Tomcar Holding Company: finding your numbers, your engine and your parts

Who built the engine in your Tomcar Holding Company

Tomcar Holding Company, LLC is the name on the certificate filed with the US EPA. That is the company that brought the machine into the country, not the company that built the engine. The record names 2 different Chinese engine factories across Tomcar Holding Company's filings — which means the badge alone does not tell you which engine you have.

• Chery Engine Company
• Chongqing Zongshen

The numbers to find on the machine

Where these live depends on the shape of your machine rather than on the badge, so we do not repeat the search here — the sheets below cover it properly and are free. What matters for a Tomcar Holding Company specifically is which number settles things: with 2 factories on the record, the engine family number is what tells you which engine you have.

1. The emission control information label

   Carries the engine family number. This is the strongest identifier your machine has and the one most owners have never looked at.

2. The code stamped into the crankcase

   Survives when the label has not. It encodes cylinder count, orientation, bore and displacement class.

3. The VIN

   Identifies the vehicle rather than the engine, and its first three characters name whoever registered it for sale.

Engine families on the record for Tomcar Holding Company

If the label under your seat carries one of these, it is a Tomcar Holding Company and this is the certificate it was sold under.

How to search for a part

Searching the badge is searching the weakest information you have. These are built from Tomcar Holding Company's own record, roughly strongest first — replace <part> with what you need, and add the measurement you took.

1. 1CTCRX1.05TCF <part>
2. 21052cc <part>
3. 3Chery 1052cc <part>
4. 4Jingzhou Xintai Car Industry (Usa) Co., Ltd. <part>
5. 5Tomcar Holding Company, LLC <part>

The strongest search usually has no badge in it at all. An engine family number plus a measurement finds listings from sellers who have never heard of Tomcar Holding Company, which is most of them.
