While I didn’t do it that way, I’d suggest installing the lower radiator hose before placing the new radiator back in the car.I think the crux of this repair is being able to break the electrical connections.Used $1.50 funnel with electrical tape to seal radiator cap opening.ī.ğollowed Eric’s refill instructional video ( 2 cycles of Radiator fan) Refilled cooling system with standard green antifreeze and distilled water.Ī.

Once I had done what I could to clean up the cooling system, I started the repair – removing/replacing the old radiator. Remove and save drain petcock as a spare. Started up engine & ran until water was clear again.Ran until water coming out of the Thermostat housing was clear.Inserted hose into radiator, hose was connected to hot water tank.– Followed Eric’s refill instructional video ( 2 cycles of Radiator fan) Added Radiator Flush and water to refill cooling system.– Followed Eric’s refill instructional video ( 2 cycles of Radiator fan), This also insures water circulated through engine The instructions were a pain with many steps: I bought a quart jug of Zerex, Radiator Super Cleaner. No point in installing a NEW radiator with junk in the engine and then flushing the system – only to run any dislodged gunk through the new radiator! [the thermostat repair suggested a fair amount of hardening of the arteries (calcified deposits) inside the cooling system. So first step, for me, was flushing the cooling system to remove any built up gunk. I might do a step by step on that later when I put it back on. Oh and I had already taken the lower shield off. The thermostat was replaced after the water pump repair and before this repair. Also bought new upper and lower hoses and new clamps. I ended up buying a Denso radiator because Denso is one of the OEM manufacturers. Asked a bunch of questions here, watched Eric’s radiator videos and took my time buying parts (finding the cheapest/good ones). I was rather slow and deliberate with the process. This repair was more like the Civic, so hope this adds to depth to the knowledge base for anyone that comes along in the future? This is the least I can do to pay back for this great resource. Eric’s videos on the radiator replacement on a vintage Civic and his Accura Vigor, are helpful. Hope this isn’t preaching to the choir or so grossly redundant as to be an annoyance. OK, so here is how I replaced the radiator on my 1989 Honda Accord, 5-speed, Lxi, with the fuel injected A20A3 engine.
