90 Accord EX

I blew a radiator hose today. It wasn't a main hose, but the heat cross
over (don't know what you'd call it), but it went from the engine to the
firewall. I've repaired the hose, but my car is still over heating. I'm
wondering if I blew a pump first, and that's why the hose blew.

Any ideas?

Cheers,

I assume you bled out all the air in the system when you replaced the hose?

Also, see if the fans are coming on. Honda usually puts the thermostatic
switch that turns on the fans somewhere near the thermostat housing.
Possibly fried it when the water was blown out. Or maybe it was already
dead and that caused the initial overheating that blew the hose.

 

Is the coolant full?

 

===================

That's a heater hose, it goes inside to the heater. If your pump was
blown, you'd have no drive, because the valve train blows when the water
pump shreds the Timing Belt.

You have to use good coolant, diluted with distilled water (or premix),
and the rad has to be full to the top, plus the reservoir has to be
filled half way full. Any time you do work on the cooling system, top up
the reservoir right away after you drive the first time.

If your repair isn't absolutely water-tite, the cooling system won't
build pressure, and your coolant will boil. Steam won't open the
thermostat or trip the fan sensors, so it's vital to have the system
full, and everything water-tite. Bleeding the air out is important too.
If your water pump has been boiled in tap water it might not have an
impeller on it anymore.

See your manual for the interval to change your coolant.
