How many liters does it take to change radiator coolant

[@dimitristsampouniaris9245]

If you want to solve high temp issues , yu have to add a resistor in the coolant temperature sensor. You will have a smooth running engine running at 20 degrees celsius down from your running temp now.

[@petescarport]

Yes I have heard of doing this and definitely considered. I even think someone sells the resistor online. But I would love to get it running correctly like from factory if I can. Car always ran perfect temps up till last year.

[@williamillmilable]

If you're having engine running issues don't rule out O2 sensors on the check list. Keep bringing great content

[@petescarport]

Thank you very much. I totally forgot years ago when I did the obd1 scan the o2 sensor came up as bad. I need to change both out and see if it runs smoother. I bet it does

[@lilsprite05]

Man I see you never sold those black rims lol… I’m hearing a rattle noise on driver side rear.. sometimes the abs and plus that other light comes on. 98 s 420. I wish I could drop it off to you. I trust you more than these shops

[@GranMastaDee]

Hey Pete! - The rear hydraulic pump located in the trunk of my '99 S320, W140 crapped out, and thanks to you, I removed it and bought a used one on E-Bay. Now, the unit runs ( I can hear it humming in there) and operates the soft close doors and trunk again BUT the rear headrest release and remote lock/unlock are not working from the key fob or dash buttons. Any ideas? BTH: I have a friend with the same car as mine, and he was down to his last set of keys! - The good news is that he found someone locally ( Denver, CO area) that got him a new fob with a new chip for under $1000.

[@petescarport]

Yes check all your fuses in trunk. There are two and I don’t remember which ones but they control those two functions. Hopefully it’s a fuse.

[@GranMastaDee]

@@petescarport Yes # 9 - hold it for 30 seconds before putting it back and Pretty sure # 12 which is either burned out or good. Sadly, those didn't help. I may have to take it to that $220/hr. Stealership.Thanks for the reply Pete. If anyone out there is one their last key-chip let me know if I can help. MB stopped making them available.

[@LotuzKreationz]

Hey Pete I am having some issues with my w140, I wanted to know how I can reach out to you directly.

[@rosendodominguez-dw4rt]

GOOD JOB COOL 😎👍👍👍🤗

[@edvardsz3539]

Talking about fuel system and fuel pumps, I was quite suprised about the "dual" fuel pump system on early model. One of the pumps died on my car and it shut off. Like what? What is the purpose of the dual system then? Can't be that the massive BOSCH pump can not make enough pressure for a 3.2L engine...

[@petescarport]

It makes no sense to me either. This is why everyone swaps to a single pump system. Why buy two pumps when you can buy one.

[@calebhackney4850]

Did you ever figure out the shake/wobble this car used to have I’ve watch a ton of you’re videos and never saw the solution. My 1992 500sel has a wobble around 55mph and I was just wondering what caused yours.

[@petescarport]

It never fully went away but it’s going to be coming up in some videos. I want to change the brakes because I believe the rotors are warped causing some of the vibrations and than get the car aligned and tires balanced again since it sat.

[@marcosantoniocovarrubias6019]

On my s500 , I have a new power steering pump but there’s still power steering leak but I’m not sure exactly where it’s coming from

[@marcosantoniocovarrubias6019]

Think I can get some help ?

[@rci30]

Pete. Are you interested in a 1992 500SEL that has been sitting at my mother's for 15 years now. its relatively low miles at 136k. lots of history. lmk and I can DM you.

[@petescarport]

Hi thanks for the offer. Right now I’m not buying anything but may be interested in a few months. I have to make room and have a few parts cars I still need to move out.

[@rosendodominguez-dw4rt]

WAT WAS THE BIG PROBLAMS

[@redshot_8897]

Great to see alot of the W140's getting some love these days. I have a 99 CL500, and I'm getting a random misfire cose on 2,3,4 cylinders, changed all vacuum line,breathers,FPR, fuel pump and filter but still have code, any suggestions? Thanks

[@dimitristsampouniaris9245]

CHECK COILS

[@redshot_8897]

@Dimitris Tsampouniaris Hey thanks for the suggestion, but I did that. I swapped out all of the coils on bank 1 to bank 2, and the misfire didn't move to bank 2. So I'm thinking it's something specific that's affecting just 1 side of the engine.

[@petescarport]

Clean the MAF out or change. Also bad o2 sensors or clogged cats could cause this. What codes do you get when you scan.

[@redshot_8897]

@Pete’s Carport Hey, thanks, Pete. The codes I'm getting is P0302,P0303,P0304. I'm thinking that it might be cat, or O2 like you said because it's only affecting bank 1, so gonna check that next. Thxs

[@petescarport]

@@redshot_8897 yes that’s what got me thinking it’s something causing a shut down to one side. If it was an early model Benz I would say cap and rotor or the main bank wire. I had a short a long time ago that shut down one bank and a lot of people said to check cats.

[@dennisaunebakk8778]

Ayo my guy! You put the fuel orientation the wrong way! :D Otherwise nice work! :D

[@redshot_8897]

Yeah, he did. I took pictures of mine before I took it out a few weeks ago, and the arrow on the fuel filter is pointing towards the back of the car.

[@petescarport]

Oh shoot. Really? I was always told arrow towards engine. I need to fix this. Let me double check and thanks for the fill in

[@petescarport]

Lol. I just went back and checked and I realized I was talking about the direction and totally faced it back to fuel pump. I will fix this. One of the downsides to filming is you are focused on explaining but the benefit is you can go back and check your work.

[@MrJulioberas]

Fuel filter was installed in the wrong direction

[@petescarport]

Thanks already fixed same day

[@zazadarbaidze1504]

I use 5w40 viscosity engine oil in the M 104 engine

[@farerse]

Do you live in tropic or freezing climate? I'm pretty sure he lives in hot florida weather , then 10w makes sense.

[@petescarport]

Yup they recommend 0w or 5w for colder climates but 10w is better for extreme hot climates. I’m the winter I have run 5w40 but our winters only last a couple months in Florida. Than it’s 90f plus temps rest of year

[@farerse]

@@petescarport sounds right to me, and 40 is the viscosity at operating temperature which most people recommend for these cars.
