1998 honda accord coolent lose with no leak

I have to refill or top of my radiator at least 1.5 time a week.
80-100 miles. there is no fluid leak outside the engine. where is
the coolant going? the car is sometime hard to start especially if i
park it nose high.

help!

 

Check to see if your oil foams up.....(coolant in your oil).

 

Start with getting the radiator cap tested. If its not holding pressure,
too much goes out into the overflow and gets pushed out onto the road. If
that's not it, then start looking at the more expensive stuff like water
pump, leaky radiator, head gasket, etc.

A small leak will not show up when the engine is hot (evaporates off almost
immediately), but can still amount to significant losses in fluid. Look
carefully when the engine is cold for any droplets or discoloration around
the engine and radiator.

 

sounds like head gasket. look for bubbles in the coolant expansion
bottle when the engine is at full temp. make sure you eliminate other
leak sources before surgery though. chemical test is good. check the
coolant pump from under the engine.

fyi, heads usually go because of overheating. and overheating usually
occurs because the radiator cracked a while ago. be aware of that in
future and replace pre-emptively! and make sure that if it's the head,
that the person doing any replacement does NOT use any abrasives in
cleanup, and does NOT skim the head unless it's warped. google this
group for info. and finally, sometimes, economics of engine replacement
are more favorable than engine surgery with the great price of japanese
jdm engine imports.

 

almost never happens on a honda. head gasket is bubbles in the coolant,
and that's pretty much it.

 

Probability pretty low.....ack!

 

If you've checked for leaks (hoses, heater core, water pump,
reservoir, rad cap, etc) and found none, then at that rate probably
the head gasket.

You can have the coolant checked for exhaust gas (test strip or
sniffer) if visuals don't show.
