    Default Olsen oil cooler core cleaning

    what do you guys recommend for cleaning the cores to insure all the debris is removed after an engine failure? I have some ideas about making up a air/agitation type cleaner apparatus either using the cooler body or something larger to promote more fluid/agitation/flow etc. Radiator shop? other ideas?

    Do the ends come off, so you can CLEAN?
    If not, toss it.
    I have had customers fight that fight before. ALWAYS ends the same way.

    Take the ends off. Buy an O-ring kit from Rex Marine so you can put all new O-rings in it and you can do a very thorough cleaning. With the new O-rings it will be as good as new.

    The end caps come off an Olson cooler, but you still don't have a good way of cleaning between the tubes. Water runs through the length of the tubes, and oil passes over the outside of them and is channeled to make several passes from one end to the other.

    I believe there are places that you can have the bundle of tubes professionally cleaned, not sure where to send you. Likely Olson would know. Filter should catch any remaining debris assuming you have no bypasses, and cooler is before the filter going back into the block.

    Might try a Muratic acids cleaner for AC coils from Home Depot , make sure it is copper safe first , Olsen coolers come apart , you can get a oring kit direct from Olsen , I did ...ask for Brian in sales

    Thanks for the replies guys. Yes, it's the large, block mounted OC201 unit so it does come apart. I have it plumbed with the large HP6 style remote filter assembly on the stringer via a Olson remote filter adapter head I purchased from Olsen. The spaces between the cooler core tubes is very small and compact and has me concerned about the reasonable viability of actually getting it completely clean. I was just curious to know what the experienced racers do as they are likely to have encountered this at some point. I have inquired with Brian @ OMS but understandably he has offered no response. ( liability concerns no doubt) When considering the cost of a new core vs. the potential of damaging a new motor the correct answer is obvious. Guess I'm just being cheap. I have a couple to clean. Additionally, I bought a nice polished unit several years ago from a nice guy here on the boards that was having a bit of a learning curve on building his blown gas flat deal and I didn't consider the potential ramifications of the core possibly retaining some materials. My bad. I've thought of creating a system using a elec. fuel pump, paint thinner type solvent and a Oberg type filter assem. to verify the cleanliness etc. Also thought some air injected for agitation at the core area might help to dislodge and carry the debris away. Seems like a reasonable system but being wrong could prove costly.

    I rigged and plumed it quite a while ago so at the moment I'm not certain about the filters position in the oil flow pattern. I will review that and reconsider the system with that in mind. I have been considering adding an Oberg type filter to the system but after reading threads here and elsewhere I became concerned about excessive flow restriction from excessive filtration. How do you guys prefer to set up your systems? Would it be reasonable to maybe place an Oberg type deal before the block mounted cooler with a less restrictive larger micron screen and the HP6 after for more ultimate filtration? or vise versa? It's a wet sump deal with stock style oil pump and a stef's large steel pan.

    I did a little 'Bing about' and found a couple co's. Monarch Deburring in Santa Ana ( right around the corner from Embee powder coating) said he sold his big machine to another guy locally but didn't have a number handy for him. He's was to look it up and call me back but I haven't heard back from him yet. His remaining equip. is too small for this size part.

    However, this company- Ultra Sonic Cleaning Corp. in Carson CA. (310-327-7103) I gave a them a ring and the guy I spoke with said no problem, $65.00 to do complete assembly, cooler core, casting body etc. disassembled. They can also do pressure testing for an additional $15.00 if you like. He said they do a lot of oil cooler cores and parts for Porshe, Ferarri etc. I'll let you know how it looks/goes after their done. Thank's for the feed back guys.
