No, the 340 radiators are not the same as 740s. The D24t radiators are longer.

Just that you can rebuild them as many times as you want so they will essentially last forever. All the new ones you can buy nowadays are the cheap crappy aluminum-core kind with plastic end tanks and hose necks. Those can't be rebuilt and the plastic necks get brittle and can easily be broken off. When parts for these cars get more rare -- as they are already beginning to do -- it will be good to have parts that can be rebuilt and fixed rather than ones that have to be replaced because they are not rebuildable. Soon enough, there will be NO new radiators available for D24Ts and so your only option will be to adapt something that doesn't fit quite right, have a custom unit built for major $$, get something from a junkyard that is already half broken...... or, if you are lucky and happen to have an all-metal radiator, just have your existing rad recored and put it back in with little expense and hassle. That is why the metal radiators are desirable.

Did the head gasket on it. Put a composite 2 notch on there with a reamed out 80 head and N/A cam shaft. The JunkYard head had the shims WAY to tight! I had to loosen them all up ALOT. used ATF to clean the valve seats. man... We hit 700 PSI on one cylinder and the rest were ~500PSI this was before I ran it and DEAD cold outside temp was 30F. but then again, once we got the head on and torqued I put ATF down all the intake ports and rolled the engine over by hand a couple times forwards and backwards with injectors in. Then I took the injectors out poured more ATF down the injector ports and let it set for a couple days, then we turned it over again and let it sit some more. we spun it over a while with the starter to get the excess ATF out and to lube up the valves and get them cleaner checked the valve lash like 3 times during all this and they got looser and looser. this junkyard head decked out perfectly flat. but some of the valves had this junk on them. it seems weird but just needed cleaned.
All in all not bad. Soon I'll have the AFTER video up.

I found an 1980 240 n/a diese! at the junk yard. The car has been sitting for awhile. Alot of moss on the car the tags say 2003. The timming belt wasn't broken I tired turning over the car by hand and wouldnt budge. The block was really clean I pulled the valve cover off, and I was amazed the head has been recently been rebult. I took off the head and I notice the hold motor is a rebult. This head saved me alot of Money and time than going to a machine shop and getting the head resurface, and waiting for a week to get it back.
I change to oil yesterday with lubro moly fully synthetic diesel engine oil. Its slowly getting back on the road again. I will post more pictures later. Thanks Kevin for helping us...

I remember when Tyler did the headgasket on that white car. It was about two years ago.
He borrowed my tool to lock the crankshaft pulley in position so he could change the timing belt. He had overheating problems afterwards too, pulling heavy loads up long hills I think. He used an Evans waterless coolant at one time. I think you will find it still has the automatic transmission rear axle so at 80 mph you will be turning 3700 rpm. My auto to stick swap 745 is just the same. Makes the car quite peppy and the engine does not seem to mind the rpm. Steve |

Since the headgasket replacement there has been no problems of overheating at all. The gearing of the rear end did felt different from my 240 with a D24.

Been cleaning the engine bay. I was thinking of keeping the A/C thought it would be nice to have, but it was always getting in the way. The D24T radiator was in very poor condition so I rerplace a radiator from a 960 instead. The radiator from the 960 is the exact same size only a little thinner and was able to use the E-fan from that radiator. The 960 radiators don't have a spot for overflow tank on the radiator So I bypass it though the VW water oil cooler.

Interesting that you are using the electric fan. I have looked at doing that on my 92 conversion.
I still have the turbo gas radiator which is a wee bit thinner than the diesel but I also have an intercooler in there thats not being used. The electric fan was standard in 92. In order for it to fit, I will have to remove the mechanical fan pulley and shaft on the alternator bracket and get a shorter belt to run the power steering pump directly off the crankshaft. My biggest problem is that the std cooling fan is controlled by the gas engine ECU so I would have to arrange a temp switch on the plumbing somewhere and the rad has no orts for a switch. It looks like you have a big fitting assembly in the top rad hose. Is that how you do it? What switch do you use? It is also switched on by the a/c and I have preserved that system (not hooked up) although the a/c does not get enough cooling without the helper fan in front of the rad at present. I presently just have the 1985 stock mechanical fan and shroud on the 92 rad. Canning the a/c is not an option for me in SC. Steve |
