Low temp guage/no heat

OK, I did it by the book: drained the anti-freeze, flushed the cooling
system, refilled and let it run, adding AF when the level went down. Go to
the top, and let it run, sealed the system and ran some more. Guage moved
to mid-level and the fan turned on.

But, when driving, the guage goes to clod. Even if I idle it for 10
minutes, and the needle climbs 1/2 way, when you start moving, the guage
goes to cold.

I removed the AF, replaced the thermostat, according to instructions and
the Haynes manual, and filled, 'burped' and tested again.

Same results. Any ideas?

Burp it again. An air bubble at the sending unit will give a false cold
reading. Does the heater put out hot air after it's warmed up? If so, the
engine is warm but the sending unit isn't contacting the coolant. Depending on
the routing of hoses, some bubbles can be hard to get out.

I was filling it through the filler neck, not through the bottle.

But, I also noticed, when it gets REAL warm (idling only) there seems to
be a leak from the water pump.
Water pump and timing belt on Friday...


Thanks!

I already passed on it. It's not that tough, SOHC, but I don't have the
tools to get around the motor mounts.

The last water pump I did was on a Honda V4. Two heads, four cams, solid
lifters, one gigantic timing belt. This was on a full dress motorcycle and
every piece of body work had to come off, except for the tail light.

What tools do you need? Many parts stores will loan or rent tools.,

non-interference engine I'd have tried it!
