D24 D24T D24TIC? how to distinguish?

[alcinoloureiro]

Hi there crazy volvo lovers,

I live in portugal and am a volvo addict, i´m 60 yrs old and have about 10 volvos, a 765 D24TIC bought in France , a 765 D24 Bought in USA (LOVE THAt FRONT), a d24t 760, a 944 b200ft, a 245 d24 and a 164 3.0 and my LPG baby 765 PRV 2.8, a 242 GT and a 122

I also have loads of engines and gearboxs on my garage, i an now trying to rebuild a 765 and have many blocks but i want to make a D24TIC or at least a D24T, the problem is i don´t know hot to distinguish the blocks from a D24, D24T and D24TIC (if it is in anyway possible)

for example i have a block that has DN 021357 written, do you know if by there numbers/letters is it possible to find out if is it a turbo or non turbo engine??


Thanks and as soon as i can i will put some more pictures

I sure as hell wouldn't mind having your storage!

If the engine is complete, look at the front of the cylinder head, it will have D24T stamped in it, or D24 if it was orginally non turbo. As far as I know there is no difference between the D24T and Tic engine/block. If the head is already off, you will have to take the oil pan off and look up under the pistons and see if there are oil squirters present. If so its a turbo engine and the better block. If not, its a NA engine. There may be a engine block number database that you could look up the engine numbers to see what it was, but I don't know of one. Maybe a volvo dealer can look up the number.

Only the early engines have D24 or D24T stamped at the front of the head (1984 and before). '85 and onwards there is no designation stamped there.

A D24T block will have a coolant hose outlet pointing upwards right above the thermostat housing, low on the left side of the block, to supply coolant to the oil cooler and also will have a coolant neck on the back of the head where the return flow from the oil cooler circuit is received. A non-turbo D24 block has neither of those. That is probably the fastest and easiest external way to tell the block and head apart on NA versus T engines.

D24T and D24TIC are the same internally, the only difference is that the TIC is intercooled, has the turbo compressor housing clocked differently, uses a true air-to-oil heat exchanger instead of the coolant-based VW oil cooler, and has a "tropical" heavy-duty viscous fan clutch to make the fan move more air.

Any updates? Where are those images?

BTW, are the D24T and D24TIC heads the same or interchangeable?
