MB 617 turbo engine oil Cooler VS Aftermarket - PeachParts Mercedes-Benz Forum

coachgeo · #1 04-18-2003, 02:29 PM

Any one have any information about advantage/disadvantage of going to a domestic engine cooler over the MB one? My 617 turbo had a cooler on it from a 90 or 91 MB so parts were mixmatched already. (new replacement $300 smakeroo's)

Advantage domestic: Easier to find, maybe cheaper in cost

Disadvantage domestic: ?

Since you didn't have the cooler from a 617 turbo anyway, look for a cheaper Mercedes cooler. Performance has one for a 240d for $132. One from a junkyard should be a lot cheaper.

Well there lies of of the disadvantages Kerry. An after market NEW one is HALF the price of the used one you just mentioned. Granted money is not everything... Im trying fo figure out if their are other reasons to use or not to use an aftermarket.

Coach - I would just pick up a cooler from a performance parts place then I would go to a hose shop to have custom hoses made up with the correct fitting at each end. This stuff is done all the time by hot rod builders.

I went to Summit Racing today just for this very idea Engatwork. Kerry it appears I was wrong. They are cheaper than MB used but not by much.

Anyway, I left empty handed causeee. I didnt know what Gallons Per Minute to get. Below is some examples

PRM-201 18 in. long x 6 in. wide x 1 1/2 in. high, 1/2 in. NPT fittings, 3-10 gpm flow rate, three tube, single row he... $99.95
PRM-301 20 in. long x 8 in. wide x 1 1/2 in. high, 1/2 in. NPT fittings, 4-14 gpm flow rate, four tube, single row hea... $129.99
PRM-501 20 in. long x 9 1/2 in. wide x 1 1/2 in. high, 1/2 in. NPT fittings, 4-16 gpm flow rate, five tube, single row... $179.99
PRM-601 20 in. long x 11 1/2 in. wide x 1 1/2 in. high, 3/4 in. NPT fittings, 4-18 gpm flow rate, six tube, single row... $219.99

What do you folk figure I need for GPM? The 18" barely fits in hight if I mount it where it was before. It was mounted vertically with both hoses on top.

not all were listed by GPM...!! So its hard to decipher. There are others here at Summit Racing

I am considering a dual circuit cooler. The second side eventually being manuel tranny oil. Unimog 404 trannies have a history of heat problems at highway speeds. They love crawling like a tractor but hate highways. Any thoughts on this.

bump up

I would select one that fits and is easy to mount versus the gpm. I don't think you have anything to worry about with the flow as much as how/where to mount it.
