I have a 95 accord that keeps blowing upper hoses
I've replaced the thermostat, rad cap and flushed the radiator but it keeps building pressure in the cooling system, it's never run hot and it's not showing any of the symptoms of a blown head gasket. I dont know what else to look at

GhostAccord

Keep an eye on the overflow and see if the fluid level rises with engine temps. I know you said you replaced the rad cap but are you sure it's working? The overflow tank is where the fluid is supposed to go to relieve the pressure of expansion.

Is the radiator cap Genuine??

bigdaddycustoms

the resivoir level isnt changing and the cap isnt genuine its a stant 16lb I'm gonna try another cap tomorrow

nus_dogg

Yeah, try a Honda Cap.

GhostAccord

Well the PSI is in range. Honda spec opening pressure for the rad cap is 14-18psi. But if you don't see any level change in the overflow I would try another cap. OEM if possible.

bigdaddycustoms

just in case the cap isn't the issue is there anywhere else I need to look? trying to get a checklist for tomorrow

GhostAccord

That's the only thing I can think of.

bigdaddycustoms

well i think the head gasket is blown, replaced cap with oem and now I'm getting air bubbling/steam in the overflow. that sucks

bigdaddycustoms

probably gonna pick up a f23 and be done!

dleccord

did you let the car run with the radiator cap off for a while to see if bubbles go up?

Put the front of the car on jackstands.
fill it w/ coolant w/ the bleeder valve open until a steady stream of coolant comes out.
close valve.
fill overflow tank to proper place.
remove radiator cap. start car w/ the heat on high and then when coolant comes out of that immediately put the cap on.

was that your method of getting the air out?
