    I had a shop install struts for me and the owner told me to get quick struts that they work the best so when I went to pick up my vehicle it made noise so owner said don’t know why making noise so got new ones same thing happened then said they just need to break in so I researched quick struts found out the spring comes smaller longer and worst things to use. So now I have to get oem struts which are way more expensive cause I believed this man so Ray I’ve been watching you and Mr.O and started buying me tools and I have been doing my own work and so far I’ve fixed my own money light, replaced my passenger half shaft, both front wheel bearings and sway bar links so keep up the great work👍

    Ray that vehicle had a bleeder valve in the same housing you were replacing. When pouring coolant you opened up that bleeder and once the coolant began to pour out in the bleeder you close it up and finish filing the coolant in the radiator. Once you finish, put the radiator cap and start the engine and it won’t overheat because of an air bubble in the system cause you already bled it at the beginning. It’s something that could be very useful for you in the future if you receive other Caravan with the 3.6lt Pentastar engine.

      I've found it doesn't work 100%. Despite bleeding it with that bleeder after I replaced the thermostat on my sisters van, there was still an air bubble stuck somewhere, probably behind the thermostat, that caused no heat and the engine to get hotter than usual, until the thermostat opened, after which, the bubble purged itself, and the next morning it needed a little more coolant and then heated up normally and had heat.

  • @jimsmith5148
    @jimsmith5148 ปีที่แล้ว +58

    No, spring pressure has nothing to do with it; in this case, it practically does not depend on temperature. Inside the thermostat there is a certain substance similar to paraffin, which expands greatly from temperature, pressing on a thin rod that sticks out of the thermostat, the rod overcomes the resistance of the spring and opens the thermostat.

      My LS2 had a flat rubber gasket. It tore 3 times and would wedge itself in between the flat part and the copper part. Twice it stuck closed. The third time it stuck open and it wouldn’t heat up. Of course, it stuck closed in the summer and open in the winter. I drove 5 hours to Atlanta in January with it open. I had tepid heat occasionally. The first time it stuck closed I was in a traffic jam…in Florida…in July. It took me 3 hours to limp it 2 miles home.

  • @Zanthum
    @Zanthum ปีที่แล้ว +35

    I could be wrong but I'm pretty sure the thermostat uses a wax motor mechanism to open and shut. A small slug of wax tuned to the desired temperature expands when it heats up and melts and presses on that central pin pushing itself towards the spring opening the valve. I think that the golden? capsule in the middle of the valve plate of the thermostat is where the wax is.

      Yeah, not a bi metal spring. Wax has a strange characteristic in that melted wax increases greatly in volume compared to solid wax. Also, it is easy to produce wax that melts at any temperature desired within reason. So, a great little engine and one that won't fail and can be only let down by the mechanical parts.

      I normally find Ray pretty knowledgeable about all the different vehicles he works on. To hear him speak of a bi-metalic spring on a typical thermostat gives me pause. This is a basic part that is normally explained in a high school shop class. They've been building them this way for over half a century. I feel a bit let down today... I guess the important thing is finding the faulty part, not so much how it is supposed to work.

    Hey Ray! The way that thermostat actually works isn't a bimetallic spring and the spring weakening, it's a wax motor (like a lot of thermostats). The brass cartridge in the middle has wax which expands as it warms up, and pushes out that little pin - which pushes the thermostat open against the spring. Same end result, but the more you know! Does look like the missing seal was the failure mode though, as excessive cooling would suggest the thermostat was being bypassed rather than sticking closed.

    @Rainman Ray's Repairs, nice job. I did the same job on our Caravan last year. Just be glad this wasn't the notorious "3.6 Pentastar tick/tap engine noise"...💀I replaced a camshaft (cam lobes were shredded by rocker arm frames) & all 48 rockers & lifters, talk about a PITA, especially for a "non-mechanic"... Back to the thermostat, the vehicle didn't exhibit shift issues but the temp hand never even made it to the mid-point. I think the temp is supposed to be around ~202-205°F, that's almost boiling for water of course that's why it's important to have a proper mix of coolant. As a kid, I used to think "anti-freeze" was just that, it was to prevent freezing but it also helps prevent overheating (& corrosion) as opposed to running straight water in the system.
    I wondered if you were replacing the hoses at the same time. I used one of those "coolant fill kits" with the adapters & bucket that fits atop the radiator. It was crazy how much air was in the system, the coolant was bubbling up in the "bucket" & finally all the coolant just went in... As for the type, I did get the recommended type. The coloring/coding etc., gets confusing because then they claim there are OAT and HOAT types and "can't be mixed" etc... I'm just wondering why can't we just stick with one type instead of trying to match codes/colors and so on... I mean oil/trans fluid is simplified enough, why can't coolant be...
    One thing people really need to be conscious of is the toxicity of anti-freeze/coolant not only to animals but humans! Definitely need to protect the skin & try to wash it off as quickly and thoroughly as possible. "Anti-freeze" damages the organs severely and whilst we're not talking about drinking it, many times we don't think about just how toxic chemicals are if we experience no immediate adverse effects.

    • @coolantkid3428

    a suggestion, you should probably recommend that the owner swap out that oil filter adapter housing to the newer style housing and filter, as that one has a tendency to break the oil filter bypass valve and get lodged in the filter causing the oil to continuously bypass and not filter... not good for a filter. :P
    I recommend the doorman 926-959, as it's been machined out of aluminum, rather than the OEM 68105583AA to 68105583AF housings, as it also is eliminating the issue with the plastic getting brittle and cracking as well, which is also an additional issue with the housings. it's about 30 mins to R&R.

    Step One in troubleshooting: verify that the reported problem exists and is the actual problem. Did we run the engine until the cooling fan came on (to verify its operation) and then take the car for a drive to see how the temperature gauge reacts? Sometimes backflushing the cooling system will solve the problem. If not, at least you won't be working in antifreeze when you replace the thermostat.
    He didn't tell us anything about the three "failed" tire pressure sensors. Since Florida just experienced a cold snap I'm sure that a lot of stuck open thermostats and underinflated tires were revealed. Since the lone reporting sensor is showing 38 psi the odds of the pressure exceeding the sensor maximum are greater than three sensors failing at the same time.

      3.6 pentastar thermostats are about as common to fail as a 4l60e transmission or 6.0 head gaskets. The new part is less than $30 from the dealer and replacement takes less than an hour. These vans are approaching or exceeding 10 years in age and replacement is really a no brainer. a P0128 on a pentastar equipped Chrysler will be a bad thermostat 99.9% of the time.

    You have leaves.....
    Earlier just before the rocky mountain winter, my 04 Astro started not getting up to temp and threw a p0128 code. I took it to Jim's shop (a local mechanic) and told em to fire the parts cannon and wing a thermostat at it please. Next day I picked it up and the invoice for labor said "Fire the parts cannon and change the thermostat" :-) I might have tried but it look like a pita on the van and the temp sensor is accessible from the dog house on the rear drivers side head, if I was wrong. Well I was right and now it's full blast winter here but my van is toasty and geting up to 180 degrees now.
    Moral of the story - it's the thermostat.
    Unless it's not.

    Greetings from the northeast, hi Ray this spring on the thermostat only applies pressure to the valve, the brass piece in the middle has a wax motor which is very simple when the wax is heated up in the motor it pushes a piston out slowly and that's how the thermostat works very simple very ingenious and very reliable. You can also find wax motors in your dishwasher and I also found one in a diesel engine in a backhoe that once it heated up changed the timing.
