The Toyota 3C-T is a 2.2 L (2,184 cc, 133.3 cu·in) four-cylinders, four-stroke cycle water-cooled turbocharged internal combustion diesel engine, from the Toyota C-family, manufactured by the Toyota Motor Corporation from 1992 to 2001.
The 3C-T diesel engine has a cast-iron cylinder block with 86.0 mm (3.39 in) cylinder bores and a 94.0 mm (3.7 in) piston stroke. The compression ratio rating is 22.0:1 or 22.6:1.
The Toyota 3C-T engine has an aluminum cylinder head with a belt-driven single overhead camshaft (SOHC) and 2 valves per cylinder (8 in total).
The Toyota 3C-T engine produced from 88.0 PS (65.0 kW; 87.0 HP) at 4,000 rpm to 91.0 PS (67.0 kW; 90.0 HP) at 4,000 rpm of maximum output power and from 188.0 N·m (19.2 kg·m, 138.6 ft·lb) at 1,800 rpm of peak torque.
The breakdown of the engine code is as follows:
- 3 – 3-rd generation engine
- C – Engine family
- T – Turbocharged

Cylinder block
The cylinder block is made of cast iron. The crankshaft has 8 counterbalance weights and supported by 5 bearings. An 86.0 mm (3.39 in) cylinder bore and 94.0 mm (3.7 in) piston stroke give the 3C engine a total of 2,184 cc of displacement. The compression ratio rating is 22.0:1 or 22.6:1.
Pistons are made of high temperature-resistant aluminum alloy. The piston pin is full floating. Each piston is fitted with two compression rings and a single oil ring. The top ring is made of stainless steel, the second ring is made of cast-iron.

Very useful information, thank you
Aslaaim u alaikum
i have changed my vehicle engine oil with 20w50 senthatic oil is it better or not
I prefee 15w-40w.. normal toyota engine oil is better.
I recently overhauled a 3CT diesel engine (townace 1995 model). When i started the engine there was pressure build up and bubbles coming from radiator. What can be the problem?
I am having the same
I open the cylinder head of estima 3c automatic trans…when s started there is a cracking noice
