June 8 (Reuters) - General Motors said Thursday it will invest more than $500 million in its Arlington, Texas assembly plant to prepare it for production of next-generation internal combustion engine full-size SUVs.

The Detroit automaker is making a series of announcements this month. Efforts to retool existing North American auto plants and introduce more efficient next-generation internal combustion models are also being planned, sources told Reuters. GM faces increasingly stringent emissions requirements from California and the Environmental Protection Agency (EPA). The total investments being announced this month could be around $3 billion, sources said.

On Monday, GM said it plans to invest more than $1 billion to re-tool two manufacturing sites in Flint, Michigan to prepare for a new generation of its internal combustion engine heavy-duty (HD) trucks.

The Texas investment will be used to provide new tooling and equipment in the stamping and assembly areas of the plant that manufactures the company's entire line-up of full-size sport utility vehicles (SUVs), including Chevrolet Tahoe and Suburban.

GM, which has vowed to end production of gasoline-powered vehicles by 2035, said the Texas announcement highlights the company's commitment to continue providing customers with a strong portfolio of (internal combustion)vehicles for years to come."

On Tuesday, GM said it would invest C$280 million ($210 million) in its Canadian Oshawa Assembly to produce the next-generation internal combustion engine full-size trucks.
