Default Need help identifying Leaking Hose

Hello all,

I just bought a used 1998 4 door honda accord 5 speed.

Love the car but after a day driving it I noticed it was leaking coolant. Radiator is intact and I think I have found the hose that may be leaking. Car runs fine and keeps cool but when I park the fluid starts to leak before I shut down.

It is the hose with the markings YUSA Y809 markings in the pictures.

It connects to the side of the engine block and it looks like that is where all my my coolant is leaking out of.

Click the image to open in full size.

This one shows where it connects to the engine and where I think it may be leaking from.
Sorry I am only home at night so picture are dark.

I think it may be this one: Honda online store : 1998 accord water valve parts
Hose A #2?

If anybody recognizes it or knows where to find on a diagram or part number that would help immensely!!

Those are heater core hoses (to/from). Make sure the leak is coolant and ID the correct hose. A temporary fix is to cut/shorten the hose to a new end and reconnect. Usually enough slack to allow a short end cut-off.

good luck

TX has it nailed again.

All I want to add, if this is a 4cyl - the Gates PN for the hose is 19044 (valve to engine).

You might also think about replacing the o-ring on the dist. Two reasons, one pulling the dist - mark it so it goes back in correctly - makes it so much easier to replace that hose. Second, the oil build up leads me to believe there is an oil leak pass the o-ring.....two birds, one stone

Right on! Thank you for all the help and input. I'll probably pick up the hose tomorrow. I'll check out the distributor also. I think that build up is actually where the radiator fluid sprayed out, but something else to definitely look into. I cant wait to get this taken care of so I can start driving it and put on some fun parts to the car, ie intake etc.

IMHO - that is oil.....could have been addressed already and that is the "left over".....but that is oil. I'm hoping it is the o-ring and not the inner seal on the dist, still can be done but more involved.

Again, pulling the dist makes getting to the hose so much easier, adding a ~$3 o-ring?

To be sure, you can always clean the area with you choice of cleaners. After replacing the hose you can inspect the area and see if anything shows up.

Thanks poorman. I picked up the hose and will remove the distributor and clean it up. I should have just bought a seal too but will definitely do it soon. Also do you recommend permatex sealant on this hose or will it be good to go as is?

On the hose....just clamps.

Be sure to bleed the air out of the system - Honda's do not like to have air in the system. There is a procedure for doing this.

Ok, I got the hose in last night and test drove it and all seemed to be running well. The check engine light came on though after about 20 miles of driving. I didn't really bleed the system :/ Ive been googling around a bit. Tomorrow morning I should open the bleed valve and fill again until fluid comes out of that? Also Im going to auto zone to get the CEL diagnosed.

Be sure to set the heat to max - this opens the heater control valve so any air in the heater core can also come out.
