    OMG, THANK YOU!!!!! I've replaced the entire cooling system on my vehicle and the overheating didn't stop until I replaced a $14 radiator cap! The reservoir was filling up and pushing out of the reservoir. Coolant wasn't flowing back in. You're video and knowledge saved my vehicle's life!!! Thank you so much!!! I owe you a beer!

    Thank you very much for this video. Also for those with overheating temperatures, take the thermostat and put in a pot with boiling water. The valve in the thermostat should open at the temperature engraved in the thermostat. If doesn’t open at that temperature, replace it. I also do this test with a brand new thermostat before fitting it to make sure the valve opens at the temperature marked on the thermostat.

    His diagnosis for my 1996 Geo Metro(mileage 165, 814) overheating issue was correct! I went out and purchased a $14.99 USD radiator cap from AutoZone. The radiator cap fixed the issue! I had previously purchased a brand new radiator, hose, and thermostat. Thank you ever so much for your philanthropy and kindness. If I lived near the Ratchets & Wrenches shop, I would definitely do business with you! I'm very impressed.

    Very true. Had this very issue and it caused overheating. It was the cap/valve at the overflow container though. Another odd reason can be the overflow container itself. Same result…
    Should be mentioned that many modern cars with a closed cooling circuit don’t have a radiator cap anymore.

    Holy crap, THANK YOU for this video! My 2001 Nissan Pathfinder was overheating and I couldn't locate the cause. I was about to tear into the motor and pull out thermostats and everything... then I closely examined the radiator cap. The rubber gasket had split so it wasn't holding pressure in the system. Coolant was expanding into the reservoir and causing a boil over. New cap, some "burping" of the system and we're all good 👍👍. I got a new cap for my truck too. Thanks again!

    Just about 2 weeks ago I had an issue with a different valve in the cooling system in my SUV (the thermostat). However, rather than the excessive pressure putting a hole in one of my radiator hoses, blowing a gasket or something else to aggravate the hell out of me, it just ruptured one of the plastic ends of my radiator!!!😑🤦🏼‍♂️ Being that I'm not willing to pay almost $500 for a new radiator and I didn't feel like wasting time attempting to find the right type of adhesive, I purchased a plastic welder and fixed the tank that day in less than an hour! So far I have not had any issues with my first attempt at plastic welding, which I am so far quite pleased with, however I have been welding metal for over 20 years and it seems to be somewhat similar to T.I.G. welding and Oxy-Acetylene welding/brasing (using filler rod).... I am certain it's not the prettiest plastic welding job that's ever been done by human hands, but so far it's definitely holding up really well!!!👍

    I ran out of coolant the other day sorry filled it and then a few days later I ran out of cooling again. My car started overheating so I had to pull over and walk to the local auto supply shop. I grab some coolant and filled up the radiator and the coolant reservoir. The car is still overheated and I couldn't figure out why and that didn't seem to be a leak or a noticeable leak. I then watch this video and went back to the auto supply store and got the radiator cap. It worked! The cap I had on my car was the original cap from 2005 so it was long overdue to be replaced. I would say if you run out of coolant make sure you fill up the radiator and the coolant reservoir and then replace your radiator cap because that'll be the cheapest option before you start throwing money away. Peace ✌🏾

    After many attempts to resolve the issue she decided to sell car. I let my wife use the car...at one point it overheated so badly the cylinder head warped. I went to get new cylinder head at a Dodge dealership. While there...a mechanic told me the timing belt might been improperly installed.
    Sure enough...I found the belt timing was off by one notch!
    Corrected it...with new head installed...the car ran great!

    And this comment is in regards to the tip about boiling your NEW thermostat. To verify it. Works.
    Unless technology has advsnced or something. Ive both been told snd read in factory service manuals. That have all stated the same thing.
    Boil it only to verify its faulty or needs replaced. Never boil a new one.
    Basically once you boil it. To verify if it opens and shuts. It now must be rrplaced. Ive always followed this and never had it be in corerct. Ive also never encountered anyone. That can disprove it either. So. Ne ways.

    Quick question Bro. When I start my [1998 Honda Accord 2.3 4 Cyl ] when cold, without radiator cap it blows water out like a quick throw up ,.Note: car over heats...What could be the issue. ?

  • @altri5842

    hmm my car has a coolant problem where it over fills the reservoir tank and bubbles. im assuming it's a headgasket or warpped head issue. i also replaced the radiator cap multiple times with new from japan and aftermarker from autozone. i really don't know what to do

    Nobody seems to talk about coolant that boils below the spec temperature. At 20K miles my coolant was still testing at 40 degrees below zero but boiling at 220 F, even though the gauge was far from red/overheat. steam would bubble into the reservoir and push coolant too. That left an air gap in the system because not all the coolant would get drawn back in from the reservoir. There are no perceptible leaks and the system passed a pressure test and combustion gas test.
    Replaces the radiator, cap, thermostat - no solution.
    Replacing the coolant solved this issue that even a pro mechanic shop was glad to misdiagnose.

    Bro, I put a new radiator, new hoses, new cap, new thermostat, I thought problem fixed, I replaced the entire system, drove fine for a month or two, now out of no where, it's heating up again. Any ideas? I started to smell a funny smell, coming through the AC, my engine dip stick, was showing no oil, but I did the oil change not long ago. So, I'm done with Nissan Altimas, been a pain in the ass owning one.

      well if its a bad enough leak it will burn up inside your cylinder or if you take the spark plugs out sometimes it will actually be covered in liquid. could also have a leak inside your car via the heater core. also lets say you have a cracked cylinder head it will go up inside underneath the valve cover and then get sucked back into the intake via the breather hose or a bad pcv. but you'll usually get milky substance underneath the oil filer cap. good luck.

    What if there’s no radiator cap and just an overflow tank that has the plastic cap? I changed the water pump and. Thermostat and had the radiator checked and my Chevy Equinox is still overheating at idle when it’s driving it’s fine it cools down my mechanic nor myself can figure out the problem

    Just got a 97 accord. Was overheating only after driving for 45 minutes or longer. No issues when driving but when I got home. The overflow would be boiling off
    After cooling off I checked the cap and it was broken and a piece was stuck inside the radiator.
    Getting a new cap now so I'm praying it was just this.

    • @TheMaroney

      Also the car was backed over by a construction truck and a wiring harness (grounding harness) was destroyed and the cooling fan ground was broken off. Amongst many other grounds.
      Spend the day rewiring the harness and seems to be doing well.
