Good to hear! Glad you could get it done. Thanks for watching

Thanks, John!

I hope it went well, keep it on the road!

Thank you for watching! Glad to know O'Reilly has them

You are welcome, thank you for watching

Awesome, hopefully it all goes well. Thanks for watching

Thanks Mr R!

After watching your vid, I purchased an OEM thermostat and blue coolant (from a local Honda dealership) and that spill-free funnel (from AutoZone) and successfully replaced it; the temp gauge is running steady now...thanks again!

I agree on the Asian coolant, however this car has already gone to its final resting place lol, I used what I had. Thanks for watching!

I use Toyota Pink coolant in my Honda. Same coolant type though. Also,there are many aftermarket brands that offer P-OAT coolant.

​ mlo

You're welcome

Green universal coolant works, this car was trash and is already gone. I would use whatever you feel best putting in. If I had a nice Civic, I would use blue as well. Thanks for watching!

I wanna drain mine too but if I wanna put blue coolant do I got to change the radiator to do so

@@RiggsGarage Did it turn out to be more then the thermostat and radiator?

Honda coolant is basically a phosphated OAT type coolant like most Asian carmakers use. There are many aftermarket brands for Asian coolants available,not just the dealer. Zerex,Recochem,Peak OET,Beck Arnley,Aisin, Pentosin,etc. I use Toyota Pink in my Honda,same coolant formula,different color. I prefer Pink color. No problems.

As long as is organic maybe change it more often like every year

Hey man! You guys catch anything that night?

@@RiggsGarage we didn’t

Take off your radiator cap if the coolant isn’t circulating it’s your water pump . Also run your heat to open the thermostat. If that doesn’t work you have a blockage somewhere in the lines . I had to rebuild but it solved the problem

Without seeing it, I'd guess it was a huge pocket of trapped air escaping?

The thermostat won't make bubbles appear. That means there is air in the system somehow. If the thermostat is opening, your radiator and upper and lower hoses will be hot. Hope this helps you get there.

Dang Yeah, they are good at killing head gaskets. Definitely bleed it to rule air in the cooling system out

The overflow is just an overflow tank, not a part of the pressurized system to be bled. Bleed the system from the radiator top, once that's bled put the cap back on the radiator and top off the overflow. Sounds like you have a leak somewhere. Might Google around to see where all of your coolant hoses are and check them

Definitely check for leaks first, that's how a heater usually acts when your system is leaking / low too.

@@RiggsGarageI have this same problem to but the heater was working great while still overheating for a while and then recently when I turn the heat on so my car wouldn’t overheat it just blew cold air sometimes when I turn on the heater. Replaced the thermostat and coolant sensor. But still overheating. The radiator fan doesn’t kick on either. So my theory is it’s the fan or the coolant system need to burp/ bleed. Thought?

@@RiggsGaragealso did the combustion test. The blue fluid stayed blue so I think we’re good on that part.

Depends on how low, couldn't hurt. Now the main question to answer here is why is it low???

@@RiggsGarage that is a good question lol. It’s been sitting for about 3 years, but I haven’t seen any coolant leaks since I started it back up.

@@jadizzle check it out and be careful man Don't toast your engine lol

@@RiggsGarage do you know how much coolant I need to drain and replace completely?

When coolant temperature drops, the fluid shrinks causing a vacuum, that sucks it in the same as hot pushes it out

Is it a threaded cap? If it is and it's a pressurized overflow, that is an issue because the cooling system needs to be pressurized. I don't have that year of civic so I can't go look at mine

I have a 2001 Honda Civic. and yes it is a Pressurized system, it needs the Resevior/overflow cap.( little white Threaded one.)

It is in the video description. Thank you!

Fill it to the full line

There is a lot going on here. Without being there I can't really help that much, except I would say attack one problem at a time

@@RiggsGarage I ended up figuring it out, had some wonky issues because my cluster wasn’t working/communicating with my ecm. As well as the drive circuit going out as well. Got a used cluster and it solved everything as of now.

@@codydavis7030 Heck yeah! Glad to hear!

Thanks man appreciate it, I’m glad to be rollin again for now!

Yeahhh......😬

Hi, what do you mean too over pressurized? Like it's building too much pressure? Does it overheat? How do you know it's over pressurized? Lemme know

@@RiggsGarage ok so it doesn’t overheat but after driving it for a while it will push some fluid into the overfill and not suck it back into the radiator it also stays pressurized for hours I have drove it then parked it and let it sit for fourteen hours and then come back take the radiator cap off and it blow coolant everywhere and I’m unsure why help pls

That is what mine just did. Was still pressurized when taking cap off and it’s been over 15 hrs since driving it.

Maybe your rad cap has too high a pressure rating. Caps are designed with a spring to allow coolant to bypass the cap seal and flow into the reservoir when they reach a certain PSI. Research what your car requires for a PSI rating and verify yours.

@ManBearPigBear You are right though that is why my uncle said the same thing he has been a mechanic for more than 20 years

Haha it was missing on this car, it was a piece of junk from one of my family members. That cap is not needed technically because it's not a pressurized piece of the system, just an overflow

amzn.to/3UwddmD

Yeah this thing had been filled with green universal coolant over and over as it leaked. It will survive without magical Honda juices 🤣

@@RiggsGarage, yeah, that’s what usually happens. Not sure what what’s special about Honda’s blue coolant or how well it plays with others, but I have learned my lesson on mixing coolant types in ford, dodge and GM!! In any of those, If it says use a certain thing, then you better do it or pay the expensive consequences. Enjoyed your video, though. The most comprehensive one on Honda’s I’ve seen. Even better than the one ETCG put out way back. Thinking of subscribing.

@@fomoco300k thank you! Yeah I'm thinking of dexcool in the GM cars, destroying cooling systems when mixed haha

after 13 years of refilling my 2003 civic with cheap old walmart antifreeze that car still doing great ( a couple accidents made me replace radiators). Maybe the honda brand antifreeze keeps that engine running cooler, who knows. But burping is the way to go, you can add some distilled water too and the old civic will be happy if its just to top it off and burp it. 'nuf said.

@@fomoco300k Honda coolant is a P-OAT coolant. Most aftermarket brands offer it. Zerex Asian Vehicle,Recochem,Peak OET,Pentosin,BeckArnley. I use Zerex Asian Vehicle Pink in my Honda. Same coolant different color.

There is an Amazon link in the comments. Also at O'Reilly I think

No, that is not a significant enough angle to uncover the oil pickup. Should be just fine 👍👍

@@RiggsGarage Thank you.

Can you drive up a hill,mountain

It can be open or closed when bleeding coolant system, overflow does not hold pressure

Could also be low coolant

Clogged heater core

That's not normal. Could have a leak or possibly head gasket is allowing exhaust into the coolant. I'd recommend pressure testing your system and checking for head gasket leaks

@@RiggsGarage I appreciate your response! I’m going to look into that.

If pressure tests pass, the heater core may be plugged with gunk. If your car smells a little rotten in the morning, that is a tell tale sign. You can unplug the coolant hoses from heater core and use a connector to reconnect the hos es directly together with it. Bleed the system again and test and see what happens after its bled overtime time

if your car overheated recently and it still runs with apparant normalcy, don't be fooled it sounds like a head gasket leaking enough to put constant gases into your cooling passages. after an overheat and a couple trips where it seemed still normal but no, the longer I drove it the more bubbles would come out of the radiator filler with the cap off. I pressurized the cylinders and cyl # 3 was pushing coolant out the radiator filler tube. more clear it couldnt be! and it was still running. I removed the cylinder head; had it resurfaced and worked the valves and seats to non-leak status and put it all back together. after 2 and 1/2 years later it competes with lumborginnis out on the highway .. I'm proud of my civic! an 18 year old car doing like a new one, that is quality. (09/26/2021).

@@pistolp9809did you ever end up fixing it? If so how. Having the same thing happen to me after replacing thermostat. Not a head gasket leak as none of my fluids are mixing and fluid levels are staying the same and the bubble don’t increase when revving. I’m thinking it’s a exhaust leak

Make sure you find out where the coolant went, might have a leak somewhere. Be careful 👍

Yes it can if there is a bubble in in the icav

@@RiggsGarage when i cold start the car it surges a bit also when driving in gear then and putting it in neutral the rpms dont catch them selfs

@@javierchavez7167 could also be a vacuum leak or something. Is it throwing any codes?

@@RiggsGarage no codes and 100% sure no vacuum leaks

Maybe if it was not a ragged 200,000 mi $1,500 car sure lol

It varies depending on the car, but after the car is fully warm and the thermostat is open I just let it run for 10 to 30 minutes with that funnel on there and just let all the air work its way out

@@RiggsGarage thank you. I was not not letting Honda Civic run more than 10 min!

Are you referring to the funnel? It comes with multiple different radiator cap adapters and you just need to figure out which one fits your car. The kit has a lot of them and so far they fit everything I've worked on.

Not quite sure what you mean

@@RiggsGarage i just realize it was the universal bleeder you bought.. I thought it was original cap

@@Papisartee haha got it, yeah, The cap is part of a kit

Could be several things including a head gasket. Definitely get that checked out
