what is causing the overheating?

Thanks

My uneducated thought is a water pump is working or not working, no
imbetween. If thermostat is new, I would consider a radiator that is
crudded up, colapsed or blocked hose. Did this just start or is it
ongoing. look inside the radiator buildup will show on the fins. If it
has not been chemicaly flushed , is dirty and hoses old I would try that
first. If it is aftermarket thermostat New does not mean good, I have
had bad luck with several aftermarket thermostats, take it out and try
it. Did air get bled out, did you check coolant level often when cold.

With all due respect to your mechanic,..find another one. If your car is
overheating, the faults maybe one or more of these,

-lack of coolant
-pin-holed hoses or old hoses leaking at clips (lose coolant)
- failed pump seal (lose coolant)
-leaking welch plugs in block (lose coolant)
-lack of coolant cooling due radiator clogged after extended use of ordinary
tap water.
-leaking radiator, cracked or holed(lose coolant)
- lack of coolant cooling due fans inoperative
-"blown" headgasket causing coolant loss
-cracked or warped head (lose coolant)



...one of which occurs after the initial overheat and serves to keep the car
losing coolant until its fixed:- ie cracked and or warped head.

The unfortunate thing is , that once an engine has been even moderately
overheated, if it has an alloy or aluminium head, it may need major work and
if not done will continue to cause overheating.
