Midwestmover Posted November 21, 2023 Share Posted November 21, 2023 Guys, new here, but I’ve got an ‘89 R model Mack and I’ve recently learned it must have been a glider Kit as the mondel number is RD600GK. It’s a non aftercooler engine and I’m not sure how to differentiate between an ENDT and a 2 valve E6. I’m needing g to find a top turbine aftercooler for it as a standard aftercooler would not fit in front of the radiator.

Joey Mack Posted November 21, 2023 Share Posted November 21, 2023 what does the data plate behind the injection pump say.. I just see an E-6, 2 valve .. ENDT means engine, diesel , turbo..

terry Posted November 21, 2023 Share Posted November 21, 2023 It’s a 237, beside the tip turbine I’m not sure what else needs to be done to make it a 285.

880joe Posted November 21, 2023 Share Posted November 21, 2023 Didn't e6's have drive in freeze where the endt's had screw in freeze plugs Quote Link to comment https://www.bigmacktrucks.com/topic/73563-endt675-or-e6/#findComment-542289 Share on other sites More sharing options...
JoeH Posted November 21, 2023 Share Posted November 21, 2023 What's the data plate say? It is a 2 valve, I'd bet E6 as the intake crossover tube and turbo/exhaust manifolds look a wee bit different than my endt-675's.

JoeH Posted November 21, 2023 Share Posted November 21, 2023 Someone wrote on here a couple years ago that the engine model should be stamped into the block just forward of the injection pump.

Midwestmover Posted November 21, 2023 Author Share Posted November 21, 2023 (edited) Sorry guys, I could only load a couple pictures. I’ll throw up the data plate now. Pretty sparse info on the data plate.

Joey Mack Posted November 21, 2023 Share Posted November 21, 2023 (edited) Looks like the re-man center didn't do its job with the data plate, I'm guessing it was rebuilt in 1990, the year that the E-7 came out.. maybe Mack can tell you what it is using the 11GBA number.. although, terry did say what it is... Looks good to me..

I left Mack in summer of '75 the drive in plugs had been showing up before that.

Freightrain Posted November 21, 2023 Share Posted November 21, 2023 The hell I went through getting block heater out of my 673 when I put spin on filters. Geez what a mess that was. Glad I got the new plug installed and didn't leak! Heater won't fit behind spin on filter housing. Quote Larry 1959 B61 Liv'n Large......................
