04 civic LX, overheating, list of parts replaced
 

Hey everyone, sorry if this is redundant but I'm at a loss, I have replaced my thermostat, gasket, coolant temp sensor, radiator fan, relay, fuse, water pump, and radiator. Car still over heats. There is no coolant in the oil or any smoke coming from the exhaust. I am at a loss on what to fix next or if there is something I missed. Any help would be great

Use OEM parts?
Is the interior (climate control) heater working at idle and while driving?
Did you bleed air from coolant system per service manual?

With all the parts you replaced it points to the head gasket as being suspect. Do a Block Test and/or an Ezone style leakdown test.

Interior climate control is not working, barely blowing air warmer than outside temp, bled air out of radiator as much as possible, waiting for it to cool down to night and try to re bleed radiator but im guessing head gasket is toast.

all of these parts were a waste of money.....you have a blown head gasket

Kinda figured that from the start but didn't spend any money on the parts because they were all warrantied from ea skier this year. Car is having a very hard time starting today after letting it sit, ran it for about 4 miles all was good and now 4 hours later it doesn't want to start.

I had a similar issue with 2002 LX and everyone said, "it is the head gasket". Well, it wasn't. Rather, it was caused by air pockets in the coolant system, when my thermostat was replaced and the coolant was flushed.

To remove all the air from the cooling system, I used the "Lisle 24610 Spill-Free Funnel" which I got from amazon. I was surprised how much air came out.

I use a Garmin mechanic live monitoring system to check the health of various systems as I drive and my coolant temperature is between 183 and 205, cooling fan is activated at 205 and turns off at 200 with coolant temperature dropping to 196.

I haven't had any issues since it was flushed properly.

OP: with all the parts replaced it's assumed that if you have the skill level to or a mechanic replaced those parts...then a proper coolant system bleeding was performed.

Are you losing coolant externally or internally? Have you or a mechanic performed a pressure test to find possible external leaks?

I would start with a pressure test and a block test (both testers are a free rental at Autozone or O'Reilly's) Block Test fluid is $10. Start there and if no leaks are found via pressure test and block test is negative: blue test fluid remains blue...then do a coolant system air bleed:

Raise front end on jacks as high as possible
Set climate control to max heat and fan off
Can (optionally) use a funnel as David mentioned placed in the radiator neck
Start engine and let idle until rad-fan engages twice
Turn off engine and use a rag (to avoid burns) to put rad-cap back on

its a 4 banger.... go for the head gasket job.. just get the head checked for cracks and warpage... other then that watch some tutorials... you could probably do it in 3 hours..
