I thought this was about Oil Coolers...well maybe it was once.

I added oil coolers after 1997 when I found that my older son's standard Mini 1000 power unit saw very high indicated coolant temperatures & low oil pressure when climbing the shortish but steepish hills in southern Oregon on the way to MMW in Vallejo, California.  (NOTE - 'steepish' for a 998cc, my younger son ran on up & over the hills in his Mini with MG Metro 1275 power unit).

When I built the 1380 and had a radiator recored by a local specialist shop, I was advised 70% more cooling efficiency than the stock core.  Went off to MMW 2006 in Arizona with the trailer in tow and had significant indicated coolant temperature rise after ambient temps hit 95 F.  No such temps heading east to MME in Maryland...BUT I added an auxilary radiator and all problems disappeared.  Cooling system could not cope with 1380 & 2,500 pound Mini & trailer over 95 F.

Long story short, will NOT be adding an oil cooler to the 1293 but will have extra radiator to add for hot weather travel.  

Im using water wetter and water now. I used to mix the 50/50 with water wetter. What do you all use?

why? you don't agree on what Alex said about the 50/50?.....i believe him,, ...relax Mr. J...don't faint....lol

Is someone available to take me to the E.R. or urgent care ?

I've resisted responding to this thread and have injured my hand, bruised my back and dislocated my shoulder patting myself on said back.



Thanks 

50/50 isn't good at transfering heat - from memory you lose about 30% of your cooling capacity when you run antifreeze that strong.

The clue is in the name - Anti Freeze...
In the summer you just need a splash, 5-10%, as a corrosion inhibitor.

Have a Google on the subject, KC wrote a few article about it back along.

Nothing wrong with 50/50. Just keep looking for causes why you're overheating. Could be your timing, running lean, blockage, fan installed backwards etc. I do know that electronic cooling fan works very well for me especially when stuck in traffic.

but back to the main subject... I still have my oil cooler. Thinking of removing it but after talking to some friends., I'll try and buy an oil temp gauge and see where I'm at.

ok,thanks sir Dan, now i can sleep tight knowing that my mini has now known mechanical issues and can cross the country anytime i want to.

and thanks sir Armycook, yeah i think i need to switch to water wetter soon, since the temp in my place ranges from 115 - 125F during summer.  and I'm sick and tired of the 50/50 coolant, doesn't do anything to cool my engine... thanks for the advice.  



Now my next problem is how to drain my radiator, i really wish sir issigonis at least put a drain plug in the bottom of the radiator(not on top), and I believe there was no coolant or antifreeze back in the days, they only use water from the rain in their radiators.
 anyway, i'll find a way to drain it for sure.  thanks much!!

mini4ever: Try water wetter plus water.

Yes, for months you've been complaining and ranting about how Mini engines do not handle heat well, only to find out yours is fine. By the way, the Mini temperature gauge is not very accurate... that's why there's no numbers on it. 

On a related note, my high compression 1275 experienced a slow rad hose leak that did not display steam. I was heading home at about 80 kph (50mph) and noticed a gradual loss of power. In fact what was happening was that my engine had lost coolant and was overheating to the point of beginning to seize. I coasted and coaxed it into a parking lot and called my wife to bring a rope and tow me the rest of the way home. I just let the engine cool down slowly and gradually and didn't add any coolant until it was stone cold. Tightened the the hose and refilled it with coolant. Absolutely no damage done, except that the faded red paint on the head looks darker and duller now. It pays to be attentive to your car as you drive.

Side note: the temperature sender reads coolant temperature... no coolant means it does not read properly!

Wow sir Dan, it means that my cooling system is in tiptop shape,  our temp here is 117F.  And yet my temp gauge only goes that hot. Doesnt even get close to H.  Im so proud of my mini special.

thanks

That would be pretty normal for 80 deg weather around here. The real test is whether it starts to blow steam out the rad overflow tube with a good rad cap of the right pressure range. No steam = no issue.

Pls see pic...
is this considered overheating?  I was riding yesterday with outside temp of 117F.  And this is what my gauge read after 1hr of driving. This one is at traffic light.  When i drive around it started to go down  below N mark.

normal or not normal??

It doesn't sound like a classic mini component, so why don't you first ask one of your many banned personas?  I'm sure many of us are really curious as to why you think you need an oil cooler.  What temperature is your oil running at under load?  Any chance you can take a snapshot of your oil temperature gauge???

You certainly presented yourself as an expert when you, under the nom-de-plume 'Boison', posted this tripe earlier in the tread:


You also claim to be clever:



I'm sure you're clever enough to navigate the articles pages, including this site's online parts diagrams or search the message threads in order to find out how proper mini oil coolers are installed.

Oh, and regarding this:


My name is John, not 'Juan'.  I don't think you want to do this again.  By the way, I haven't 'turned Danish' either, I'm still 100% American. 

Nothing was co-authored, I created this heirloom collectible tome for the lower social echelon's scavenging masses.  I'm glad you found it usefull.

You've probably wasted $3. It looks like a transmission oil cooler, and probably wouldn't stand up to Mini engine oil pressure. 
.

I'm currently installing an oil cooler on my mini. i bought an old but unused oil cooler from swap meet for $3. it's about 8inches by 12 inches and 2 inches thick. and the couplings are not screwable, they are attached with clamps. 
any idea how to install it? what hose and attachment should i buy? thanks

Having lost my 'military bearing' on a several occasions, I fundementally agree with both of you.  It's funny, isn't it; one never forgets how to be an animal.  I'd like to lose it one more time...

And believe me, Tony's just acting like he doesn't know anything - he does that everytime he backs himself in a corner.  Every time he spells 'come on' as 'cum on', or 'jeez' as 'jizz', he'll claim he doesn't know any better.  He knows darned well what uniforms symbolize and precisely what he was doing.  He thinks you're all 'inferior' and won't get it.   

We've all seen him in the picture from the church egg hunt - and the fact that he used to box in NY - connect all the dots, put one and one together and you'll find he's a disgrace.  A real p*ssy.  Worthless and weak.  An idiot.  A coward. 

My E-mail is in my profile if anyone wants to talk -

 

Cook, I assure you I share the sentiment. I can guarantee he wouldn't say it to my face whether I'm in uniform or not. And if he did, he would have a difficult time talking for a few weeks there after. I try to keep myself in check and not find myself unbecoming, but I won't standby and let a brother in arms be disrespected by someone like him.

I don't know what else to say to you Boison. I want to educate you a little bit. In the Army, we are all infantry first, second is just our MOS. a lot of people degrade my job in the Army because I cook but I hold my military integrity to the highest standard. I served in the Navy as a helicopter mechanic as well. We cook wearing ACUs, cook whites with aprons, and all those are all military issue with my rank and division insignia. It does not matter how in what manner it could be but you will never disrespect and mock my uniform especially if you already got your naturalization or green card. It just shows you do not deserve to be living here. And quite frankly you will not want to get caught doing that in person around military folks because I swear you will wish you didn't say anything at all.

We all know how dumb you are but you can leave my uniform alone. Enough with your lame excuses. You ****ed up so just man up.

Anyway I admit it's been fun and I had a blast enjoying myself making stupid replies but I don't want to participate in anything about you anymore. I'd like to ask for an apology to the OP and everyone for making a bad example of how a military vet would behave. 

think whatever u want to think, if you want to think otherwise its up to you, all i know is that i am talking about the white chef uniform because he said in his previous post that he was a cook in the army,and of course you cannot cook wearing an army suit, it needs to be the white apron thing.    cameron is very assuming, if i am your wife im going to divorce you right away for sure.

You are full of $hit as usual Boison. You are fully aware of Army Cooks proffesion be it past or present, it is just another one of your innuendo's and derogatory remarks. I know you can read just look at his screen name.
