1995 Passport - Overheating after Timing belt tensioner change -- belts removal/installation

Only a slipping belt connected to the water pump can make a car overheat.

Alternater belt slippage would cause charging problems
AC belt slippage would only squeal while the AC is running.

Timing belt off a tooth could make car overheat as it was have some interesting
effects on valve timing and possibly ignition timing.

I am unsure as to whether the alternator belt also has anything to do with
the water pump.  But I did have to take off all three belts (power steering,
AC, alternator) to get at the timing belt tensioner.  Did not replace the
timing belt at all, just removed the tensioner and replaced with new one.
Timing belt never went slack enough to jump teeth.

Also, the car only seems to overheat while at idle.  I noticed it on the way
home (6 miles).  When I was driving the temp gauge read lower than when I
arrived at my driveway and idled, whereupon it went right to red.

All I need now is the rain to stop long enough for me to deal with it.  :)
That won't happen, though, as we get 120+ inches a year here; so we're in
for it for the next few days.

Thanks.

ah hah!  fan belt!  I forgot about them; it's been so long since I had a car
that had one.

Sounds like there isn't enough air moving through the radiator when you're
stopped.  If you've an electric fan, make sure it comes on.

Sounds like it shooting to red a bit too fast;  wiring short?


Have you ever replaced the thermostat?  If you haven't and the car is more than
6 years old, then do it just for the hell of it.  They're cheap and it may
solve your problem.

Where you at?

From the abovementioned fact, It is most likely that your cooling system is
in poor condition, it only depends upon fast driving wind to cool off your
radiator, forget about belts, just have a thorough check of the cooling
system.
