I know this has been discussed a bazillion times, but hang in with me. From what I researched the eurocharged, plm, and code 3 are the the heat exchangers out on the market for our cars. The eurocharged is liquid cooled and the PLM is air, but the code 3 I do not know. Anyways, I am deciding between the PLM and eurocharged, but am leaning towards the eurocharged because it will keep the stock h/e and be an addition making things cool faster. The PLM from what I understand goes in replaces the stock h/e but is bigger (correct me if I am wrong). So, is there any benefit going with one versus the other as far as cooling is concerned or is it a preference thing? Also, does picking one h/e over another dictate what king of pump set-up I will run?

I was set on the cm30 but the more I read about all the conflicts I just do not know and I have a massive problem with procrastinating!

I am not going to be doing a trunk reservoir, but only the h/e and pump and possibly split circuit jiggly a bob.

Anyways, have any of the following pumps been proven to be better, cm30/cm90/meiszere? I know that some flow more, but I read that it can be a hindrance to the system.

Please help me the 55k gods.....

Go with the EC h/e and meziere pump and you will be happy with the results

Can someone gives the SN number and model of the Meziere pump that will fit? A link would be an advantage

I thought that the E/C replaced the OEM H/E and was bigger. Does it go in series with OEM?

Agreed

wp136s. Look on their website under remote electric water pumps

Let me add two things to make this system give you max performance.
1) Wire pump to run when key is on.
2) Seperate your I/C system coolant from your Engine coolant.

now we are talking. do you want to borrow my 04 cobra to see how the cooling system should have come, stand alone only. by the way cobra heat exchangers are only $289 and are dual pass through which is what I am going to run on my e55 with a meziere pump.

That is correct, the EC HE replaces the stock one.

ahmad0658

Thanx a lot for the model ...

I did the Eurochagred HE and it does replace the stock HE.

+1 on Exotics post above. Wire to run on key or she will turn on when the ECU feels like it. By then most time, it's piping hot. Also separate from system FOR SURE. Its cake.

Now I haven't dealt with him in years but when I did, Code 3 offered some really high quality stuff. I liked the idea of just one massive unit compared to piggy backing both together although I have had both and there was no difference in the 2. Again, the one I bought years ago from Code 3 bolted right in place with no hammer mods or drilling. It's liquid too.

On the pump, I would 100% go with a Johnson 30 pump or equal pump. I just think my 90 is too much flow for the system so I say go 30 first. It's lots easier to bolt in as well. 90 is a pain. What conflicts where you referring too? Just was curious.

OH last thing, if you are not gonna run trunk res, then you will need some type of tiny unit in which you can fill the thing up. EVOSport offered a kit with a little tiny res in which you could keep an eye on levels.

Not sure if EC or the Code 3 offer that. If you don't get the mini res, they tech can still fill it and then seal it off but you will never know if you have a bubble that causes the level to drop suddenly and you won't know.

Here is a pic.

Thanks Shardul. I am getting the EC h/e and it is between the meziere or cm30 pump. Do you think the extra flow from the meziere is a benefit compared to the cm30 or have you seen data that shows it works better? I am only asking because of the posts where it said too much flow could make things not cool correctly.

I will definitely do both of those things. I think I have come across a DIY also, so it should not be too hard.

LOL, I am going to stick to EC h/e, but that is a good idea, let us know how it works.

Thanks for the correction!

A couple members said the EC is a replacement, is that not true or did they switch designs? On the conflicts, I was referring to past threads where members were debating if the extra flow was actually helping the situation or causing it to become worse because it would not cool things down before cycling. BTW, I know the meziere flows a lot more, but you think the cm30 is a better option? I want to only buy one pump lol and not have to buy another if I feel I made the wrong decision.

HadiLaw

You live in Arizona?? Get the meziere pump and never look back! Definitely split the ic system. I've never heard someone complain about the meziere but people are always complaining about the others.

You could just run 2 stock pumps, before and after. Remember when it comes to a H/E. surface area is better than thickness. Then again there is only so much H/E you can add, before you need something else.... And that is coming soon for all of you.

mikey33

Okay guys last question. I bought the eurocharged h/e but was going through threads and was reading that some people were doing two pumps instead of one, and I was under the impression this was because of a trunk reservoir and not just splitting the circuit. So, if I just split the circuit with no rear reservoir I only need one pump correct? Also, do I need to buy the Meziere fittings and what kind and many? Thx a lot.

alextaylor29

Mikey, I'm right behind you buying the E/C HE today in fact. I'm going to have Dynotek in Scottsdale install it so where can I find info on the "Split Cooling" system?

Thanks!

yes you are correct. you will need the 2 of the anodized AN fitting for the meziere. they sell it on their website.

mikey33

I did a search and found a few threads about it including one which was somewhat helpful.

https://mbworld.org/forums/w211-amg/...nger-prep.html

BTW, you know how much they charge to do the install?

Thanks for the help! BTW, do I need some kind of little reservoir for the split circuit in the engine bay also? Also, it looks like in pictures it requires two different types of fittings and not two of the same. Do you know if it is a 1" or 3/4" and part numbers lol? Sorry for the trouble, but I am about to order them and do not want to get the wrong stuff.

azncantonw211

I have the PLM....never had a issue with it, really easy to install with no additional modification.

mikey33

Do I need two of these fittings or something else?

yes one for inlet and one for outlet. if you split the system you will need a BMW power steering reservoir so you can use it has a fill point.

mikey33

So 1" is fine or do I need 3/4", also I saw in another thread marcusfrost used the barbed fitting. Is that better?

mikey33

Will this reservoir work?

follow these instructions and you will be set

the reservior seems fine make sure it come with a bracket so you will be able to mount it.
