Well, its odd to me anyway. It started with a mech sealing up an oil
leak on the front crank seal. He said I really needed a new harmonic
balancer, which was scored all the way round on its hub. I have
little understanding of the actual mechanics of what he was talking
about, and I didn't see it. [I couldn't form a blueprint in my mind,
unless I see how the parts mate]. He got the small oil leak stopped,
but I've had intermittent coolant leaks ever since.
First it was cause the overflow tube was left off, then it was the
lower hose wasn't tight. I'd stay dry underneath for a few days,
after I fixed these things myself, and then I'd see small amounts of
coolant on the concrete, about every four days, over night.
Once when I was fueling, and came back out from inside the QT, she was
running out pretty good from underneath. I got down on the ground,
and it looked like it was coming out in small drops right below the
water pump, or timing cover housing. I took it in to see if they
could see exactly where it was leaking from. He said he couldn't tell
for sure either, he didn't think the water pump was bad, [however he
could tell that?], and talked me into putting a free $20 of Wynn's
coolant system treatment in her. I don't believe in using stop leak,
but he convinced me this was different, and absolutely would not clog
anything, including heater core.
Everything was fine for a few more days, then I notice the first drive
of the day she wants to heat up. The temp gauge just keep rising
steadily. Way over where she normally runs. Out of coolant? No.
Losing coolant? No, not that I can see. None in the oil, [that I can
see]. None coming out the exhaust, [that I can determine]. None on
the ground. But when I turn on the heater full, and fan full, just
before she starts to hit red line on the temp, and she goes back to
normal heat range real quick. And stays there, regardless of what I
do with the heater and blower. If I make half a dozen trips that day,
its the only time she does it, the very first trip. She don't do that
again till next morning! Never again in the same day, even if she
sits off for several hours.
I replaced the thermostat, cured it. For the first day at least.
Now its back to doing the same exact thing. One guy says I have air
trapped in the block and intake coolant ports. That I need to drive
up on some ramps, [to get the radiator higher than the top of the
block, loosen both the coolant sensor on the intake, and coolant
sensor on the block to bleed the air lock out. [I don't know].
Another says I have a bad head gasket, or seal.
