So was all excited two nights ago to possibly turn the car over and set in the rings and actually *DRIVE* my freaking car, but I noticed that the coolant line running into the heater core outlet on the firewall was seeping coolant after i filled up the system.
I'm in day two of trying to fix that, looks like for now I'll just take both those hoses and bypass the ****ing thing.... so frustrating
this pic is AFTER night # 1 of messing with it... i've since tried a little bit longer hose to take some stress off it, plus also tried a stronger/better clamp.... still dripping
Lots of these heater core and IM hoses are formed to a specific shape, for good reason. Universal (non-formed) hoses like that one will create "weird" angles at the fitting when installed, sometimes causing a leak. I would also say check the hose barb isn't deformed or out-of-round.
Order yourself a new OEM clamp with it as well, they are easier on hoses than the worm gear clamps and provide mOAR even clamping.
the brass part got beat up pretty bad on engine removal (hose was fused on there), bent it back to where it looks pretty round like it should be, but who knows... i think someone told me @steelmatt6 just went through this as well
I just went through this before my car was down. I tried to remove the hose and it was fused like yours and it wouldn't stop leaking even with a couple off different hose and clamp combos. I had to just bite the bullet and replace the heater core. It sucked but it was leak free after that
If all else fails, spend some time with a strip of emory cloth cleaning up the heater pipe. The gunk that accumulates after a decade or two is evil, but needs to come off to make a good clean joint with a rubber hose. I give my radiator hose fittings the same treatment every few years. Shiny fittings make for happy hoses.
So got the OEM hose coming off the firewall's brass tube, got the OEM clamp on there and then hooked the other side to a barb connector to the hose coming off the coolant pipe (the SC gets in the way of the length of the OEM hose reaching all on it's own)
just filled the coolant system again, it's got the afternoon to settle in and see if i am still leaking fluid or not.....
if it's not, and damn i so hope so, i'll start the car up tonight.... I've already got the distributor and fuel pump unplugged to get some oil pressure going to initially set in the rings...
Monday night I did do the initial break in of the pistons (no distributor, no fuel pump) and then connected those back up and fired the car up... she fired up right away!
- coolant line from other side of heater core is dripping where it meets the head under the VTEC solenoid, gotta fix that
- after idling for 20-25 minutes i didn't get to see/hear the new cooling fans turn on
- fuel rail was leaking where the line from the fuel filter comes in, I tightened it to the point where it stopped, but i'd like to get some new crush washers for that
yesterday i got super sick and spent all day in bed, today isn't much better, so next step may be a few days
