Smelled, then saw coolant on passenger side floor mat. Suspect either failed heater core or failed hoses/clamps. Should my next step be to disassemble heater box for a closer inspection? Expecting to find failed heater core... Thanks. Maverick-iac
Yes, it's a non-AC car, and I have already found some helpful instructions on how to replace the heater core on this forum by searching for "heater core." Thanks.
If you can't get to it right away and want to still drive it you can connect the two heater hoses together and by pass the heater core . IT'S NOT THE RIGHT WAY ! but it will work in a pinch..Good Luck
...now would be a good time to make sure you have ...good grounds... i would suggest...ground straps... i have...one on each head...one from bottom starter bolt to frame... batt. grounded to pass. head. ...Frank...:Handshake
A bigger cooling sys. problem Well I replaced the heater core 2 weeks ago using all the great help from this forum. I thought the problem was solved. Now I find coolant starting to leak AGAIN on the passenger floormat. I suspect there is a bigger problem. The new heater core is from NAPA, brand new. The cooling system was flushed in July at Jiffy Lube. Coolant was clean and green with very little sediment. The car is not overheating. With the new heater core, the mechanical temp gauge tracks exactly to the thermostat temp. One other clue: After driving the car for a few miles, then stopping the engine, there is a strange gurgling/bubbling sound from the cooling system. This sound was evident before installing the new heater core. For those diagnosticians out there, what tests should I do next, and what root causes should I be looking for? Thanks.
I was thinking thermostat or radiator cap. Also check clamps and hoses. Also radiator itself for pinhole leak perhaps. Hope this helps. Robin
